The 25 Largest Yachts in the World

The list runs from lürssen's 592-foot 'azzam' to fincantieri 439-foot 'serene,' with a fascinating group of bespoke vessels in between..

Top 25 Superyachts Now

The new arrivals in 2024 knock the mighty 436.4-foot  Al Mirqab   and  Koru , Jeff Bezos’s sailing yacht, off the list. The “smallest” yacht— Serene —measures a whopping 439.3 feet. A raft of behemoths didn’t make it, including Feadship’s 290-foot Project 821 that is launching this year, the largest build from the Dutch shipyard to date.

Two of Lürssen’s 2024 deliveries also fell short, including Project Deep Blue and Project JassJ. That said, the German yard remains top of the leader board with the immoveable 592.6-foot  Azzam . It also claims 13 of the 25 world’s largest yachts, two of which are new entries.

The list is interesting because most were built in the last 15 years, but there are several historical yachts, including  Savarona , launched in 1931, and  El Mahrousa , launched in 1865, that withstand the test of time. Others like  Yas  and  OK are conversions from other types of vessels. The inimitable  A  is a one-of-a-kind, never-to-be-repeated sailing superyacht.

Here are the world’s top 25 yachts by length.

Azzam | 592 feet, 6 inches

Lürssen Azzam

Lürssen could never really boast about Azzam after its launch in 2013 because of the owner’s penchant for privacy, though it did describe the interior by Christophe Leoni, which features a 95-foot-long main salon, as “inspired by the Empire style of the early 19th century.” Owner Mubarak Saad al Ahbabi directed a team of designers and engineers who started with the bare concept, worked through the technical challenges of what might be the most complex superyacht ever, and finished with an unusually large vessel that can top the 30-knot mark when operating in “sprint mode”. Its gas turbines, connected to water jets, also give it the ability to operate at high speed in shallow waters. Nauta Yacht’s exterior features a long, sleek forward area, with well-proportioned tiers moving up to the skydeck. It took an impressive six million man-hours—or four years including engineering—to build.  Azzam  accommodates up to 36 guests, and a crew of 80.

Fulk Al Salamah | 538 feet, 1 inch

"Fulk Al Salamah," Mariotti Yachts

Little information has been released about the world’s second-longest superyacht, the custom-built Fulk Al Salamah , and it has been shrouded in mystery since it was first announced in 2014. Even the overall length of 538.1 feet has been estimated from AIS data. However, the imposing vessel, built and delivered by Italian builder Mariotti Yachts in their Genoa shipyard in 2016, is believed to be owned by Sultan Haitham bin Tariq of Oman. Last refit in 2021, the yacht has an exterior design by Studio de Jorio, and it is considered by some to resemble more of a support vessel than a superyacht. Nonetheless, aerial photography shows an impressively large helideck, raked masts, and a bathing platform.

Eclipse | 533 feet, 1 inch

Superyacht Eclipse

The 533.1-foot stately  Eclipse , one of two yachts on this list owned by sanctioned billionaire Roman Abramovich, took five years to design and build. When it left the Blohm+Voss shipyard in Hamburg in 2010, it was the world’s largest yacht. The interior has 17 staterooms and a palatial primary suite, with the capacity to carry 85 crew. Both the interior and exterior are designed by Terence Disdale. A proportional profile is defined by tiered decks that sweep upward and bend ever so slightly at the aft ends. Eclipse  has a 185-foot-long owner’s deck, the capacity to hold three helicopters, a sophisticated stabilization system, six tenders, and an enormous spa, gym and beach club, not to mention one of the largest swimming pools on any superyacht. Hybrid diesel-electric engines are connected to Azipod drives that give Eclipse a top-end speed of 21 knots, with a range of 6,000 nautical miles.

Dubai | 531 feet, 5 inches

DUBAI UAE - DEC 16: Dubai - yacht of the Sheikh Mohammed bin Rashid Al Maktoum the ruler of the Emirate of Dubai. December 16 2014 in Dubai UAE

Even at 531.5 feet, Dubai ’s all-white Winch-designed exterior belies the dramatic and vibrant interior within. Colorful mosaic floors, a spiraling glass staircase, 70-foot-wide atrium, and bursts of red, blue, and green create a carnival of scene. Originally commissioned for Prince Jefri Bolkiah of Brunei as a joint project between Blohm+Voss and Lürssen . Known as “Panhandle,” the project was halted in 1998 with just a bare hull and skeletal superstructure. The hull was sold to the government of Dubai, and, under the direction of the country’s ruler, Sheikh Mohammed bin Rashid Al Maktoum, work on the 531.5-footer began again, though this time by Platinum Yachts. Dubai delivered in 2006 and is now the sheikh’s royal yacht, with accommodations for 24 guests and quarters for 88 crew. The SOLAS-certified seven-decked yacht has a landing pad for a Black Hawk helicopter, submarine garage, disco and cinema, and can reach a top speed of 26 knots. There’s also a waterfall that cascades from the yacht’s pool, located aft of the main deck. The yacht’s range of 8,500 nm at 25 knots gives it the potential to cruise around the world in record time.

Blue | 518 feet, 3 inches

Lürssen Superyacht Blue

Lürssen’s newest entry on the list, Blue , which delivered to its Middle Eastern owner in July 2022, may rank at number five out of the world’s largest yachts, but its diesel-electric hybrid propulsion system goes a long way to minimize emissions. The yacht also features an electric Azimuth pod drive that can be used independently or in conjunction with the twin propeller shafts. There is a waste-water treatment system and an advanced exhaust treatment system to help reduce NOx levels, as well as cut down on vibration and noise pollution. Interior and exterior design is by Terence Disdale, Blue is defined in profile by a raked bow with a helipad, an aft deck pool, and twin balconies forward either side of the owner’s full-beam suite. There is a second, smaller helipad aft. The British designer has reportedly penned a feminine and elegant interior, though no images have yet been released.

Dilbar | 511 feet, 8 inches

Espen Øino Dilbar yacht

The 2016 launch of Dilbar gave Lürssen the distinction of not only building the longest yacht ever ( Azzam ), but also the largest in terms of volume. Espen Øino designed the exterior, creating a full-bodied superstructure of long, flowing decks, along with two helicopter pads,two helicopter pads, one of which has a hangar with an H175 helicopter always on standby.  Dilbar  also has an oversized garden and an 82-foot swimming pool that can hold an incredible 6,357-cubic-feet of water and according to Lürssen, is the world’s longest on a yacht. The interior by  Winch Design  is defined by its “rare and exclusive luxury materials,” says the builder, declining to go into detail. Despite  Dilbar ’s volume, the designers did a masterful job making the yacht look relatively svelte. In June 2020, Dilbar returned to Lürssen for a significant refit, where the yacht remains following U.S. sanctions placed on the owner, Russian billionaire Alisher Usmanov, in 2022. The yacht’s value is estimated to be $600 million.

Al Saïd | 508 feet, 5 inches

Al Said measures 508'5" and was built by Lurssen Yachts

Another 500-plus-foot yacht from Lürssen, the original Project Sunflower gained its official name of Al Saïd following its launch in 2016. Espen Øino’s exterior is akin to a classic cruise liner, complete with the twin-exhaust stacks in the center of the superstructure. Owned by the Sultan of Oman, the yacht was listed for the sale for the first time in April 2022 for an undisclosed sum, but a buyer has yet to be confirmed. The six-decked  Al Saïd  can carry 154 crew and an estimated 70 guests across 26 suites. Lürssen reports a top speed of 22 knots. The London-based Redman Whiteley Dixon studio designed the interior, which includes a concert hall that can hold a 50-piece orchestra, a private cinema for 50 people; you’ll also find a medical room and dental care on board.

A+ | 483 feet, 1 inch

Lürssen Topaz largest yachts in the world

Very little is known about A+ (formerly Topaz) , which was launched by Lürssen in 2012. Tim Heywood Designs did the exterior, which features helipads on the foredeck and amidships on an upper deck. A lower aft deck includes a swimming pool. The German yard has not released any images of the Terence Disdale interior. Reported to be owned by Manchester City Football Club owner Sheikh Mansour bin Zayed al Nahyan—Emirati royalty and deputy prime minister of the UAE— A+  is equipped with a 40-foot Vikal catamaran beachlander and is powered by six Wärtsilä engines to reach a top speed of 22 knots. It can carry 62 guests and up to 79 crew and was last refit in 2022.

Prince Abdulaziz | 482 feet, 3 inches

Prince Abdulaziz

The 5,200-tonne Prince Abdulaziz is one of the Saudi Royal family’s yachts, its first owner being King Fahd. Designed by Maierform, the yacht was the longest and tallest in the world at the time of its launch, a title the 482.3-foot  Prince Abdulaziz  held for 22 years until  Dubai  launched in 2006. The late David Nightingale Hicks, known for his use of bright colors, was the interior designer. The lobby is said to be a replica of the Titanic . The yacht is also rumored to be carrying surface-to-air missiles, though that may be an urban legend. Launched by Helsingør Værft in Denmark in 1984, it was last refit in 2023.

OK | 479 feet

Ohima Shipbuilding's OK

Originally built by Japan’s Oshima Shipbuilding in 1982, the semisubmersible heavy lift ship was used for decades by DYT Yacht Transport as float-on yacht carrier. In 2022, the vessel underwent a private conversion at Karmarine shipyard in Turkey, turning it into a luxury, though highly unusual, yacht named OK . Modifications include a matte-black paint job, gold-tinted glazing, and teak decking. The vessel’s 328-foot submersible aft deck—a feature that first attracted her new owner, who uses OK to transport their 150-foot ketch—is now covered in a carpet of artificial grass. A 40-tonne crane allows for the safe and easy launch and retrieval of a vast range of toys, including a seaplane. The interior by Bozca Design is reported to include accommodation for 20 guests, a botanical garden, and a crazy Willy Wonka–inspired glass elevator that operates outside of the yacht’s superstructure.

Opera | 479 feet

Lürssen Yacht Opera

Very little is known about Lürssen’s mysterious superyacht Opera , though it’s thought to be a rebuild of Project Sassi, which was destroyed in a fire in 2018 at the German shipyard. Now four feet longer than the first iteration, the superyacht became the 11th largest yacht in the world when it delivered to its patient owner in 2023. Exterior and interior designed by Terence Disdale, Opera has a whopping 66-foot beam and an interior volume exceeding 10,000GT. No interior images have been released yet, though judging by its two swimming pools, one with a lifting floor, and two helipads—one on the bow and one on the upper aft deck—it seems no expense has been spared.

El Mahrousa | 478 feet, 1 inch

"El Mahrousa" Yacht, Samuda Brothers

El Mahrousa , which means “The Protected” in Arabic, is currently Egypt’s presidential yacht, though the 478.1-footer has a separate history as that country’s royal yacht. The London-based Samuda Brothers began the build in 1863, and it was launched in 1865. The world’s oldest superyacht—and formerly the world’s biggest—was originally built for the Ottoman governor of Egypt, Khedive Ismail, and later carried three Egyptian kings into exile. The yacht was also at the opening of the Suez Canal in 1869. It features external design by the British naval architect Sir Oliver Lang and has had multiple modifications over the years, including a lengthening by 40 feet in 1872 and another 17 feet in 1905. During the second refit, the owners replaced its paddle-wheel engines with turbine-driven propellers. The yacht, in care of the Egyptian Navy, occasionally goes to sea for a day or two. In 2015, it was used to inaugurate the new Suez Canal.

Project Luminance | 475 feet, 7 inches

Superyacht Lumaniance

Delivered in 2024, Project Luminance (the real name is yet to be confirmed) is Lürssen’s newest entry on the list. Exterior designed by Espen Øino, the yacht has a raked bow, a contrasting paint job in a dark blue hull and silver superstructure and a whopping 8,999 gross tons of interior volume. Few details are yet known about the gigayacht owned by Ukrainian mining and financial services mogul Rinat Akhmetov, including the interior by Francois Zuretti, but aerial shots reveal twin helicopter pads—one on the foredeck and another high up aft—a large beach club, and an infinity pool, with a private spa pool area on the foredeck.

A | 468 feet, 5 inches

Nobiskrug sailing yacht A.

Undoubtedly one of the most visionary projects ever delivered by German shipyard Nobiskrug, the Philippe Starck-designed A is a wild fantasy of the future. Delivered in 2017, the futuristic look of  sailing yacht  A includes smooth, silver-metallic surfaces and windows that look nearly invisible, a 26-foot draft, three composite masts that bend slightly, and a deck hidden by high bulwarks. The Philippe Starck–design is a wild fantasy yacht of the future. The 468-foot sailing yacht is a technical victory for Nobiskrug , which developed composite fashion plates to create the unusual shapes without compromising any strength or fluidity. It has the tallest freestanding composite masts on any sailing vessel, a diesel-electric propulsion system, and state-of-the-art navigation systems. The boat also reportedly has an underwater viewing platform in the keel. Starck’s traditional interior features dark wood, copper accents, and cozy patterned carpets. The split-deck main salon is divided into zoned seating areas with integrated bookshelves. A remains today the world’s largest sailing yacht six years after its launch, though many argue it is better defined as a sail-assisted yacht.

Nord | 466 feet

Lürssen OPUS Launch

Nord was announced in 2015 but didn’t hit the water until its 2020 sea trials in the Baltic Sea. The 466-foot yacht features interior design by Italian studio Nuvolari Lenard and was Lürssen’s first yacht launched from its floating shed at its facility in Vegasack. Boasting top-tier amenities, the yacht includes a sports and diving center on the lower deck, multiple tenders ranging in size up to 50 feet and a large swimming pool. The two helipads support the yacht’s long-range cruising capabilities for autonomous exploration, and a retractable hangar means a helicopter can slide neatly into the superstructure for storage when not in use. A generous 20 staterooms accommodate 36 guests across six decks, while a sleek aft-sloping superstructure gives Nord an individual profile on the water.

Yas | 462 feet, 6 inches

Superyacht Yas in Barcelona

As a converted yacht, Yas is one of the most interesting vessels on this list. The dolphin-like exterior was originally a former Dutch Navy frigate that launched in 1978 and eventually sold to the navy of the United Arab Emirates, where it was renamed Al Emirat . The yacht underwent its dramatic conversion in a facility in Abu Dhabi’s main port, emerging as a gleaming superyacht in 2011, with one of the most interesting profiles on the water. It was eventually delivered four years later. Reportedly owned by Sheikh Hamdan bin Zayed al Nahyan, half-brother of the president of the UAE, Khalifa bin Zayed Al Nahyan, the design by Paris-based Pierrejean Vision is defined by massive glass surfaces. Yas can accommodate 60 guests and 58 crew members. Mated to a steel hull, the superstructure is the largest composite edifice ever built.

Solaris | 459 feet, 3 inches

Russian oligarchs yachts continued to be seized

Owned by Russian businessman Roman Abramovich, the 476-foot  Solaris  was one of the largest yachts to deliver in 2021. Last refit in 2022 at MB92 in Barcelona, the vast, highly private explorer is built by German shipyard Lloyd Werft and features a displacement steel hull with bulbous bow and steel superstructure with teak decks. The eight-deck exterior by Australian designer Marc Newson houses a large helipad, sundeck, spacious beach club aft and 21,527 square feet of glass, the largest panes to ever be built into a yacht. Lloyd Werft also built the Russian billionaire’s previous explorer yacht Luna , which he reportedly sold for $360 million to his close friend Farkhad Akhmedov in 2014.

Ocean Victory | 459 feet, 3 inches

Fincantieri Yachts’ 459-foot Ocean Victory Photo by Trevor Coppock / TheYachtPhoto.com

The largest motoryacht ever built in Italy, Fincantieri’s Ocean Victory is owned by Russian billionaire Viktor Rashnikov, who was sanctioned in 2022. The seven-deck exterior by Espen Øino includes two helideck platforms and a hangar belowdecks, as well as exceptional outdoor social areas and a floodable tender dock. Ocean Victory has accommodations for 28 guests as well as quarters for 56 crew. The interior by Alberto Pinto remains a secret, aside from the yacht’s six pools, a 3,300-square-foot spa, and an underwater observation room.

Scheherazade | 459 feet, 3 inches

Russian oligarchs yachts continued to be seized

The 459.3-foot, Lürssen-built Scheherazade (formerly known as Project Lightning) was delivered in June 2020, with exterior design by Espen Øino and interior design by Francois Zuretti. Two helipads, forward and aft, and a large beach club aft are visible from aerial photographs, but aside from the yacht’s reported seven-foot beam, 40 crew and unique drone-crashing system for privacy, further details have not yet been released. The reason may lie with the yacht’s unofficial owner, believed to be Russian president Vladimir Putin. In May 2022, Italian authorities froze Scheherazade in the port of Marina di Carrara following an investigation conducted by Italian financial police who found the ship’s beneficial owner had “significant economic and business ties” to high-ranking Russian government officials, though the results of the investigation to date remain inconclusive.

Al Salamah | 456 feet

Lürssen Al Salamah gigayacht

When Lürssen launched Al Salamah in 1999, it was the third-largest yacht in the world. Its number 20 ranking shows how much has changed in the last 20 years. Code-named MIPOS, or Mission Possible, the yacht was designed by Terence Disdale . Originally owned by Saudi Arabian Crown Prince Sultan bin Abdulaziz, the yacht was put up for sale for $280 million in in 2013 before it was reportedly given to Bahraini Crown Prince Salman bin Hamad Al Khalifa as a gift. The large imposing exterior is primarily protected space, with an upper deck exposed to the elements. Al Salamah has staterooms for 40 guests, including two owner suites, 11 VIP staterooms, and eight twin cabins. The yacht can carry up to 96 crew and has a top speed of 22 knots. Al Salamah was last refitted in 2009.

Rising Sun | 454 feet, 1 inch

Lürssen Rising Sun superyacht

Designed by the original guru of yacht designers, Jon Bannenberg, Rising Sun was built by Lürssen for Oracle CEO Larry Ellison and is currently owned by billionaire David Geffen, who reportedly paid $590 million for the yacht. The yacht comes with a gym, a grand piano, multiple swimming pools, a beauty salon, and a spa with a sauna. Delivered in 2004 and last refit in 2022, the yacht’s exterior is defined by banks of windows across the superstructure. Rising Sun has 86,000 square feet of living space in 82 rooms. It can accommodate 18 guests in nine cabins, with the capacity to carry up to 46 crew. The interior by Seccombe Design includes a gym, cinema, and wine cellar, and the rear cockpit deck was designed as a basketball court. Geffen received global media backlash in 2020 for his “tone deaf” social-media posts that pictured himself on board his yacht during Covid-19 lockdown.

Flying Fox | 446 feet, 2 inches

Lürssen's Flying Fox superyacht.

The 446.2-foot  Flying Fox is arguably the most high-profile yacht on this list, primarily for being the largest yacht available on the charter market. In 2022, it was also singled out as “blocked property” by U.S. authorities in 2022 due to its previous management Imperials Yachts, which was on the US sanctions list. The yacht’s owner, however, Russian billionaire Dmitry Kamenshchik, is not sanctioned, so the yacht was turned over to him and returned to charter in 2024. Key features of the Espen Øino-designed exterior are a curvaceous dove-gray hull and a 3.7-foot swimming pool that runs athwartship on the main aft deck, the largest ever found on board a yacht. A two-decked spa also gives guests access to a cryosauna, hammam, and relaxation room with a fold-down balcony at sea level. Packed to the rafters with the latest amenities, the yacht holds a diving center, a decompression chamber, and two helipads. Flying Fox is PYC compliant and can accommodate 25 guests.

Savarona | 446 feet, 2 inches

Savarona superyacht 25 top yachgts

Launched in 1931, and by far the largest and fastest private yacht of her day, Savarona was built for American heiress Emily Roebling Cadwalader and is easily identified by its two mustard-colored funnels. The yacht was eventually acquired by Turkey to be the presidential yacht of Kemal Atatürk, founder of modern Turkey. Jane’s Fighting Ships described the yacht in 1949 as “probably the most sumptuously fitted yacht afloat.”  Savarona was later converted to a training ship for the Turkish Navy and, in 1978, destroyed by fire. The yacht laid in tatters for 10 years. A Turkish businessman spent around $45 million refurbishing Savarona , commissioning Donald Starkey for the interior and replacing the original steam-turbine engines with modern Caterpillar diesels. Savarona became Turkey’s official presidential yacht again in 2014, accommodating up to 34 guests in 17 suites and carrying up to 48 crew. Amenities include a swimming pool, a Turkish bath, a 280-foot grand staircase, a movie theater and a library dedicated to Atatürk.

Crescent | 443 feet

Lürssen Crescent superyacht Larry Ellison

Last refit in 2021, Espen Øino’s dark hull and tiered superstructure was one of the most exciting launches of 2018. Called Project Thunder internally at Lürssen, the custom-built yacht features cutouts along the hull sides that allow full ocean views from the saloon on the primary deck, as part of Crescent ’s distinctive curved superstructure. Its most noteworthy feature is the jaw-dropping bank of three-deck-high windows in the center of the yacht. This architectural feature serves as the centerpiece of a very compelling design. The yacht has accommodations for 18 guests in nine staterooms. Little is known about the François Zuretti-designed interior, other than Lürssen describing it as being “traditionally styled.” If it lives up to Crescent ’s brash exterior, the complete yacht promises to be an entirely groundbreaking design. In March 2022, Crescent was detained by Spain as property of Rosneft CEO Igor Sechin, who is sanctioned in connection with Russia’s invasion of Ukraine.

Serene | 439 feet, 3 inches

Fincantieri Serene superyacht

Serene  is the yacht that launched Fincantieri into the superyacht segment, and what a debut it was. The largest yacht ever launched in Italy when it was delivered in 2011 (surpassed three years later by Ocean Victory ), the Espen Øino seven-deck design features a long, sleek blue hull crowned by a white superstructure. Pascale Reymond of Reymond Langton Design created the 43,056-square-foot interior for a Russian owner, which includes a double height atrium with a piano lounge at the top and a vast open-plan main salon below. Sunken LEDs and bright pink and purple neon lights create a modern party vibe in the social areas, which contrast with the elaborate yet more traditional guest suites. A spiral staircase with intricate metal banisters soars through the heart of the yacht. The open stern area has a winter garden (enclosed glasshouse) that allows dining in all seasons. Serene also has two helipads and a hangar, a big swimming pool, and a tender garage large enough for a submarine.

As Far As You Can Sea: World’s Largest Superyachts

Multimillion-dollar mega yachts.

At Luxe Digital, we test and recommend products that we think you will love. If you buy something, we might earn a commission . This supports our team at no extra cost for you.

With onboard swimming pools, cinemas, helicopter landing pads, and spas, the world’s largest superyachts have more facilities than your ‘average’ five-star hotel.

Owned by some of the world’s wealthiest people—along with a few anonymous owners who’d prefer to keep their luxury transport a secret—these mega yachts redefine the word “boat” into something indescribably sleek, stylish, and seriously impressive. 

If superyachts are your thing, you’ll want to read on for all the facts and figures on all of the largest yachts in the world.

Multimillion-dollar mega yachts: Our ranking methodology

A superyacht or mega yacht is typically a motor yacht or sailing yacht with a length of 30 meters (100 feet) or more. For this ranking, we looked at the superyachts and luxury expedition mega yachts that are used privately or made available for charter. We excluded so-called ‘residential superyachts’ (think Njord and The World), which are essentially luxury apartment buildings at sea where people own private residences inside the superyacht rather than the whole yacht. By researching diverse, reliable sources like Wikipedia and the Superyacht Times, we compile a list of the largest yachts in the world.

Curious about other striking superlatives? Check our round-up of the most expensive cars in the world and the most expensive private jets in the world . They are both perfectly good alternatives to owning a yacht. And if you prefer to stay home, we’ve ranked the biggest homes and the most expensive houses in the world to give you some inspiration too.

26. Y721 (aka Koru) | 417 feet—127m

largest super yachts world y721 aka koru by oceanic - Luxe Digital

Ever wonder where Jeff Bezos spends his downtime? As of today, we’re predicting it to be on his $500 million superyacht. Y721—nicknamed Koru—is 127m long. And featuring three sky-high slender masts, Koru is said to be the largest sailing yacht in the world . 

With dark exteriors and natural wooden decks, Koru is inspired by another one of Bezos’ yachts—the Black Pearl. The clean lines and classically curved bow speak to an understated elegance despite the yacht’s mammoth size. While a long line of portals indicates at least 9 guest cabins. In light of all the secrecy surrounding Koru, we doubt Bezos will ever charter her out, but we can still dream.

25. Al Mirqab | 436 feet—133m

largest super yachts world serene al mirqab - Luxe Digital

Adorned with cascading chandeliers and gold accents, Al Mirqab is renowned for its unrivaled interiors. Surrounded by suspended glass artworks, a grand staircase floats throughout the four floors. And inspired by authentic Arabian styles, the magnificent superyacht is reminiscent of a magic carpet ride through the seas . 

Built for the former Prime Minister of Qatar, Peterswerft-Kusch spared no expense in delivering Al Mirqab to an impossibly high standard for luxury. The large swimming pool is a standout feature as it opens up into the sea, creating the ultimate playground for adults. Al Mirqab has a capacity for up to 60 guests and is manned by an equal number of crew. Although you have to be invited by the politician himself as Al Mirqab isn’t available for private charter.

24. Serene | 439 feet—134m

Adeptly named, the magnificent superyacht embodies the serenity of a life at sea. Serene was built in Italy for a Russian owner in 2011. She was leased to Bill Gates for the Summer in 2014 for $5 million per week. 

Designed by Reymond Langton, the 134m mega yacht marries elegant sophistication with state-of-the-art technologies. The seven decks leave ample space for guests to soak in scintillating views. While the underwater viewing room—nicknamed the Nemo room—is a permanent gallery of resplendent sealife. The real-life snow room makes up to four inches of snow. And whilst this may seem odd when your billionaire boss asks for snow—you make it snow.

Yet another Lurssen masterpiece, Crescent pays homage to classic naval designs with traditional architecture and elegant interiors. Formerly named Project Thunder, she was built in Germany and delivered to Igor Sechin in 2018. The Russian oligarch’s superyacht was seized by Spain after sanctions were placed on Russia in 2022. 

Crescent features low bulwarks and full-height windows to maximize the view from the center of the boat. Her distinctive wing station provides unrivaled views for up to 18 guests. But don’t get your hopes up—Crescent is strictly for private use only and isn’t available for charter.

largest yachts savarona - Luxe Digital

Savarona is the second-largest yacht built by Blohm & Voss and spends most of her time in the Mediterranean. This luxury superyacht is one of the oldest in the market — a perfect fusion of traditional charm and modern facilities. 

Previously named Gunes Dil, Savarona was designed by Cox & Stevens, with interior design carefully handled by Donald Starkey. She’s available to charter on a weekly basis and has been refurbished over the years. Back in the day, her cost price was $4 million, and in 1989, she was chartered by Kahraman Sadikoglu, owner of the Turkish Sadikoglu Group, who spent an estimated $50 million on refurbishing her from top to bottom.

21. Flying Fox | 446 feet – 136m

largest yachts flying fox - Luxe Digital

Flying Fox is known as the most expensive charter yacht in the world , and a week aboard will set you back around $3 million. Chartered by the one and only power couple Beyonce and Jay-Z in 2021, it’s filled to the brim with all of the luxury facilities you could ever possibly want. 

The Flying Fox is rumored to be owned by Jeff Bezos, although that’s a claim that’s never been totally certified. She spends most of her time in the Mediterranean, specifically Cannes, Capri, and Sardinia, although she’s recently visited Norway, too. She can accommodate the largest helicopters on the market, and it reportedly took more than 50 meetings with her owner for interior design to be completed.

largest yachts rising sun - Luxe Digital

The Rising Sun’s original owner, Larry Ellison, CEO of Oracle Corporation, sold her in 2010 as he considered her too large. Famously used by David Geffen for self-isolation, Rising Sun has also been a popular hang-out spot for celebrities like Oprah Winfrey and Beatrice, the Princess of York. 

She’s a Superyacht with impressive attention to detail like interiors kitted out in teak and onyx and endless features like a full gym, a large wine cellar, a sauna, and a spa. She’s got a full-size basketball court that doubles up as a helicopter landing pad and a private cinema for those long evenings spent at sea.

19. Al Salamah | 457 feet – 139m

largest yachts al salamah - Luxe Digital

Al Salamah is part of the Omani Royal fleet and started her very secretive life in Genoa. Known as the world’s biggest superyacht right up until 2016, she’s a sleek masterpiece of a ship, with a distinctive cream color and beach club design. 

Al Salamah does everything in multiples, from the five galleys onboard (the main galley, a bakery, a crew galley, an owner’s diet galley, and an Arab galley), three hospitals (one for the owner, one for guests, and one for the crew) and 2,000 sqm of floor space. She was put on sale briefly for $280 million USD, before being delisted and instead given as a gift to the Crown Prince of Bahrain.

18. Solaris | 458 feet – 139m

largest yachts solaris - Luxe Digital

Everything about Solaris was supposed to be kept a secret when she was being built—a secret that didn’t last long when her huge size was spotted undergoing sea trials in the North Sea. One of this Superyacht’s main attractions is her beach club on the top floor: the perfect spot for relaxation during those long days out at sea. 

That beach club comes complemented with endless other stylish amenities, like a large helipad, sun deck, and a crane to launch tenders, toys, and subs. Interior design is largely unknown, but, if it’s anything as sleek and white as its exteriors, it’s sure to be impressive.

largest yachts scheherazade - Luxe Digital

Two helicopter landing pads, two outdoor Jacuzzis, and two outdoor fire pits: Scheherazade doesn’t hold back with not only the essentials but also the luxuries. Previously named Lightning, “Scheherazade” is mostly associated with a female character in the Middle Eastern folk tales in the series One Thousand and One Nights. 

Not much is known about this superyacht, and even her birth and building process were referred to under a codename: Project Lightning. No one involved in her creation, even Lurssen, has revealed anything about her interiors or her owner. All that’s really known is that she sailed from Germany to Norway initially after completion.

largest yachts ocean victory - Luxe Digital

Ocean Victory has traveled all over the world, from Europe to Southeast Asia and back again. Owned by Russian billionaire Viktor Rashnikov, she’s the upgraded vessel to follow his purchase of the 76-meter Ebony Shine. 

She’s one designed with pure luxury in mind, from the six individual swimming pools onboard to the 300-square meter spa area. She’s beautiful both inside and out, with a unique concept designed by Espen Oeino and interior designer Alberto Pinto. The largest superyacht ever built in Italy, Ocean Victory shows some of the finest in the world when it comes to premium quality adventures at sea.

15. Yas | 463 feet – 141m

largest yachts yas - Luxe Digital

Yas is known best for its seamless and rather unusual design — one that’s a little different from most superyachts out there. The owner of Yas wanted a yacht that lived up to his own heritage; one with a backbone reminiscent of the navy and with abstract lines throughout. 

He chose an existing boat in Abu Dhabi, which was deconstructed within the region before being shipped off and renovated into the wonder that it is today. The Yas yacht was originally a Dutch navy frigate, which you’d never guess from strolling around onboard today.

14. Nord | 465 feet – 142m

largest yachts nord - Luxe Digital

Nord’s distinctive bow design has never been seen before on a yacht. That’s one of the first things you’ll notice about her. The next thing you’ll notice is her unusual design, which verges on battle-esque and has been called “ a warship wearing a tuxedo ” by Dan Lenard of the Italian design studio Nuvolari-Lenard. 

She’s one of the best superyachts out there for fun, with a sports and diving center on the lower deck, a swimming pool higher up, overlooking the ocean, and a fleet of tenders. She was designed for global exploration: a yacht that will calmly cruise her way all across the world.

13. Sailing Yacht A | 469 feet—142.8m

Challenging the status quo and pushing design boundaries, Sailing Yacht A is an enigma. The sail-assisted superyacht was built in Germany and delivered to Russian tycoon Andrey Melnichenko in 2017. However, she was seized by the Italian police force, Guardia di Finanza, in 2022 after sanctions were placed on Russian businessmen following Russia’s invasion of Ukraine. 

Distinguished by soaring rotating carbon fiber masts, Nobiskrug’s hybrid approach to superyachts makes Sailing Yacht A more eco-conscious than other luxury yachts of her size. The u nderwater viewing pod molded into the keel speaks to her unrivaled innovation. And many balconies are enclosed by some of the largest pieces of curved glass ever made.

largest yachts el mahrousa - Luxe Digital

El Mahrousa had a few different names in her time, ranging from the translated “The Protected” to El Horreya, which in Arabic translates to “Freedom.” It’s not surprising that she’s had more than one name when you take into account her age. As the oldest superyacht in the world, she’s undergone a lot of restoration over time, including multiple lengthenings and faster engines. 

She was renamed back to El Mahrousa in 2000 and gained even more recognition for being the first ship to cross the new Suez Canal extension in 2015. Back in her original days, she was built on the River Thames and took her first trip in 1867.

11. OK | 479 feet—146m

largest yachts ok - Luxe Digital

Delivered in Japan in 1982, OK is one of the largest and most unique superyachts in the world. Sprawling over 479 feet, the water giant is engineered to submerge almost seventy percent. This is accredited to the work done by Karmarine Shipyard. While the majority of the vessel was built by Oshima Shipping, it was privately converted to a semi-submersible yacht in Turkey. 

The superlative finishing on OK superyacht was designed by Timur Bozca, winner of the Younger Designer of the Year award in 2015. The blueprint being as many games as possible. The extraordinary vessel has the uncanny ability to hold over seventy toys, including a sailing yacht, a sea plane, tenders, buggies and even a tennis court.

10. Opera | 480 feet—146.4m 

largest yachts opera - Luxe Digital

Like many of the most majestic water titans, Opera was delivered by Lurssen in Germany and built for Abu Dhabi royalty. This time, the owner is Sheikh Abdullah bin Zayed Al Nahyan, son of the founder of the United Arab Emirates. And while it may not be quite as astronomical as Lurssen’s previous builds—Azzam, Blue and Dilbar—the streamlined vessel is equally impressive onboard. 

The three-story superyacht proves large enough for a pair of helipads and two swimming pools, amongst many other toys, while simultaneously making room for up to 48 guests and 80 crew members. When it comes to the interior, details are sparse, but we do know that it was designed by Terence Disdale, a London firm renowned for creating bespoke luxury spaces.

largest yachts prince abdulaziz - Luxe Digital

The Prince Abdulaziz’s yacht was ordered by King Fahd, who named her after his son Prince Abdul Aziz. Now, she’s owned by his brother, Abdullah. Just one of the yachts owned by the Saudi royal family, she’s spotted frequently throughout Europe, especially in Cannes, where the royal family owns a property. 

She’s been redecorated once — in 2007 — in a project that took 15 months to complete, without even taking into account the rest of the ship’s upkeep. The Prince Abdulaziz is known for its combination of bold colors and fusion of traditional and modern design, thanks to its influence from the late David Hicks.

largest yachts a plus - Luxe Digital

What do you do when the name “A” is already taken for your superyacht? Choose the next closest thing: A+. Previously named Topaz, this superyacht was the world’s fourth-largest luxury yacht when she was built, before being stripped of that particular title only a few years later. 

Nevertheless, she’s a seriously impressive superyacht, with endless facilities like a large jacuzzi, double helicopter landing pads, a swimming pool with a swimming platform and underwater lights, as well as a fitness hall, cinema, and a large conference room. She’s also well equipped with water toys, like jet skis, inflatable boats, a catamaran, and even a mini-submarine.

Another Superyacht built, shrouded in secrecy, Al-Said was referred to as “Project Sunflower” the entire time she was being created, right up until she was delivered to her owner in 2008. Not much is known about Al Said, from her movements through to her amenities — although she is known to have a huge concert room with space for a full 50-person orchestra. 

Currently, she’s flying the flag of Oman and has spent a lot of time in its surrounding waters. Her interior was styled by British designer design house RWD, with exterior design being credited to Espen Oeino. When she was delivered to the Sultan of Oman, she replaced a previous ship of a smaller size.

Dilbar, or Project Omar, as it was originally known as, is another superyacht designed with the help of exterior expert Espen Oeino, but with interiors strikingly designed by Andrew Winch. Dilbar is famously known as the world’s largest yacht by gross tonnage (interior volume) but as the fifth-longest superyacht in the world. 

She’s home to a spa pool and beach club, as well as a large private cinema, spacious cabins set high on the main deck, a spacious dining room, and a salon with its own piano. She’s just as classy and beautiful on the inside as she is on the outside.

Sunday blues simply cease to exist on one of the world’s most extravagant superyachts. The elegant behemoth was built for member of the ruling family of Abu Dhabi and billionaire, Sheikh Mansour bin Zayed Al Nahyan in 2022. Valued at over $600 million, Blue is one of the most expensive superyachts in the world. And with a strong emphasis on the environment, this superyacht is also one of the most sustainable. 

Blue strives to be as environmentally friendly as possible. She is equipped with a highly efficient Diesel-Electric Hybrid Propulsion Concept developed by Lürssen’s own engineering specialists. And the wastewater treatment plant allows water to be disposed of in drinking water quality.

4. Dubai | 531 feet – 162m

Dubai had multiple names in the planning stages—including Panhandle, Platinum, and Golden Star. Owned by the ruler of Dubai, it was aptly named after its home country and comes with all of the luxurious amenities you’d expect from such a name. 

The Dubai comes complete with a huge swimming pool and two jacuzzis. Further down, you’ll find a large dining room with striking blue and burgundy decor and space for up to 90 guests. Dubai usually spends her time moored at Sheikh Mohammed’s private island in front of his summer palace in Dubai. She’s basically the definition of a floating palace.

3. Eclipse | 533 feet – 162.5m

largest yachts eclipse - Luxe Digital

It took around five years for Eclipse to be built from start to finish. While she was always designed to be a huge, luxurious Superyacht, the focus was more on decking it out appropriately rather than breaking any records. An award-winning superyacht, she’s incredibly spacious, with endless rooms to explore and a sleek, neutral color palette running through. 

The Eclipse’s owner, Roman Abramovich, was more focused on facilities: he wanted more than one helicopter pad and a large swimming pool, too. Other than that, designer Terry Disdale had free reign for the rest of the superyacht. It’s just as much a clean piece of architectural styling as it is a stunning experience on deck.

2. Fulk Al Salamah | 538 feet – 164m

largest yachts fulk al salamah - Luxe Digital

Fulk Al Salamah translates to “Ship of Peace” and that’s something that sounds like a given when you’ve taken a look at this superyacht’s incredible layout. Developed under the codename Project Saffron, Fulk Al Salamah is more of a support vessel than she is a typical superyacht. 

While she might still come complete with all of the necessities for a particularly relaxing voyage, she’s more so known for being a transport ship for the Royal Navy of Oman. She’s also used as a sort of friendship boat — pun intended — and is often sailed across the world with the intention of strengthening ties with the Sultanate. In some ports, influential people are welcomed onboard.

1. Azzam | 590 feet – 181m

largest yachts azzam - Luxe Digital

Most superyachts in the top 10 category have a few mere inches between sizes, but the Azzam shoots far ahead with a large amount of extra length. The largest superyacht in the world, she was never designed to win the title — rather just to be a sleek and elegant vessel. Azzam was crafted backward, with the plans for her interior confirmed long before her exterior was fully signed off. 

Her length only came to be as such to incorporate everything required for the interiors, which added an extra 35 meters to her overall size. She’s also designed to look smaller than she actually is, with a blend of indoor and outdoor living. It took more than 4,000 people to build Azzam , clocking up six million man-hours over a period of four years.

The most expensive yacht in the world

The fact that the History Supreme, the world’s most expensive superyacht, comes coated in gold, is only part of the reason for its high cost. A superyacht with a real-life Midas touch, it was sold to an anonymous Malaysian businessman for $4.8 billion. 

Robert Kuok, the richest Malaysian businessman, is the rumored owner of History Supreme, but no one has confirmed for sure. The History Supreme also comes with plenty of other impressive touches: a master bedroom decked out in platinum, a wall feature made from meteoric stone, and a genuine T-Rex dinosaur bone, to add to the list. 

She took three years to build from scratch and comes with 10,000 kilograms of solid gold and platinum. Other seriously luxe features are her 68 kilograms 24-carat gold Aquavista Panoramic Wall Aquarium and a liquor bottle adorned with a rare 18.5-carat diamond . The base of the vessel comes wrapped in gold, too.

One of the newest ships on this list, Crescent was built by Lurssen in 2018 and is just less than 445 feet long. This sleek ship's exteriors were designed by French yacht design firm Zuretti and its interiors by Monaco's Espen Oenio. It can house up to 18 guests and 24 crew and features a two-level glass atrium, a helicopter hangar, and a glass-bottomed pool.

Prince Abdulaziz

This stunning megayacht is part of the Saudi family's royal fleet of yachts. It was built in 1984 at 482 feet, making it the largest yacht built in the 20th century, and held the spot as world's largest until Dubai was launched in 2006. Its interiors took 15 months alone to craft under the direction of the one-and-only David Hicks, who designed the space to suit 64 guests and 65 crew. The yacht is used for both business and pleasure and is rumored to house missiles and an underwater surveillance system.

This 416-foot megayacht was the passion project of Microsoft's cofounder Paul Allen and is currently owned by his wife, Jody Allen. The groundbreaking exploration yacht has the ability to travel to the world's mot remote and otherwise inaccessible locations. It was built by Lurssen in 2013 with exterior design by Espen Oenio and interiors by Seattle-based yacht designer Jonathan Quinn Barnett, housing 26 guests and 63 crew. A spa, library, multiple lounges, alfresco dining spaces, and a basketball court are just the beginning of Octopus's array of amenities.

Al Mirqab was built in 2008 by Peters Schiffbau and is owned by Sheikh Hamad bin Jassim bin Jaber Al Thani, who is Qatar royalty, a businessman, and a politician. Its exteriors were designed by Kusch Yachts and its award-winning interiors by Winch Design. Al Mirqab measures 437 feet and houses up to 60 guests and crew each. The yacht features a grand staircase with sides made from hand-cut crystal panels, cinema, spa, beach club and a lower deck swimming pool that can be opened up to the sea.

Launched in 2012, the yacht formerly known as Topaz stretches 483.1 feet long and reaches speeds up to 19.5 knots. And with interiors by the renowned Terrence Disdale , you know this behemoth is as spectacular on the inside as its exterior. It’s equipped with an on-deck Jacuzzi, double helicopter landing pad, swimming pool, fitness center, cinema room, and a snazzy conference room. A+ is reportedly owned by Sheikh Mansour, deputy prime minister of the UAE, and can accommodate up to 62 guests and 79 crew members.

One of the world’s largest “gigayachts”—measuring a whopping 456 feet—is also one of the newest, as it is currently undergoing trials in the Baltic Sea. This sleek structure, formerly known as Opus and Project Redwood, technically launched in January 2019 but came back to Lurssen for more fine tuning and upscale additions. The interiors and exterior are both by Nuvolari Lenard , and the yacht will reportedly sleep up to 36 guests. Some of the ultra-fabulous amenities include a beach club, fitness center, spa and sauna, Jacuzzi, swimming pool, elevator, two helipads, and an impressive study.

Katara was launched in 2010 and measures 408.2 feet long and reaches speeds up to 20 knots. The yacht’s interiors were reportedly done by Alberto Pinto and comfortably accommodate 34 guests and 95 crew members. Much of Katara remains a mystery, but we do know it belongs to either the former Emir of Qatar, Sheikh Hamad bin Khalifa al Thani, or Sheikh Nawaf bin Jassim Bin Jabor Al-Thani, chairman of the Katara Hospitality Group, and docks in the city of Dohu. Katara also reportedly has its own beach club with sea terraces.

Savarona is the oldest yacht on this list, as it was originally launched in 1931 and refitted in 1999. The 446-foot yacht boasts interiors by Donald Starkey, room to sleep 34 guests and 48 crew, and luxe amenities, like ample spa facilities, a spacious study, oversize media room, and plenty of fabulous deck space for lounging.

This sleek yacht belongs to Roman Abramovich, billionaire businessman, politician, and owner of the Chelsea Football Club. Some of the likely amenities on board include a three-person submarine, a 52-foot pool that can be converted into a dance floor, and an exterior fireplace. Eclipse is believed to accommodate 36 guests and 70 crew members.

Eclipse Yacht Interior

Eclipse 's interiors were designed by world-renowned Terence Disdale Design in London.

Dilbar is owned by Russian billionaire Alisher Usmanov and is considered the largest yacht in the world by gross tonnage and interior volume. Usmanov named this Lurssen masterpiece after his mother. Some of this boat’s amenities include a 82-foot indoor swimming pool, sauna and massage room, movie theater, and underwater lights. Dilbar accommodates 40 guests and 80 crew members.

Dilbar Yacht Interior

Andrew Winch of Winch Design Group , a London-based design group for luxury homes, yachts, and planes, designed the interiors of Dilbar .

The 590-foot Azzam is considered the longest yacht in the world and is reportedly owned by the royal family of Abu Dhabi. Built in 2013, this Larsson yacht made yachting history for not only its size, but its ability to reach top speeds of more than 30 knots.

French designer Christophe Leoni spearheaded the interior design of this boat that accommodates 36 guests and 60 crew members.

This megayacht was constructed by Platinum Yachts for Prince Jefri Bolkiah of Brunei and now belongs to Sheikh Mohammed bin Rashid Al Maktoum, ruler of Dubai and Prime Minister of the United Arab Emirates. The yacht took 10 years to perfect and is widely considered one of the most luxurious yachts in the world. Dubai boasts a mosaic-tiled swimming pool, multiple Jacuzzis, disco, and a squash court. Its dining room alone can hold up to 90 guests, and the boat has room for 88 crew members.

Dubai Yacht Interior

The interiors of Dubai were designed by Andrew Winch of Winch Design .

Fulk Al Salamah

Fulk Al Samanah was assembled by Mariotti in Genoa, Italy, and is the world's second-largest superyacht. It is believed to belong to the Omani Royal Fleet. Notable amenities include a beauty salon, beach club, and conference facilities, and it requires 130 crew members for optimal ventures. Little information about the Fulk Al Samanah is known, but the boat's exterior was designed by Studio de Jorio.

This stunner belongs to billionaire and entertainment mogul David Geffen and has likely hosted a favorite celebrity (or 10) of yours over the past few years—even the Obamas. Complete with a gym, sauna, pool, and underwater lights, what more could you ask for in a party venue? This Lurssen yacht holds 18 guests overnight and up to 45 crew.

Rising Sun Yacht Interior

There isn't much out there about the interiors of Geffen's yacht, but we do know it was designed by Bannenberg and Rowell .

Ocean Victory

Ocean Victory was built in 2014 by Fincantieri and is owned by Russian billionaire Viktor Rashnikov. It holds 26 guests and 50 crew. Notable amenities include six pools, a beach club, and an underwater observation room.

Little is known about the interiors of this ship, except that it was designed by Alberto Pinto and Laura Sessa Romboli, so you know it has to be absolutely fabulous.

Top 10 Largest Yachts In The World 2021

Discover the world’s biggest superyachts..

Breaking records is cool. Especially when it has to do with building the biggest, longest, tallest, largest superyachts in the world. Technically speaking, each of those superlatives has its own category when it comes to shipbuilding. Number 2 on this list is *technically* bigger than number 1, which is longer. And one of the yachts on this list holds the title of oldest while also being one of the largest. It gets confusing, but when you’re building boats for people who want to break records, it matters.

Think you’ve seen a big superyacht? Think again. Here are the 10 largest yachts in the world for 2021. When yachts get this big, it can be difficult to discern a cruise ship from a superyacht.

10. SAILING YACHT A | 142 Meter (468 Foot) Nobiskrug 2017

largest mega yacht in the world

Zoom into the future — SAILING YACHT A is the largest private sail-assisted motor yacht in the world. At 468 feet and built by Nobiskrug in 2017. She’s an advanced superyacht with unique features such as an underwater observation pod, a hybrid diesel-electric propulsion system, and state-of-the-art navigation systems.

The luxury sailing yacht’s three masts are the tallest and the most highly loaded freestanding composite structures in the world. The nearly invisible windows give this yacht a futuristic look offering no peep into the interior, which is still a mystery. SAILING YACHT A is owned by Russian billionaire Andrey Melnichenko.

9. EL MAHROUSA | 145 Meter (478 Foot) Samuda Brothers 1865

largest mega yacht in the world

Fresh out of the history and record books is EL MAHROUSA, a 478-foot Samuda Brothers yacht launched in 1865 (erm, yeah you read that right). This yacht was built for the Ottoman governor of Egypt and even made an appearance at the opening of the Suez Canal in 1869 (thankfully it never got stuck in the canal).

Of course, she underwent plenty of refits over the years, including the replacement of its paddle wheel engines by turbine-driven propellers in 1905. It also had a telegraph installed in 1912. EL MAHROUSA was also lengthened by 40 feet in 1872 and another 17 feet in 1905. The yacht is currently in the care of the Egyptian Navy and occasionally used as the Presidential Yacht. It is the oldest active superyacht in the world and the ninth largest one.

8. PRINCE ABDULAZIZ | 147 Meter (482 Foot) Helsingor Vaerft 1984

largest mega yacht in the world

PRINCE ABDULAZIZ is a 147- meter motor yacht built by Helsingor Vaerft and delivered in 1984. For many years, it was the world’s largest yacht in terms of length and height. It’s one of the royal yachts of the Saudi royal family, originally owned by King Fahd. Although its interior was designed by the late David Nightingale Hicks, you’re not going to find any pictures of it. All we know is that it’s as luxurious as the TITANIC.

7. A+ | 147 Meter (482 Foot) Lürssen 2012

This image has an empty alt attribute; its file name is 7.png

The seventh-largest yacht in the world is A+ (formally known as TOPAZ) at 147 meters long. With her gross tonnage of 12,532 GT, A+ is also one of the world’s largest superyachts in terms of volume. This 2012 Lürssen superyacht is reportedly owned by Sheikh Mansour Bin Zayed Al Nahyan, owner of Manchester City Football Club and Emirate royalty.

This 8 deck vessel features 2 helipads, a gym, 2 Jacuzzis, a movie theatre, and a conference room. While not much is revealed about the Terence Disdale styled interior, A+ can accommodate up to 62 guests in 26 cabins, along with 79 crew members.

6. AL SAID | 155 Meter (508 Foot) Lürrsen 2007

This image has an empty alt attribute; its file name is 6.png

At 509 feet long, AL SAID is the sixth-largest superyacht in the world. It was launched by Lürssen in 2007 and resembles a classic cruise liner. At its widest point, the ship measures nearly 79 feet across. It is owned by the Sultan of Oman and can supposedly accommodate 70 guests and up to 154 professional crewmembers. The vessel features 6 decks and a concert hall big enough for a 50 piece orchestra.

5. DILBAR | 156 Meter (511 Foot) Lürrsen 2016

This image has an empty alt attribute; its file name is 5.png

DILBAR is a 156-meter superyacht built by Lürssen in 2016. Her exterior was designed by Espen Øino, who created a classic profile with a light ivory hull. Her interior design is said to be decorated in rare and exclusive luxury materials by Winch Design, but additional details and photos are not made public.

At 15,917 tons and 156-meters long, Lürssen announced that DILBAR is one of the most complex and challenging yachts ever built, in terms of dimensions and technology. Her features include a 25-meter swimming pool (the largest ever installed on a yacht) and 2 helipads. It’s owned by one of Russia’s richest men , Alisher Usmanov.

4. DUBAI | 162 Meter (532 Foot) Platinum Yachts 2006

This image has an empty alt attribute; its file name is 4.png

Make room for DUBAI , a 161-meter yacht with a nonlinear build history. This superyacht was originally a joint project between Blohm+Voss and Lürssen in 1998. But the project was halted with a skeletal superstructure.

The hull was sold to the government of Dubai, and the project began again under the direction of the new owner, Sheikh Mohammed bin Rashid Al Maktoum (ruler of Dubai), and Platinum Yachts. The yacht was finished in 2006. Some of its stand-out features include 7 decks, helipad, submarine garage, nightclub, cinema, and 70-foot-wide atrium. DUBAI can accommodate 24 guests.

3. ECLIPSE | 162 Meter (531 Foot) Blohm+Voss 2010

largest mega yacht in the world

By the time it left the Blohm+Voss German shipyard in 2010, ECLIPSE was the largest superyacht in the world. Today, it’s been knocked down a few pegs at 162 meters in length. It’s owned by Russian businessman, Roman Abramovich. ECLIPSE boasts 18 staterooms and can accommodate 36 guests.

At the time of its launch, it hosted the largest swimming pool (with adjustable depth to become a dance floor) onboard a yacht at 16 meters long. This luxury yacht has interesting features including a missile detection system (you know, just in case), bulletproof windows (again, just in case), a submarine, three helicopters, six tenders, spa, gym, and beach club. It’s currently valued at $1.2 billion and considered the world’s most expensive yacht .

2. FULK AL SALAMAH | 164 Meter (538 Foot) Mariotti 2016

This image has an empty alt attribute; its file name is 2-1.png

FULK AL SALAMAH , translated to Ship of Peace, is a 164-meter Mariotti mega yacht built in 2016. This monster of a yacht is believed to be owned by the Omani royal family. Although, not the longest yacht, she is the biggest in terms of volume at 22,000 gross tonnage. The exterior design is by Studio de Jorio and resembles more of a cruise ship than a private superyacht. Not many details are revealed about FULK AL SALAMAH as this project and delivery has been kept under wraps from its beginning.

1. AZZAM | 180 Meter (590 Foot) Lürssen 2013

largest mega yacht in the world

At a whopping 180 meters in length, AZZAM is the longest private yacht in the world. This superyacht was launched in 2013 by Lürssen Yachts, and currently owned by Sheikh Khalifa bin Zayed Al Nahyan, President of the United Arab Emirates and Ruler of Abu Dhabi. It cost more than $600 million to build.

AZZAM has a beam of 20.8 meters (68 feet) and an unusually shallow draft of 4.3 meters (14 feet). Exterior designer, Nauta Design created this vessel to be sleek and timeless while appearing smaller than her size. The 9,000kW MTU engines give her a speed of 18 knots over long distances, with a top speed of 33 knots.

As the longest private yacht in the world, AZZAM can accommodate 36 guests and up to 80 crew. The interior style is largely a secret, but it’s rumored that some of the wood furniture onboard is intricately veneered with mother of pearl marquetry. Other onboard features include a gym, pool, and golf training room.

While these top 10 largest yachts in the world may seem out of reach, let’s bring it down to earth and explore Denison’s featured listings .

Video shows moments before superyacht went down in storm off Sicily

Newly released video captures a luxury superyacht being battered by a violent storm before it suddenly sank off Sicily with 22 people aboard Monday.

The grainy images obtained by NBC News and other outlets were recorded on closed-circuit television not far from where the Bayesian was anchored, about a half-mile from the port of Porticello, on Sicily’s northern coast .

The yacht's 250-foot mast, illuminated with lights and lashed by the storm, appears to bend to one side before it finally disappears and is replaced by darkness.

The speed with which a yacht built to handle the roughest seas capsized stunned maritime experts.  

“I can’t remember the last time I read about a vessel going down quickly like that, you know, completely capsizing and going down that quickly, a vessel of that nature, a yacht of that size,” said Stephen Richter of SAR Marine Consulting.

British tech tycoon Mike Lynch and five of the 22 other people who were aboard the 184-foot vessel remain unaccounted for and are believed to be trapped in the Bayesian’s hull, nearly 170 feet underwater.

Officials confirmed Monday that at least one person, the ship’s cook, had died.  

UK's vessel Bayesian

Superyachts like the Bayesian, which had been available for charters at a rate of $215,000 a week, are designed to stay afloat even as they are taking on water to give the people aboard a chance to escape, Richter said. 

“Boats of this size, they’re taking passengers on an excursion or a holiday,” Richter said. “They are not going to put them in situations where it may be dangerous or it may be uncomfortable, so this storm that popped up was obviously an anomaly. These vessels that carry passengers, they’re typically very well-maintained, very well-appointed.”

Built by Italian shipbuilder Perini Navi in 2008, the U.K.-registered Bayesian could carry 12 guests and a crew of up to 10, according to online specialist yacht sites. Its nearly 250-foot mast is the tallest aluminum sailing mast in the world, according to CharterWorld Luxury Yacht Charters. 

On Tuesday, Italian rescue workers resumed the search for Lynch and the five other passengers still missing: Lynch’s 18-year-old daughter, Hannah; Morgan Stanley International Chairman Jonathan Bloomer and his wife; and Clifford Chance lawyer Chris Morvillo and his wife.

“The fear is that the bodies got trapped inside the vessel,” Salvatore Cocina, the head of civil protection in Sicily, told Reuters .

The Bayesian is owned by a firm linked to Lynch’s wife, Angela Bacares, who was one of the 15 people rescued Monday after it capsized.

“It’s extremely rare for a boat of this size to sink,” Richter said.

What’s not rare is the kind of storm that sank it , said Simon Boxall, senior lecturer in oceanography at Britain’s University of Southampton.

“People assume the Mediterranean is this rather calm and passive place that never gets storms and always blue skies,” Boxall said. “In fact, you get some quite horrendous storms that are not uncommon at this time of year.”

The president of Italy’s meteorological society has said Monday’s violent storm may have involved a waterspout, essentially a tornado over water, or a downburst, which occurs more frequently but doesn’t involve the rotation of the air.

Luca Mercalli, president of the Italian Meteorology Society, also said recent temperatures may have been a factor. 

“The sea surface temperature around Sicily was around 30 degrees Celsius [86 Fahrenheit], which is almost 3 degrees more than normal,” Mercalli told Reuters. “This creates an enormous source of energy that contributes to these storms.”

The Mediterranean sailing vacation was designed to be a celebration for Lynch, who two months ago was acquitted by a San Francisco jury of fraud charges stemming from the 2011 sale of his software company Autonomy to Hewlett-Packard for $11 billion.

Prosecutors alleged that Lynch, dubbed “Britain’s Bill Gates,” and Autonomy’s vice president for finance, Stephen Chamberlain, had padded the firm’s finances ahead of the sale. Lynch’s lawyers argued that HP was so eager to acquire Autonomy that it failed to adequately check the books .

Lynch had taken Morvill, who was one of his defense attorneys, on the luxury trip. 

Chamberlain was not on the Bayesian.

In what appears to be a tragic coincidence, a car struck and killed Chamberlain on Saturday as he was jogging in a village about 68 miles north of London, local police said.

“Steve fought successfully to clear his good name at trial earlier this year, and his good name now lives on through his wonderful family,” Chamberlain’s lawyer, Gary Lincenberg, said in a statement .

The 10 biggest superyachts currently listed for sale

Related articles, superyacht directory.

Want to know how much boat you can buy for your buck? BOAT takes a look at the biggest yachts currently for sale, starting with the iconic 114.5-metre superyacht Pelorus ...

Pelorus | 114.5m

Year: 2003 Builder: Lürssen

Pelorus was commissioned by a Saudi businessman who enjoyed one long, glorious cruise aboard his new superyacht before tycoon Roman Abramovich made him an offer too good to refuse. Easily the largest yacht to be built by Lürssen at the time, her Tim Heywood exterior features a top deck "lido" with two swimming pools, two helicopter pads and a vast, sea-level platform revealed by opening the transom. Interiors were carried out by Terence Disdale , who opted to use natural materials wherever possible to maintain a "casual" atmosphere – in the hopes it would offset the yacht’s imposing frame.

Pelorus is asking €185,000,000 with Burgess .

Moonlight II | 91.4m

Year: 2005 Builder: Neorion

The brainchild of the late Andreas Liveras, Moonchild II was originally commissioned as the 85.3-metre Alysia alongside sistership Annaliesse (now Queen Miri ). Her transformative 2015 refit added the extra 6.1 metres alongside a brand new beach club made complete with a well-stocked bar, sunbathing areas and shell doors that reveal far-flung ocean views. Other highlights include a touch-and-go helipad and a full-beam spa with massage room, beauty salon, steam shower and gym.

Moonlight II is asking €68,000,000 with Fraser .

Phoenix II | 90.1m

Year: 2010 Builder: Lürssen

Phoenix II  takes a page (or two) from The Great Gatsby with her cherry velvet flooring and gilded details. The owner commissioned Winch Design to create her intricate "Art Deco meets the New York skyline" design concept, including a 5.7-metre phoenix figurehead modelled after the Chrysler building's mounted eagles. Roaring highlights include a sommelier room, three swimming pools, a plush cinema room and a custom Steinway for some musical accompaniment at mealtimes.

Phoenix II is asking €124,950,000 with   Cecil Wright and Burgess .

Lady Lara | 91m

Year: 2015 Builder: Lürssen

Debuting on the brokerage market in September 2023, Lady Lara has eluded the public eye for eight years – with BOAT International only recently stepping on board . She was designed inside and out by Reymond Langton and features two standout swimming pools . The first transforms into a dance floor with surround-sound while the second is fitted with a swim-up bar, large day bed and sunlounger. Lady Lara 's recently-completed winter works were valued at a staggering €15,000,000.

Lady Lara is asking €230,000,000 with Y.CO and Merle Wood & Associates .

Year: 2009 Builder: Abeking & Rasmussen

Another Reymond Langton entry, B2 remains the second-largest launch by the German shipyard (beaten out by the 118.2-metre Livao ). Her recent four-million-euro refit saw the hull extended by seven metres – allowing room for a spacious beach club, with a glass-bottom infinity pool acting as its rippling, refracted ceiling. The beach club is also outfitted with lounge chairs, a drinks bar and flatscreen television.

B2 is asking €79,000,000 with Moravia Yachting .

Chakra | 86m

Year: 1963 Builder: Van Der Werf

Delivered first as a commercial vessel, Chakra was converted into a full-fledged superyacht in 1998 by Devonport Yachts . The change saw her five decks rearranged with a dedicated yoga area, spa pool, beauty parlor, massage room and gym. This unconventional yacht also boasts a globe-trotting range (in exces of 10,000 nautical miles) and a spacious tender garage housing Yamaha Wave Runners, two RIBs and a 12-metre Sessa dayboat.

Chakra is listed for sale with Merle Wood & Associates, with POA.

O'Ptasia | 84.7m

Year: 2018 Builder: Golden Yachts

Superseded by 95-metre sistership O'Pari in 2020, Golden Yachts' former flagship is still one of the largest yachts on the market today. Her most attention-pulling feature is the beach club spa, fitted with a steam room, dry Finnish sauna, Hammam and massage room. Continuing the theme of wellness, a touch-and-go helipad on the foredeck can double as a yoga studio (with a view like no other) while her waterfall Jacuzzi is also a rejuvenating spot.

O'Ptasia is asking €89,999,000.00 with Burgess.

largest mega yacht in the world

  • Lurssen Yachts

Developed by German shipyard Lürssen, construction of Project Luminance is underway at their facilities near Lemwerder. Due to enter the esteemed list of the Top 10 largest superyachts in the world, information about the 145m superyacht is limited at this moment in time. Lürssen are world-famous for their incredible innovations and their capacity to build extremely large mega yachts filled with numerous features. Photos that have been captured of the boat indicate that she will have considerable deck space with plenty of room left over indoors to be packed out with luxury.

With a length of 125m, KORU is not just the largest sailing yacht delivered by Oceanco; she is the largest sailing yacht in the world. Taking her righteous place on the Top 100 list, this three-master schooner is an iconic vessel on the sea, bearing a midnight blue hull and extraordinary amount of deck space.

Project JAG, launched in 2023, was sold in 2019 at the Monaco Yacht Show and was first seen 2021, in which her hull and superstructure were revealed. Since then, she has been a highly anticipated launch from Lürssen. She is an impressive build with a LOA of 122m, with exterior design by Nuvolari Lenard and interiors penned by Reymond Langton. She has a sleek and sophisticated profile, with monochromatic black and white tones accented with splashes of red; an eye-catching launch at the Schacht-Audorf facility. Project JAG can accomodate up to 20 guests across 11 staterooms, taken care by a crew of 40, ensuring the ultimate luxury experience. She has a beam of 17.8m, boasting exceptional space on board, so guests can have the most comfortable experience possible.

RENAISSANCE

  • Freire Shipyard

Previously known as NB-724, Freire Shipyard's RENAISSANCE was successfully delivered in 2023. She is a 112m superyacht, able to accommodate 36 guests across six decks. She marks an historical milestone for Freire Shipyard, as she is the largest and highest tonnage yacht built in Spain to date, weighing 7,200 GT.

Sold in 2018 by Moran Yacht & Ship, SHACKLETON, previously known as Project ICECAP, is a 107m motor yacht who is said to be equipped with state-of-the-art technology in particular reference to energy saving and diesel electric propulsion.

How safe are luxury yachts? What to know after Mike Lynch yacht disaster left 7 dead

Portrait of Cybele Mayes-Osterman

The Bayesian was a world-class yacht.

The 19th largest yacht designed by luxury Italian manufacturer Perini , it boasted a sleek interior design by French designer Remi Tessier, a double engine, and one of the tallest aluminum masts in the world. It won multiple awards, including for "best sailing yacht" the year after its release.

But, almost two weeks ago on Aug. 19, the luxurious vessel sank to the bottom of the ocean off the coast of Sicily in an internationally-followed disaster, dumping 22 people aboard into the water and leaving seven dead , including British tech magnate Mike Lynch and his 18-year-old daughter Hannah .

"The impossible happened on that boat," Giovanni Costantino, the yacht manufacturer's CEO, told Reuters.

In the wake of the disaster, an ongoing investigation into possible criminal errors committed by the Bayesian's crew and lingering questions surrounding its design underscore the need for proper yacht safety measures and practical ship designs, according to experts.

Italian prosecutors from a nearby town have now widened their investigation into possible criminal actions by the ship's captain in the lead-up to the shipwreck to include two additional crew members, a judicial source told Reuters on Wednesday.

Tim Parker Eaton and Matthew Griffith are now under investigation for manslaughter and shipwreck, days after news broke that investigators are probing whether Captain James Cutfield committed the same crimes.

Authorities are looking into whether Parker Eaton, a ship engineer, failed to protect the ship's engine room and operating systems. Griffith, a sailor on the ship, was on watch duty on the morning the ship sank.

Cutfield "exercised his right to remain silent" when investigators interrogated him on Tuesday, Giovanni Rizzuti, his lawyer, told Reuters.

"First, he's very worn out," Rizzuti said. "Second, we were appointed only on Monday, and for a thorough and correct defense case, we need to acquire a set of data that at the moment we don't have."

Rizzuti did not immediately respond to a request for comment emailed to him by USA TODAY.

Rescuers found the bodies of Chris Morvillo, an American citizen and lawyer for Clifford Chance, his wife, Neda Morvillo, Jonathan Bloomer, a non-executive chair of Morgan Stanley International, and his wife, Judy Bloomer, inside the ship two days after the wreck. Recaldo Thomas, the ship's cook who also went by Ricardo, was the first person pronounced dead in the disaster – his body was recovered on the day of the sinking.

Captains must follow safety procedures before storms

Costantino chalked up the boat's fate to a "series of indescribable, unreasonable errors" committed by the crew. The ship's crew made an "incredible mistake" in not preparing adequately for the storm, he said.

Costantino said the crew should have summoned passengers from their rooms earlier, as the storm picked up. The keel, a heavy weight under the ship to counterbalance the ship's large mast, should have been lowered, and portholes should have been closed – both factors that could influence whether the captain is found culpable, according to experts .

Captains should always check weather forecasts and look into local weather patterns, Mitchell Stoller, a maritime expert witness and captain, told USA TODAY . When in stormy weather, captains should also weigh anchor, so that a ship can float over unstable waters, he added.

"The general standard of care in this situation is to monitor the weather, exercise caution, have a night watch, have the engine going, ready to maneuver," he said.

Wealthy clients push for impractical designs, expert says

Costantino said the ship's design and construction was error-free. But one yacht design expert disagrees.

"There's so many other factors, and this huge, complex boat is part of it," said Tad Roberts, a British Columbia-based yacht designer who has worked in the industry for nearly 40 years.

The Bayesian's giant mast is part of a trend of bigger and bigger yachts, according to Roberts. He worked on the design of the Asolare, formerly the Scheherazade – at 154 feet long, the largest cold-molded sailing yacht in the world when it was released in 2003, according to its manufacturer, Hodgdon Yacht Services. "It's small today," Roberts added.

Roberts said problems emerge when yacht designers can't say no to wealthy clients' demands for more and more extravagant and overgrown designs.

"The clients are wealthy people. They are very used to getting whatever it is they want," he said.

But owners' requests can compromise security, he said.

"Owners are not naval architects," he said. "They don't understand the issues involved, and trying to explain to them may or may not work, but there are compromises being made all the time."

Yacht buyers are more likely to get a better boat than they would 50 years ago, since yachts are exported and built towards international standards, he said. Still, the worsening effects of climate change and extreme weather are growing risks to anyone sailing the high seas, he added.

"Be aware. That's the biggest part of it," he said. "There's a possibility that things could go bad, that there is risk involved."

Yacht owners install million-dollar, AI-powered security systems

Piracy on yachts is even rarer than sudden storms – only two cases were reported between 2019 and 2023, according to the International Maritime Bureau's Piracy Reporting Centre . Still, superyacht owners are investing in James Bond-esque technology in an effort to protect their vessels.

"There's definitely increased concern," said Frederik Giepmans, managing director of safety and security at MARSS, a technology company that offers high-tech surveillance and security systems for superyachts with a price tag "from the hundreds of thousands into millions," he said.

NiDAR, a software program manufactured by MARSS to provide protection for superyachts, can pick up on objects approaching a yacht from the air or water "while underway, at anchor and in port," according to the company's website.

The surveillance system uses artificial intelligence and machine learning to handle data from sensors monitoring all sides of a vessel. The AI system provides "constant, long range monitoring of the air, of the surface, of the underwater, to try and give the crew as much response time as possible," said Giepmans.

That way, yacht owners can pick up on any manner of approaching objects, from "small, fast craft approaching on the surface" to divers and submarines under the water.

But if a threat is detected, a yacht owner's "options to respond are limited," Giepmans said. "You can get out of the way. You can bring people to safety. But, for instance, a more military response is not available to you."

Giepmans pointed to a recent increase in attacks on commercial ships, like attacks carried out by Houthi rebels on ships cruising through the Red Sea. "There's a gap there in terms of security," he said. "Because there isn't really, right now, a way for commercial or private clients, to respond, perhaps, in an appropriate way to these threats."

Luxury yacht owners cruising off the coast of Monaco, for instance, shouldn't be as concerned about a direct threat to their security, as compared with boats sailing through other locations, he said. "It really depends on that, as to what extent they will go to protect their ship."

The greater danger could come from adverse weather events, as the planet warms every year.

Meteorologists have pointed to a water spout, a tornado that spun up over the water amid the storm that hit the Bayesian, as a possible factor in its wreck.

Water temperatures in the area were more than three degrees higher than average that day, the perfect conditions for the spout to form and the likely result of climate change, Rick Shema, a certified consulting meteorologist and former member of the Navy, previously told USA TODAY.

"The water spout was an uncommon occurrence. But again, these things happen, especially in warmer water," he said.

Search Resumes for British Mogul and 5 Others After Yacht Sinks Off Sicily

The body of the vessel’s cook was recovered while divers searched the hull of the Bayesian for passengers, including the tech entrepreneur Mike Lynch.

By Elisabetta Povoledo

Deep-sea divers with Italy’s firefighter corps resumed their search on Tuesday for six missing passengers — including a British software mogul and his daughter — of a yacht that sank off the coast of Sicily the previous day.

Twenty-two people were on board the 180-foot British-flagged sailing yacht, the Bayesian, which was anchored near the port of Porticello, when it was hit by what witnesses described as a waterspout, a small tornado on water, during a sudden and violent storm.

Fifteen people who managed to get to a raft were rescued by the captain of a nearby sailing cruise ship. The body of the yacht’s cook, identified by news outlets as Recaldo Thomas, a Canadian Antiguan, was recovered on Monday. But several people are still unaccounted for, according to Salvatore Cocina, an official with Sicily’s civil protection agency.

Those still missing are Mike Lynch, a British technology entrepreneur; his daughter Hannah; Jonathan Bloomer, chairman of Morgan Stanley International; his wife, Judy Bloomer; Christopher J. Morvillo, a lawyer at Clifford Chance; and his wife, Neda Morvillo.

Mr. Lynch was acquitted of fraud in a U.S. trial in June, ending a high-profile, decadelong legal battle against accusations that he had defrauded Hewlett-Packard when he sold his company, Autonomy, to Hewlett for $11 billion.

Mr. Lynch and the others went missing days after Mr. Lynch’s co-defendant at the fraud trial, Stephen Chamberlain, a former vice president of finance at Autonomy, was fatally struck by a car on Saturday while out for a run, his lawyer, Gary S. Lincenberg, said in a statement.

Prosecutors in the Italian city of Termini Imerese, east of where the yacht sank, are opening a formal investigation into the yacht’s sinking. Reached by telephone, the chief prosecutor declined to comment.

The search for the missing passengers began on Monday but was suspended late that night as crews found themselves limited to the bridge deck and items like furnishings “obstructing passage,” the firefighters’ corps wrote on social media .

When divers resumed the search on Tuesday, ships trawled the waters near the site, the corps said in a statement. The Italian Coast Guard also said in a statement that search operations were “continuing unabated,” with the deployment of helicopters. There was no evidence that gasoline was leaking from the yacht, the Coast Guard said.

The yacht was lying on its right side in about 165 feet of water, meaning that divers, working in pairs, could stay underwater for only about 12 minutes at a time, said Luca Cari, a spokesman for the firefighters’ corps.

Divers were seeking a safe point of access to the vessel’s cabins. “Obviously, everything fell and the space is very tight,” Mr. Cari said, adding that the divers were having to remove obstacles, like furnishings and electrical wiring, that were “completely blocking passages.”

The firefighters’ corps said in a statement that it was impossible to verify whether people were inside the hull.

Mr. Cari said that several divers had been part of the search-and-rescue operations when the Costa Concordia, a cruise liner, capsized off the Tuscan island of Giglio in 2012, killing 32 people. It is considered one of the worst maritime disasters in modern Italian history.

“It’s like the Costa Concordia, but much smaller,” Mr. Cari said in a telephone interview, comparing the search operations. “In the Costa Concordia, we came across many obstacles but we somehow were able to overcome them. Here, the obstacles block the passages and have to be removed.” He added, “This makes it more difficult.”

Crews were also trying to raise the yacht, which experts will examine to try to determine why it sank. Until then, experts can only hypothesize what happened.

Karsten Borner, the captain of a ship, the Sir Robert Baden Powell, which picked up the Bayesian’s 15 survivors, said in an interview that when the wind picked up around 4 a.m. Monday, the Bayesian was about 490 feet behind his vessel. Once the wind wound down, he said, he could not see the yacht anymore.

“My theory was that she was capsized first and then went down over the stern,” Mr. Borner said.

Dario Boote, a ship structures and naval architecture professor at the University of Genoa, said: “Now I imagine that a whole series of lawsuits will be triggered, obviously to ascertain whether there is any responsibility, as always happens very unpleasantly in these situations.” He said, however, that in this case, responsibility might be hard to determine. “Clearly, only once the wreck is raised will we know more,” he added.

Several fishermen told Italian news outlets that they had witnessed a waterspout. Peter Inness, a meteorologist at the University of Reading, said they were relatively common in the Mediterranean, though their occurrence and intensity are unpredictable.

“Until one actually forms, you can’t start telling people where it is,” Mr. Inness said, or “how to get out of the way.”

The inclement weather — with lightning intermittently streaking through the sky — made it hard to know exactly why the yacht sank. Col. Attilio Di Diodato, director of the Italian Air Force’s Center for Aerospace Meteorology and Climatology, said the agency had registered intense lightning activity and strong gusts of wind in the area at the time the boat sank.

The Bayesian had one of the tallest aluminum masts in the world, according to its builder, Perini Navi. “Having a tall aluminum mast would not make it the safest port to be in case of a storm,” said Andrea Ratti, associate professor of nautical design and architecture technology the Politecnico di Milano. The type of intensity unleashed by a violent lightning storm “could have created a significant shock wave,” he added.

He, too, cautioned that “a lot of questions will remain until we have other elements at our disposal.”

Modern yachts are built to withstand meteorological events of reasonable intensity, and all international naval registers suggest that new ships be designed for higher waves and more frequent and extreme weather events.

But “this seems a case of an unreasonable extreme event,” said Emilio Fortunato Campana, an expert in Naval Hydrodynamics at Italy’s National Research Council. “In that case, no ship is 100 percent safe,” he added. “I think the Titanic showed that nothing is unsinkable.”
