BMW ORACLE Racing Designs World’s Biggest Wing with Computational Field Dynamics

By Larry Boulden | March 11, 2010

This February, in the picturesque Spanish port of Valencia, BMW ORACLE Racing’s skipper Russell Coutts will take the helm of one of the most technologically advanced – and hopefully fastest – boats ever built, in a bid to capture the 33rd America’s Cup. The most remarkable feature of the trimaran – named “USA” – is that it will be powered by an enormous wing, rather than a conventional sail.

As Mike Drummond, BMW Oracle’s Racing Design Director explains: “A wing of this scale has never been built for a boat. In terms of size, it dwarfs those on modern aircraft. Towering nearly 190 ft (57 m) above the deck, it is 80% bigger than a wing on a 747 airplane.” It was analyzed using a process very similar to CFD, using CD-Adapco’s Star-CCM analysis tools.

In an interview conducted by CD-adapco, Oracle’s CFD Manager Mario Caponnetto explains how STAR-CCM+ was used to optimize the aerodynamic design of the wing, at the expense of traditional wind tunnel testing.

Why this choice of a rigid wing on your trimaran, instead of a conventional sail?

[MC] Rigid wings are not really radically new in yacht racing. They have been used in high performance catamaran races and other racing boats for many years. By the way, a rigid wing first appeared in America’s Cup in 1987. What is radically new is its size: the wing, with its 57 meters above deck, is the largest wing ever, 80% larger than a 747 aircraft wing. No one in our team had designed anything like this before, and this scared us a little bit at the beginning. Starting from white paper and evaluating pros and cons, we decided to move forward and quickly in the project. This project came true thanks to the enthusiasm of our chief designer, Mike Drummond.

What are the benefits and the shortcomings (if any) of a rigid wing?

[MC] The main advantage of a rigid wing is shape control. In other words, depending on the angle and the velocity of the wind, there is an optimal sail geometry that in turn optimizes the aerodynamic pressure field. This makes it possible to extract a maximum propelling power from the wind – to maximize efficiency. On a conventional sail, material works, from the structural point of view, like a membrane and shape control is difficult. Some specific shapes are impossible to obtain and the final shape is a compromise. With rigid sails, shape is much easier to control without compromises. Furthermore, during navigation there is always a feedback between imposed shape and achieved shape, whereas with traditional sails it is already an issue to identify the sail shape during navigation.

What are the aerodynamic benefits of the rigid wing?

[MC] One of the main benefits is shape control, aiming to control lift forces and to reduce drag forces. To do so, the wing is made of a front rotating element and eight independently rotating flaps. This makes is possible to change the vertical aerodynamic load. Between every flap and the frontal element lies a slot that favors air flow between the two sides of the wing. This makes it possible to delay the stall and to dramatically increase the maximum lift. In practice, the wing is able-even with light wind-to lift the central hull of the trimaran out of the water and reduce its resistance, even though the wing lateral surface is less than half of a conventional sail. The wing horizontal sections are more aerodynamically shaped than a thin sail. A sail profile is efficient at a certain angle of attack, more or less when the flow is tangential to the frontal edge of the sail. At smaller or larger angles, a flow tends to separate from the sail, thus reducing its efficiency. The rigid wing, with its rounded front edge, is much more tolerant to variations in the angle of attack. Even at a small angle of attack, the wing will still create lift and push the boat, whereas the sail will beat like a flag and restrain the boat. This is a noticeable advantage during maneuvering, in particular when tacking, and is one of benefits that are most valued by our team’s sailors.

Could you share more details on the aerodynamics simulation aspects?

[MC] STAR-CCM+ is a finite-volume approach to CFD. (It allowed us to) exploit the “client-server” architecture of the CD-adapco software. We could use a remote supercomputing cluster facility located in Italy. While sitting in our offices in Valencia or San Diego, we could check in real time the progress of the simulations running on the cluster. This happened thanks to a lightweight client-or if you like the final user-based on a Java interface, and a C++ server-or if you like the supercomputing cluster.

Second, of course, usage of the supercomputing cluster leveraged the STAR-CCM+ capability to scale well, i.e., to exploit the capability to divide the processing tasks between several processors in parallel. This was necessary since computational meshes for aerodynamics can reach several million elements.

The third success factor was process automation. STAR-CCM+ includes a CFD simulation engine (the solver) but also all the preprocessing phase (including construction of the computational mesh) and post-processing. This means we could build one complete workflow, or pipeline, and implement it over and over again during our optimization studies.

So, CFD is a tool for the happy few?

[MC] Situations like America’s Cup (AC) or Formula 1 require a tremendous accuracy and detail since the engineering situation is pushed to the limit, and the optimization requirements for factors like aerodynamic drag can be orders of magnitude more sensitive than in mass production boats or cars. I think that AC will continue to be one of the best benchmarks for CFD tools that can, in industrial situations, be applied in standard design offices based on small clusters or even PCs. Nowadays, all CFD processes should be automated in industrial situations, whereas AC pushes the application of the code to its limits in terms of physics, computational mesh or hardware resources. This creates a feedback process between the STAR-CCM+ developer, CD-adapco, and CFD teams in America’s Cup or Formula 1, and the feedback has a (benefit) on other sectors.

Munich/ Valencia. The BMW ORACLE Racing team has won the 33rd America’s Cup, dethroning Swiss holder Alinghi. The challenger’s spectacular trimaran “USA 17”, with its futuristic 68-metre wing sail, defeated the catamaran “Alinghi 5” in the waters off Valencia on the second day to record the decisive second win. The best-of-three match ended 2-0 in favour of the US crew of owner Larry Ellison. This Deed of Gift series saw the holder and challenger go head-to-head in a straight duel.

“Congratulations to Larry Ellison and his whole crew!” said Ian Robertson, BMW AG Board Member for Sales and Marketing. “The goal we have all been working towards for over two and a half years has now been achieved. This has been a fantastic performance by the whole team. As Technology Partner, we have also made a successful contribution to winning the world’s most prestigious sporting trophy. We have positioned BMW as a competent partner in competitive sailing and have firmly established the transfer of technology in the America’s Cup. On the construction side, BMW engineers have set new benchmarks for intelligent lightweight design. Added to which, among the relevant target group, BMW is the highest-profile brand in competitive sailing.”

With 159 years of history, the America’s Cup is the world’s oldest sporting competition and brings together the best professional sailors, yacht designers and boat builders of their generation in the pursuit of perfection. For the 33rd America’s Cup, the BMW ORACLE Racing designers and engineers were charged with one of the most exacting challenges in the long history of the event. The design rules were wide open, and experts from a wide variety of specialist areas, such as materials research, aerospace, composite materials, electronics, data analysis and numerous branches of engineering, have all played their part in the design and construction of the high-tech yacht.

BMW engineers, for example, contributed their knowledge and EfficientDynamics expertise in the area of intelligent lightweight design. The aim was to build a yacht that was as light and torsionally stiff as possible and could stand up to the rigours of the race. In multihull racing, it is particularly important to keep weight low, as the yacht which can raise a float out of the water the quickest has a major advantage. The transfer of knowledge from the BMW engineers was not a one-way street; the valuable expertise gained over the course of the project will all find its way back to the BMW Research and Innovation Centre (FIZ). BMW has been involved in the America’s Cup as a Technology Partner since 2002.

The future involvement of BMW in the America’s Cup will depend on the development and organisation of the competition going forward. As Robertson explains: “We will make a decision on our further involvement in the America’s Cup over the coming weeks. What is already certain is that BMW will continue to be represented actively in yacht racing. We will go on playing an active role in raising global interest in sailing in the future and continue to use projects such as the BMW Sailing Cup and regional events in the various markets as a platform for customer relations and to further strengthen the BMW brand values.”

The BMW Oracle Racing 90 trimaran is a lot of yacht

The BMW Oracle Racing 90 trimaran -- one of the largest, and possibly fastest, ever built -- hits the waters of Rosario Strait for initial sea trials. However, an ongoing court battle will determine if the boat is eligible to race in America's Cup.

Share story

ANACORTES — It’s not that easy to make the jaws of old salts drop around Puget Sound, where shipyards have been cranking out boats of every conceivable size and shape for more than a century. But a carbon-fiber behemoth stalking the waters of Rosario Strait this week is getting the job done.

One look at this trimaran — one of the largest, and possibly fastest, ever built — as she lifts her sails and leaps into the breeze off Orcas Island leaves no doubt: This boat wasn’t built to spend a lifetime plodding through seawater.

She was meant to fly.

Not literally, in a Spruce Goose sort of way. Although in early testing, even in light winds, the behemoth BMW Oracle Racing yacht — which, depending on a court decision, may or may not compete for the America’s Cup in 2010 — has lifted her side floats almost as far out of the water as Howard Hughes’ famous seaplane ever rose.

• Feds OK key stretch of Eastrail in Snohomish County

This is all by design, on a boat that can squeeze 40 knots out of 20 knots of wind and might yet become the fastest racing yacht ever known.

Even to the untrained eye, the boat, officially known as BMW Oracle Racing 90, is an engineering marvel, one that went from blueprints to sails-up in less than nine months.

Her sleek, carbon-fiber main hull is 100 feet long, stem to stern, and 90 feet at the waterline. Her twin floats are 90 feet apart, side to side. If you dropped the boat through the open roof of Safeco Field, it would cover the entire infield.

When the boat is pushed from its dock by four bumper boats, it appears as if a piece of the shore has just calved off.

The boat’s three hulls are connected by sweeping, aerodynamic carbon-fiber beams that look perilously thin. They have a unique droop to them, making the craft, from the front or rear, look a bit like a Klingon Bird of Prey spaceship from an old Star Trek movie.

The carbon-fiber mast, the only crucial part not fabricated on site in Anacortes (it was built in Rhode Island) is more than 5 feet wide at its elliptical base, and 158 feet tall.

The sails are similarly off the charts: a 5,000-square-foot mainsail; a 3,500-square-foot headsail; and 7,000-square-foot gennaker.

The boat will be sailed by about 15 sailors, wearing protective helmets and high-tech garb that looks like it’s borrowed from NASA.

Those are about the only hard facts revealed by BMW Oracle Racing, which will complete initial sea trials here Saturday, then prep the big boat for shipping on a barge to San Diego a week later. There, testing will be ramped up, as syndicate officials await the decision in a court case which might render the boat essentially useless, in America’s Cup terms.

A bitter fight

The pursuit of sporting’s oldest international prize has devolved into a bitter legal fight between two billionaires: Oracle software icon Larry Ellison of the Bay Area and Ernesto Bertarelli, a biotech mogul who runs the Swiss racing syndicate, Alinghi, which currently holds the Cup.

Since successfully defending the Cup in Valencia, Spain, last year (Ellison’s team again did not make the finals), Alinghi, to put it simply, has been unable to reach agreement with all competing syndicates on a fair format for the next Cup races.

Ellison’s BMW Oracle group last year won a court decision that named it the “challenger of record” for the next Cup, meaning they would negotiate the next Cup’s protocol with Alinghi. When Ellison and Bertarelli could not agree, both sides began preparing for the next remedy under Cup rules: a match race between their respective boats with essentially no design rules, other than a 90-foot maximum waterline.

That is the lesson lingering from a 1988 America’s Cup challenge, in which Dennis Conner’s Stars & Stripes won a legal decision allowing it to race a multihull against a slower, plodding New Zealand challenger in a San Diego race now considered a low point in Cup history. Since then, it has been taken as a given that any Cup challenge without protocols agreed to by the defender and challenger of record would be conducted in multihulls.

That’s what sent BMW Oracle’s design team into trimaran warp speed on Puget Sound, where the team had built four previous conventional carbon-fiber monohulls with Janicki Industries in Sedro-Woolley, and where other useful composite-construction infrastructure exists because of the local aerospace industry.

But last month, Alinghi won an appeal of that court decision, and announced plans to stage a traditional Cup defense, in monohull boats with multiple challengers, in Valencia as soon as 2009. Ellison’s group is making a final appeal of that appeal, with a decision expected in February or March.

$10 million bet

If Ellison wins, the big trimaran could race for the America’s Cup in what by all accounts would be a spectacular best-of-three multihull match race with Alinghi in 2010.

If it loses?

The designers likely scurry to build a new monohull. And the trimaran becomes a big, fast, very cool, black-and-white elephant, with design and construction costs estimated to be as high as $10 million.

This boat is, in other words, not only a hedge on a bet, but something of a guilty pleasure, and the BMW Oracle sailing team, based for now in Anacortes, is treating it as such. Not even the world’s greatest sailing racers have ever seen anything like it.

“We’re not even at 50 percent yet and it’s already pretty impressive,” said helmsman James Spithill of Australia, the former driver of the Seattle-based OneWorld Challenge Cup team in 2002.

Spithill and famed helmsman Russell Coutts of New Zealand both were hired by Ellison after his most recent, unsuccessful Cup effort, and both are now in Anacortes.

Initial driving duties, however, have fallen largely to Frenchman Franck Cammas, hired as a consultant because of his expertise with mega multihulls, which heretofore have been built primarily for open-ocean racing, and reach speeds up to 44 knots.

The new boat has been sailed only in light to moderate winds, progressively increasing loads on its joints and surfaces. But even at about half speed, the boat is a marvel in the water, its speed deceptive because of its massive size.

When its center hull clears the water and the craft seemingly takes flight, riding on only the knife edge of a single float at about 20 knots, it’s a spectacular sight.

Needless to say, the boat, visible from miles away and accompanied by a half-dozen chase boats, creates a spectacle in the otherwise quiet waters in the waning days of summer around the San Juans. Seagulls steer cautiously wide of it. Snoozing salmon trollers are startled to attention and sent reaching for cameras.

And despite the thrill it gives the sailing team, there’s still a bit of tension in the air whenever the big boat lifts off the water. For each voyage, the boat’s tenders carry — in addition to telemetry equipment monitoring onboard sensors — a physician and scuba divers in case of emergencies.

Design coordinator Mike Drummond, mindful of the high-stakes poker game with Alinghi, skillfully dodged most questions about the big boat’s particulars this week. But asked what keeps him awake at night during testing, he didn’t hesitate.

“Pretty much everything.”

USA17 (BMW Oracle Racing 90)

In 2007 Russell Coutts approached VPLP to design USA 17 , the fastest racing sailing boat to contest the America’s Cup . Little did the team know that the project would take three years of relentless modifications, improvements and developments to produce a trimaran featuring 35 m floats and a 68 m pivoting wing mast! Proof of the pudding came in 2010 with victory over the Swiss catamaran Alinghi in both races of the 33rd America’s Cup in Valencia (Spain).

For VPLP, it was the most enriching and intense investment of time and energy that the firm had ever known. Winning the America’s Cup justified VPLP’s approach of continuously researching and testing hypotheses. It also vindicated the firm’s policy of optimizing weight, power and simple yet efficient sail plans, a policy applied to each and every boat designed by VPLP.

Syndicate relaunches trimaran

• Associated Press

SAN DIEGO -- From San Diego Bay to Lake Geneva, it's going to be a busy week for the bitter rivals set to sail for the America's Cup in February.

The challenger, BMW Oracle Racing of San Francisco, relaunched its massive trimaran on Monday after the carbon-fiber boat was significantly modified during the last four months.

The space age-looking craft, which is 90 feet long and wide, was moved by crane from a temporary boatshed to its berth on San Diego Bay. It will be refitted with its mast before being load-tested to make sure it's seaworthy. Sailing on the Pacific Ocean is scheduled to resume later this week.

"This is cutting-edge technology and sailing. We look forward to testing how fast is fast," helmsman James Spithill said in a statement.

BMW Oracle Racing is scheduled to face two-time defending America's Cup champion Alinghi of Switzerland in a best-of-three series starting Feb. 8 for the oldest trophy in international sports.

Whether this boat, known as BOR 90, is the boat that will face Alinghi remains to be seen. BMW Oracle Racing, owned by software tycoon and sailor Larry Ellison, has refused to confirm or deny reports it is building a second boat. Ellison is believed to have spent between $10 million and $20 million on the boat that was relaunched Monday.

If BMW Oracle Racing is building a new trimaran, the current one would at least serve as a sparring partner.

Early Wednesday morning, with the Alps as a backdrop, a giant helicopter is scheduled to lift Alinghi's equally exotic-looking catamaran from a boatyard in Villeneuve and launch it on Lake Geneva. The Swiss cat, which has been described as resembling a praying mantis, is 90 feet on the waterline and reportedly has a bowsprit that makes it 120 feet overall. It's believed to be not quite 90 feet wide.

The rare one-on-one showdown is the result of a convoluted two-year court fight in which the American syndicate's backing yacht club was declared the rightful Challenger of Record.

Alinghi gets to pick the venue. A decision is due by Aug. 8, six months before the first race. The Swiss are reportedly considering Abu Dhabi, United Arab Emirates, apparently feeling their catamaran would excel there in light wind and flat water.

With the size and speed of the giant multihulls, it could be the most spectacular racing in the 158-year history of the America's Cup.

BMW Oracle Racing's trimaran is capable of sailing two to 2½ times the speed of the wind. Its mast is as high as a 16-story building and the mainsail is twice the size of a Boeing 747's wing. The boat's three hulls would cover the diamond on a major league baseball field and are just shorter than an NBA court.

Boats that size can be lethal, too. BMW Oracle Racing's sailors have been cautious while sailing their big boat, including wearing crash helmets and life vests, hardly the normal America's Cup attire.

BMW's sailors are en route to San Diego to resume testing the trimaran. The outer hulls, or floats, appear to have been significantly reshaped.

"We are really excited to get out on the water," Spithill said. "We still have plenty to do to complete sea trials and be ready for the America's Cup in February so every day counts. It is only seven months until the America's Cup so we are now in the home stretch."

The trimaran was launched late last summer in Anacortes, Wash., and underwent initial sea trials on Puget Sound. It was barged to San Diego and underwent two testing sessions on the Pacific Ocean.

SAN DIEGO—After more than a year of practicing for the America's Cup, the U.S. team is replacing its boat's lofty 60-meter mast and 620-square-meter cloth mainsail with a hard, fixed wing that is 80 percent larger than a Boeing 747 wing and will tower 58 meters above their giant trimaran's deck. The team, known as the BMW ORACLE Racing Team, will start to practice with and evaluate the high-strength yet lightweight carbon-fiber wing on its 27-meter carbon-composite trimaran later this week.  The Americans have been testing new frontiers with the loads that their massive multihull endures while sailing . Crash helmets, personal floatation devices and other body armor have been de rigueur during BMW ORACLE Racing's practices—even while using a mast and a mainsail, which preceded the wing. During a practice session on November 3, the boat's huge mast snapped and toppled into the Pacific. Thankfully, no one was injured. Although the team's research and development unit has been conducting a forensic evaluation of the mast mishap, another unit has been finishing the assembly of the wing under the cover of a huge tent at the team's base in San Diego, in an attempt to keep the technology a secret from competitors. The America’s Cup is the oldest actively contested trophy in sport and dates back to a race held in 1851 in England in which the yacht America beat 15 boats representing the Royal Yacht Squadron.  Members of the winning America syndicate donated the Cup via a Deed of Gift to the New York Yacht Club on July 8, 1857, specifying that it be held in trust as a perpetual challenge trophy to promote friendly competition among nations. According to an Allianz Economic Report conducted in co-operation with Tom Cannon, dean of Buckingham University Business School, the America's Cup ranks just behind the Olympics and the FIFA World Cup in terms of worldwide direct and indirect economic benefits that accrue to the winner and the event's host city. It is the largest inter-club sporting event in the world in terms of economic scale and impact. The only other time that a multihull and a wing have been used in the America's Cup was in 1988. Back then, the U.S. team defied tradition when they unveiled an 18-meter catamaran equipped with a wing to compete against New Zealand's 27-meter monohull. Burt Rutan , whose company Scaled Composites went on to win the Ansari X PRIZE for SpaceShipOne , and who worked with John Ronz, David Hubbard and Duncan MacLane on the 1988 wing, reflected on that achievement: "The wing-sail designs were more challenging (than aircraft wing applications) because they needed high lift in both directions and because we had a requirement to vary the wing twist to account for different wind gradients above the sea. An aircraft wing lifts in only one direction and does not have any twist control. On the wing-sail we twisted the third element and thus had to make it torsionally flexible." The scale of the 21st-century sailboat and wing is astronomical compared with the 1988 vintage. The 1988 wing height was slightly over 30 meters, and its area was approximately 165 square meters. The new wing's main element is a monolithic box with an aerodynamic nose along its leading edge. Hinges at different points along the main element's trailing edge can be adjusted to change the gap between the forward and the aft elements to adjust airflow depending on the wind velocity. The sections of the trailing element can be moved independently to induce camber (the asymmetry between the top and bottom curves of an airfoil), making it possible to flatten and even induce negative camber in the top section as well as camber in the opposite direction in the lower sections. According to BMW ORACLE Racing, "the primary advantage of the wing over a soft sail is that it is easier to control and does not distort. This makes it easier for the trimmers on board to maintain an optimum aerofoil shape in a wide range of conditions." Unlike conventional monohull and multihull sailboats , the BMW ORACLE team's trimaran sails upwind and downwind at apparent wind angles less than 30 degrees (Monohulls typically sail at between 30 and 40 degrees upwind.) On board the racing machine it always feels as if the wind is in the sailors' faces. The wing technology will improve the trimaran's apparent wind angle, and may enable the multihull to exceed  two to 2.5 times wind speed. The upcoming America's Cup challenge will be the first time ever that an onboard engine will be used to assist trimmers in controlling the massive foils by powering hydraulic controls for the wing and the forward sails. Mark Ott, co-founder and executive vice president of Seattle-based Harbor Wing Technologies, the first company to employ a wing that rotates 360 degrees and uses a multihull as a platform, commented, "BMW ORACLE'S boat represents the pinnacle of race boat design; however, the nature of this design limits the wing sail's range of motion due to the shroud and forestay wires used to support it. This design limitation causes these wing sails to be impractical for use by the average sailor. By not allowing the wing full 360-degree rotational capability in everyday sailing conditions, it is bound to it be held on a shroud wire by the wind and damaged, or worse, possibly causing the boat to capsize." All eyes will be watching to see how BMW will store the boat and the wing, because the latter is not nearly as easy to take down and stow as a cloth mainsail. The America's Cup showdown is set to take place in February 2010 in Valencia, Spain.

The mast will be installed dockside and the boat will be load-tested before the huge multihull is tested by the crew in the waters off Point Loma. "We are really excited to get out on the water," said helmsman James Spithill (AUS). "We still have plenty to do to complete sea trials and be ready for the America’s Cup in February so every day counts. It is only seven months until the America’s Cup so we are now in the home stretch." BMW ORACLE Racing is the Challenger for the 33rd America’s Cup. The team will meet the Swiss Defender Alinghi in a best two-of-three head-to-head duel starting February 8. The venue for the competition will be named by the Defender by August 8. The team will test the trimaran in San Diego this summer. "This is cutting-edge technology and sailing. We look forward to testing how fast is fast," said Spithill.

French crew helpout with initial launching and first test sails Based in Anacortes on the west coast of the United States since 21st August 2008, the skipper of the Groupama Trimarans and his team are full of praise aboard the 90 foot trimaran BMW Oracle designed by the French architects VPLP. After the initial sail trials, Franck Cammas gives us his take on events. 'This trimaran is the only one of its kind. She is fairly extreme and has enormous potential. We're gradually taming her'. Designated as helmsman by Russell Coutts, the triple winner of the America's Cup, during these initial outings, the skipper of Groupama has been collaborating with the American Team as a coach and consultant for over a year. On the water, the power emitted by this trimaran which is over one and a half times the size of Groupama 2 is impressive. As wide as it is long at 27.5 metres, equipped with a mast which culminates at 50 metres high, a 500 m2 mainsail and a 700 m2 gennaker, she is designed to sail close to the shore in mild conditions. On deck, the twenty or so crew are kitted out with helmets. At the helm, Franck Cammas is discovering 'a very pleasant boat which slips along nicely. During our first beat the crew were very tense'. As the hours went by though, in a very light breeze, the cosmopolitan crew familarised themselves with the monster: 'There are three French sailors aboard including Bruno Laurent who, as is the case aboard Groupama 2, is the boat captain, and also Thierry Fouchier, the headsail trimmer, who has been sailing in our team since 1998'. 'Though some of the crew are only just discovering multihull sailing during these initial trials, it's a bit different for us. My discovery is centred more on being a team and learning another way of working. It's a very enriching experience' adds the skipper of the Groupama trimarans, who continues: 'This experience is very beneficial for our team as we're going to be able to transpose part of this knowledge onto Groupama 3, which is in the process of being reconstructed at the Multiplast yard in Vannes'. Another member of the Groupama team present in the United States for the past two months, Jean-Marc Normant has been following the end of the construction of the BMW Oracle trimaran: 'It has been manufactured to a remarkably high standard. There has been great attention to detail despite the very tight timing; the work taking just nine months.' The project is something that the head of Groupama's design office, Loïc Dorez, has had a great deal of involvement in, particularly during the design phase; thus enabling the BMW Oracle Team to save precious time. It now remains for the discovery to continue: 'We're going about it very progressively. Everyone is highly concentrated and rigorous as they're aware of the risks linked to the power of the boat and the sail surface.' With a surface area equivalent to that of two basketball courts, the black and white trimaran is continuing to fill the crew with wonder. All they have to do now is to get the very best out of their steed in view of the duels which may take place if the New York Court of Appeal decides the trimaran event will go ahead in 2009.

Cammas comments on sailing Oracle tri Franck Cammas commenting on the BMW ORACLE Racing 90-foot trimaran, "It is the first ever boat of this size designed and built for in-port racing and match racing only. She is very impressive, and the size of the mast is just amazing. We haven't gone full on yet. We need to build up our confidence and then we will be able to sail more aggressively. The boat is designed for light winds. She reaches the (103-foot) Groupama's top speeds easily, however much quicker than G3. Now it would be different with 25 knots of wind, and Groupama 3 would be quicker. But this boat is exceptional under 15 kts. We are still very careful. It's extreme, we must not take risks. There is a lot of pressure when bearing away, we could feel the pressure amongst the crewmembers when we did it for the first time." -- Full comments: http://tinyurl.com/SButt0914e Cammas has been working with the American team as a consultant. While competing for the Jules Verne Trophy to set a new non-stop around the world record, Cammas and his crew were rescued February 17, 2008 off New Zealand when Groupama 3 capsized following the breakage of her port float. http://www.cammas-groupama.com/en/index.jsp http://www.boatdesign.net/forums/showthread.php?t=21098 Another 'Round-the-World' Record Attempt, Groupama

BMW Oracle in San Diego We were on the water this past Sunday, as we sailed past Point Loma, we could see a large Tri South of us. There she was. They did not dust the sails to much, and seemed to have issued hoisting the main, unless they were just careful increasing the sail load. But that gave us an opportunity to watch her at close range and shoot close up pictures. She is an amazing boat and from what I read, we should be able to see her again since she is scheduled to do sea trials in San Diego for a couple of months here is a link to the pictures http://gadeyne-us.spaces.live.com and videos http://www.youtube.com/pgadeyne

Hello Cadiver. Thanks for the photos. #22 of the 39 sure caught my attention.

There is definitely a 'wow' factor to the giant trimaran BMW Oracle, which began sailing off San Diego this past week in anticipation of a possible court-ordered one-on-one America's Cup match with Alinghi. In fact, after viewing the boat and talking to helmsman James Spithill, it would be sad if the trimaran – which is 90 feet on the waterline with a 90-foot beam – never saw action in a race. 'While it is our desire to go back to a conventional America's Cup, it would be a huge shame to not see this boat in some type of competition ,' said Spithill on Saturday afternoon after returning from the boat's fourth – and most challenging – sail out of its temporary San Diego Harbor base. With seas running almost 10 feet with an opposing wind chop, the BMW Oracle crew got the conditions they had hoped for when they decided to come to San Diego. Only, it was sooner than expected. 'The perfect scenario would have been to go from one-meter to two-meter to three-meter seas,' Spithill said. 'We skipped one and two and went straight to three. 'We anticipated the sea conditions. What surprised us today was the wind (14-15 knots top). We got more wind than expected. The loads on the boat shot up a lot. We tried all the systems under dynamic loading. BOR90 sailing off San Diego - BMW Oracle Racing © Photo Gilles Martin-Raget Click Here to view large photo 'This was the first time the boat has really been tested. Even so, we were very cautious. The boat is designed to twist a lot. The loads on the boat are incredible.' So are the sounds. The slapping of an outrigger across a wave resonates through the carbon-fiber hull like a small explosion. 'There are a lot of loud noises on any carbon-fiber racing boat,' Spithill said. 'Because of the size, everything is magnified.' Ah, the size. The overall length of the boat is more than 100 feet, with the waterline length being 90 feet. The raked mast thrusts 158 feet into the sky – it can easily be seen above the Convention Center from its berth adjacent to Joe's Crab Shack on South Embarcadero Park – with the mainsail being twice the size of an International America's Cup Class monohull. ...courtesy SailWorld

Understatement.. "'We anticipated the sea conditions. What surprised us today was the wind (14-15 knots top). We got more wind than expected. The loads on the boat shot up a lot. We tried all the systems under dynamic loading." 14-15 knots in 3 metre seas. I wonder if they'll ever publish the numbers. Twisting moment alone has to be significant. I hope they do get to race it. That will be an event that I won't miss.

Sexy is an understandment! This is one sexy craft...it should be sailed by Stormtroopers only! Whew, can hardly contain myself. More pix please!~Caragirl

Kevin YF Moderator

In an interview with Valencia Sailing James Spithill (helm) mentions that in 18 knots of wind they've approached 40 knots of boat speed. That beast is going to be a benchmark the day she's raced in earnest! LINK to interview.

Each map type offers different information and each map style is designed for a different purpose. Read about the styles and map projection used in the above map (Satellite Map of Krasnoyarsk).

Satellite map

Satellite map shows the Earth's surface as it really looks like. The above map is based on satellite images taken on July 2004. This satellite map of Krasnoyarsk is meant for illustration purposes only. For more detailed maps based on newer satellite and aerial images switch to a detailed map view.

Hillshading is used to create a three-dimensional effect that provides a sense of land relief. Shadows drawn on a map simulate the effects of sunlight falling across the surface of the landscape.

Geographic map projection

A map projection is a way how to transform points on a Earth to points on a map. This map of Krasnoyarsk uses Plate Carree projection. The Plate Carree projection is a simple cylindrical projection originated in the ancient times. It has straight and equally spaced meridians and parallels that meet at right angles.

All projections from a sphere to a plane are distorted. The drawback of the Plate Carree projection is that it doesn't make an attempt to compensate for these distortions. For the general view of Krasnoyarsk, this is not a significant problem. The detailed maps use the Mercator projection which preserves the shape of small areas better.
