any one have a columbia 24 or have had one? my wife and I are going to look at a 1980 columbia 24 tomorrow and would like a little insight on any problem areas or concerns. I did some research on google but I cant find too much information about the boats. I found the columbia community web site but I found it difficult to navigate to find any suggestions on concerns or things to look out for. one thing I found interesting is the ad for the boat mentions a inboard gas engine but everything I read online says they only had a outboard mount. any help would be greatly appreciated.  

I think there is something amiss here. Columbia made three 24' models in the 1960s, but none in the 1980s. See here.

here is the information I found, but its pretty vague Challenger 7.4 - Used Sailboat Market in Canada  

I have a columbia 24..1964 ..not a challenger though..very sturdy..no issues yet..third owner.depends on what your looking for.I sailed on tanzers at first. the columbia has ample room, easy to sail..slow but steady. have done most of my restoring myself..pain to get replacement parts and a not very friendly user columbia site.  

FWIW: Still sailing my 1963 Columbia 24 - she turns 55 this year!  

Still sailing my 1964 Challenger; she takes on a bit of water when sailed hard but I have a good bilge pump.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

The COLUMBIA 24, COLUMBIA CONTENDER 24, and COLUMBIA CHALLENGER 24, all have hulls that are the same or similar, and derive from the earlier ISLANDER 24.

I am picking up a 64 Columbia 24 tomorrow. Typical "Grandpa died 15 years ago and we don't sail, so we let his boat go to shit." story. Anyone sailed one? Seems to be a stout little boat. I got it free and only really took it for the roller furling and sail collection. I may keep it around for my next project though.  

Pretty good for a 64 year old small boat. They did build them better back then, didn't know how thin a layup they could get away with so they're built heavier than modern boats. I'm actually looking at one in our mooring field right now. Probably better maintained than yours but it's a pretty little boat. I'm a Columbia fan, I'm on my third now, a 1969 Columbia 36.

It's a great boat! Built stout, sails well too. If you need the basics to get it sailing, I'm happy to help. 877-932-7245 x116

Columbia made a couple of variations in 64 for the boat. Found this bit of history that might interest you. Columbia Sailboat Model Specifications Looks like it would be a great little boat to coastal cruise. Information is the 24 was used to circumnavigate the world.  

I have a good friend who sailed all over the pacific in a Columbia 24...when he was much younger. He survived a rollover in a typhoon and did not lose his mast. I owned a 1977 Columbia 8.7 and later a 1978 Columbia 10.7. Having grown up in California for my 12th birthday I had a tour of the Columbia plant in Costa Mesa. Yes, I think they are great boats.

Thanks so much! This boat unexpectedly fell into our hands. My girlfriends brother had it, but with a new wife and brand new baby, he wasn't able to give her the care and attention she needs. He was going to scrap her, but he gave her to us instead. We haven't been able to do a lot, but we've cleaned her up a bit, and started oiling and varnishing the wood. We haven't raised the sails yet, but we've motored out into the L.A. Harbor channel, that was exciting!  

Sean Lowe said: We have a 1963 Columbia C-24 that we're starting to work on. Everyone I've talked to says they're well built, sturdy boats. We also have thousands of questions about this boat and sailboats in general. This is our 1st boat, and we no nothing about sailing!

Well done Sean. It is a start. Next step. While motoring raise the jib in a mild breeze. Idle the motor and let the sail become the power. Baby steps. Make a Friend in the marina and invite to take you sailing on your boat. Show you the ropes.

2 years late! I own one of these and it’s great! Super sturdy, sailed it in Gulf of Mexico, Atlantic coast, and pacific. For the size nothing beats it’s sturdiness. Fast too! We won a regatta in it a few years back. Doesn’t hold as good a close haul as fin keeled boats, but handles chop and roll quite well. Can hold a 7.5” dinghy on the foredeck too. Does average about 3 it’s in light wind, 6.3 in good winds.

The Green Blue Announces Launch of 2024-25 University Sailing Sustainability Challenge with new sponsorship by Royal Thames Yacht Club

19 th September 2024 – The Green Blue is thrilled to announce the launch of the 2024-25 University Sailing Sustainability Challenge (USSC) , beginning on 1 st September 2024 and running until February 2025.

Since its inception in 2015, the USSC has encouraged University Sailing Clubs (USCs) across the UK to adopt more sustainable practices, and this year marks a significant milestone. The challenge welcomes the Royal Thames Yacht Club as its new sponsor, bringing fresh energy and support to the challenge.

In addition to this new partnership, the 2024-25 Challenge introduces a revamped judging criterion, allowing clubs to be even more creative and flexible in their approach to sustainability.

Supported by the British Universities Sailing Association (BUSA), the USSC was created to help University Sailing Clubs (USCs) across the UK become more sustainable. Clubs participate in the challenge by appointing a Sustainability Officer who in turn will commit to The Green Blue Boating Pledge . They then select areas of focus from eight categories, including reducing waste, protecting biodiversity, and combating climate change.

Over the course of the challenge, clubs, and their Sustainability Officers complete tasks within their four chosen categories with the aim of submitting evidence of their work to the USSC judging panel.

An exciting opportunity for clubs and students to really show what they can do; the panel awards all clubs who participate and complete their tasks with an official USSC certificate of achievement. The judging panel also score all submissions with the top four participants being selected to receive a prize at the USSC Awards Ceremony, held during the prestigious RYA Dinghy & Watersports Show in February 2025.

“The younger generation of sailors are the future of the sport and it’s amazing how many of them are passionate about sustainability. By getting involved in the USSC, it’s a great way for individuals and university clubs to not only earn recognition but also set an example for the wider boating community. The work they do can make a real difference in protecting the environment, both in the present and for years to come.” said Kate Fortnam, Campaign Manager at The Green Blue.  

Last year an impressive 14 universities successfully completed the Challenge, showcasing their dedication to fostering sustainable values within their clubs. This year, with the support of the Royal Thames Yacht Club, The Green Blue anticipate even greater participation and impact.

“At the Royal Thames Yacht Club, we are committed to the adoption of sustainable practices both within the Club and on the water, and as such are delighted to be supporting the excellent University Sailing Sustainability Challenge. Our young people are the future, and it is critical that future is sustainable. May we thank all participants in this most worthy of causes.” said Richard Powell, Vice Commodore at the Royal Thames Yacht Club.

“We, the university community, benefit hugely from being a part of then the green blue challenge. Through the challenge we push ourselves, our clubs, and the clubs we sail at, to be more sustainable and to look at the ways in which the sailing community can support the protection of our waterways and our planet” said Amelie Sadler, Vice Chair at BUSA – British Universities Sailing Association.
