Buccaneer 24 Builders Forum

I had a daggerboard in my Bucc 24. It and the case were strong and I never had a problem with it. However the threat was always there

I had a pivoting CB in my Bucc 28. It was Magic.

On the formula 40 trimaran I'm building Kurt Hughes has a sacrificial tip on the daggerboard as well as crushable foam insert if the worst comes to the worst mind you the board is over 11 feet long so serious loads there.

G'day 'Corley' I'm a retired (Ha) ex-yacht builder/repaired. Live inland from Cairns in FNQ. Sure am interested in the 'KH' 40' tri you're building. Tell us a bit about it. Please. I'm sure many others would be interested if they knew how good a 'KH' design really was. Sure hope to hear from you. Have a great festive season & Ciao for now, james

My initial intention was to buy Kurt's boat and ship it out from Seattle but other expenses hit me at the time and I could not make it happen. So I've purchased a plan set instead. I've not built a boat using the cylinder mold technique before so it will be an interesting project. I'm currently having the cylinder mold sections cut by a nearby CNC shop and should have them early in the new year.

The boat is demountable and can be packed into a 40' container for transport and designed to the limits of the Formula 40 rule it's 39'3" beam gives massive righting moment and in the vicinity of 1780kg in weight it has a 20m mast and a sailplan with genoa, blade and masthead assymetrical spinnaker, my plan is to keep the fitout really basic and spend the money on the best sails and equipment. It's designed for singlehanding or doublehanding I have a few ocean races I hope to compete in when the boat is complete.

I was such a lucky young man in the 70's that I worked with the Glennie brothers for Lock on the 55ft tri "Spirit of America". At Lock's request, I built a test model of his "C" class cat, intending to build and race the real thing. A woman got in the way and I ended up in Europe, largely on dry land.
Now that I'm semi retired and moving to Port Stevens I intend to build a 25ft cat or tri. Wish me luck. Rob L.

I've always been curious about "Spirit of America" and never been able to find out much about it, was it a Kraken 55 like Yumi Maru/Power Brewing?

[old dog]

Hi Corley. Yes it was a Kraken 55, built for "Mad Mike Cain" as he was known, for single handed racing. It was so fast that it was scary. In truth I think it was a bit overpowered. Since sailing on it I've never been so excitedly terrified on anything since.
Thankyou Loch.

I have found the B24 materials list on the site ( the one with the plan and profile plus the material list with a couple of sheets of construction directions) and am wondering if its fairly accurate for the wood sizes required? I am going to start milling some Sitka Spruce while I wait for plans and would like to ensure I have sufficient supplies on hand (and of the correct dimensions)
Thanks

MM, I think the plans are accurate for the spruce required, but since our local ply is only available in 4x8' , you will have to buy more than is called for in the plans. Also, the larger cabin shown in the revised plans uses several more sheets. It is still about the least material for any thing close to its size, performance and ease of construction. Good luck.
I haven't built one, but I have had my buc for 4 years and have done quite a few repairs so I have some feel for new construction. The plans are easy to work from, but some understanding of sail boats and wood construction really helps. Also, there is some translation necessary from Australian to American terminology, and maybe Canadian B

[oldsailor7]

Bruce.
AFAIK 4'x8' is the standard size for all plywood in the UK. Canada and Australia----same as in the USA. ?

[mugsman]

Thanks for the information regarding plywood requirements. One other question regarding the posted cut list - are the timber dimensions close to the full list that comes with the plans? I plan to add an additional 4 to 5 ft. to the length on the stringers to ensure I have sufficient material to extend the stern as suggested.
Thanks

[cavalier mk2]

4'x 8' in the states Paddy, longer lengths can sometimes be ordered.

[bruceb]

Just plan on more ply than is called for, and I would mill about a 1/3 more stringer stock than is called for and use the very best pieces.
IMO, the boat would sail better and carry a load much better with about 2' more aft- BUT!!!, adding it makes it a whole new design, and probably will require lofting and some design changes, and will add 1/3 to the construction time and quite a bit more ply. Go very carefully! The Buc, as designed, is a very light ply box structure engineered around the length of 3 sheets of ply, and almost every panel is load bearing. Even parts like the cockpit coamings contribute to the torsional stiffness. If you change anything, you are now building a prototype and doing your own engineering- certainly ok, but you are on your own. B
