Buccaneer 24 Trimaran

[bruceb]

I am experimenting- but I am also trying to address most of the issues. I am using the stock trunk, but only part of it, the rear will have a filler block and the front is open so I can tilt the board aft. My board is only 325mm cord and starts to taper about half way down so I can raise it part way with out creating turbulence. The area I sail in has lots of light air and a little extra area is usually justified for the frequent tacks. I have printed templets for a NACA 6308.5 and a 64a8.5 as a start. I am certainly open to others. I will probably use the 63 series for a little more stall resistance. I consider the board sort of a "tuning" device that I can change. Anyway, I may hit something and Have to replace it - our lake is still 20' low. Bruce

There must be lots of viewers of this thread who only have a vague idea of what a Buc. 24 looks like. So:- Heres a three-view.
Note the near round bilge and outriggers which barely touch the water.
This is what makes this little boat so fast in light airs.

Thanks, I don't have that sheet in my plan set. I never had seen the stock rig plan. Bruce

Gorgeous models old pilot/sailor - IMO trimarans and aircraft are evolving into somethng very similar - and with your modelling skills would suggest you design and build an enlarged ultra-lightweight aircraft model/trimaran, say 7-8 metres long??

Buc 24 # 151- The deck was removed before I bought the boat. It makes a really roomy daysailor Bruce

Thanks

Also, this may be of some interest

this is the list of 21 measured multihulls that have raced and fit the 8.5 rule in NZ from fastest to slowest using a mathematical formula.

Creepy Crawler is a Hughs 25.

YEA GBE's RULE.

Are the GBE cats in that class production boats or customs? We only see a very few of the larger ones here in the US.

The GBE is an out and out racing machine.

Comparing the 28' Cat with a 24" Tri is like comparing chalk with cheese.

Is the Buc24 originally designed as a racer or as a cruiser or both? Thanks

Theres no need for any mods unless you are going to engage in serious racing. It is plenty fast as it is.

It was designed as a simple "Pocket Cruiser". Only use the provided alternate spade rudder if you feel you don't need the convenience of a "Pivot up" type rudder.

Regarding the daggerboard, you only need to make it with the exposed part having its leading and trailing edges parallel and the tip squared off in line with the box bottom. The little bit of extra area is beneficial and with the board up, the box mouth is closed.

The stock rig and sails as shown are fine and should not be altered unless serious racing is anticipated. You don't want to frighten your family. LOL.

Hope this helps.

My boat sails quite well with one reef in the main, which is pretty close to the stock sail area. I would want a light overlapping jib for light conditions. I use a self-tacking jib for day sailing, it allows the boat to be managed with one hand in most conditions. Bruce

Over here there are a mixture of production (glass) and amateur built GBE's - usually from DD ply 2 layers of 4mm if my memory serves me. A bunch of them have been exported over the years. A couple of years ago Malcolm Tennant told me he still occasionally sold a set of plans.

The GBE's racing in the 8.5 class all have bigger rigs and some have hull mods to get more bouyancy forward and a full length waterline, so aren't really 'stock' GBE's anymore. Sam's Capricorn has smoked most of them at one time or another.
