22 - 24 trimaran

[waynemarlow]

Looking at buildng a small trimaran in the 22- 24 ft range and slowly gathering contenders. Looked at the Farrier 22, Grainger ST7 and the Tritum 720 and others but no one boat seems to have all the attributes that really makes me want to own / build one. My question is are there any owners of the Tritum or Grainger who has completed there boats that I could talk to. Alternatively are there other boats out there that I haven't found. I think there was a French designer ( possibly Eric Larouge ) but I have't found any details. Any links would be helpful.

Thanks

What are the attributes you want?

AFAIA the prototype ST7 is in build and I don't know if anyones built a Tritium. Ask Paolo the designer. Kurt Hughes has 23,24 and 26'designs plus others. Eric lerouge has a 23 and a couple of versions of a 26'. Ray Kendrick has a couple of 22's and a 26. Grainger also has a nice 26'. newick has tremolino - square and round bilge. You might also like to check out the Marples CC26 - effectively similar in size to an F24. Don't forget Multimarine's L7 or the wonderfully named Exploder 25. Malcolm Tennant 26 Çoaster all have cabins. And there are daysailers like the CC23 and the new Multi 23 that look fun. get Suurfin'

Not having much luck contacting the designers, they must be on hols or busy. Anybody have a link to Eric larouge as googling him desn't come up with a link, his 23ft was a very pretty little boat with descent cabin. The ST7 looks pretty good just I would like a bigger cabin as the climes over here are not particularly hot. The Tritum is cool but doesn't have a folding mechanism ( marinas over here are bad enough to find for a mono let alone a tri )

Found the La Rouge design page, thanks

The ST7 started out with a cuddy a bit similar in size to the smaller of the F22cabin configurations. However as the design firmed up they did away with it. Shame really IMO it would have been a good alternative to the F22 R otherwise, even if it doesn't fold in the water. Needing a folder limits your options somewhat although the L7 seems to have a workable system of telescoping fibreglass I beams that is trailerable. Kurt Hughes offers a similar arrangement with alloy tubes for his 24, but I don't know how well it works.

I can supply Buccaneer 24 trimaran plans.
Arguably the best all round 24" trimaran ever designed.

Yes they are.

hi old sailor, What are you asking ?and is the aka design based on cold mold as one option to hard chine?
Thanks

Dear Old sailor , Could you send me a private message re. the plans I am not a junior by the way but wish i was.

No cold moulding. It is multi-chine construction with some subtle curvature in the panels. Much, much simpler to build , but still very efficient. Construction method does NOT need a strongback or moulds.
Plans include full size patterns, building instructions, bill of materials and extra drawings of alternative spade rudder and suggested inexpensive mainsheet traveller.
Also Trimaraner magazine article about the build, and a booklet on building with epoxy. US$150.00, postage and PayPal fee included.

m interested in building or modifying my amas. I think the new spinnaker and full batten main is more than crowther designed for. Anybody have any experience with new amas?

I don't think it is necessary to build NEW amas. But the bows can be extended to be in line with the mainhull stem.

Keeping the extended bows fair can be achieved by spacing the bulkheads further apart by 4" (100mm), forward of the fore crossbeam. Extra intercostal compression struts and an extra longeron stringer running to amidships, would provide the strength needed to resist the squeezing forces when driving hard with the extra power provided by a screacher or assymetric on a bowsprit.

There is a Green one racing very successfully in NZ with a huge increase in sail area.

JAMEZ has a very nice picture of that one, if he feels so kind as to show it.

There is also a very pretty Yellow one which has had the bows and sterns extended by simply sloping the stems more forward and the transoms more back. This has the effect of making the motion more "Silky" in choppy conditions, without adding too much wetted surface.

Here is a breathed on Buccaneer 24 named Miranda (formerly Gulf Chariot) - extended in stern to 28 and the too sharp stern sections rocker (what was Crowther thinking?) filled in and faired (which lets the hull "breath" properly, greatly reduced stern wave and no transom dragging), main hull daggerboard removed and new asymmetric foils (angled at approximately 25 degrees) in floats, new underhung and balanced rudder, rotating mast and 7/8ths rig. Boat is fast and much quicker than original - could be faster with taller rig.
