Alternative to marvelous Buccaneer 24

I was looking over my three devils photos this morning. Are you going with a single beam and two masts still?

Never had two masts on 3 Devils, Nelson - but did on the sketches of the light, 10 metre cruiser. Sid is single beam while Devils is two - and the light cruiser is also single.

 

Nothing to do with B24 alternative but out sailing yesterday on the much altered Shifty, saw this interesting 4.8 metre Bernd Kohler bi-rigged catamaran - out for its first sail on the upper Waitemata.

 

Sorry about that Gary. I have three devils and the 10m light cruiser mixed together in the same folder. Love the shape of three devils.

Re Duo480 (Kohler)

Hi Gary
thanks for the photos, hopefully I can get to sail the thing in some real wind soon. BTW I tried sending you separate email but I dont know if it worked.

Sorry guys, dont want to hijack this topic either. If any members are interested in my boat I'll start a separate thread
cheers

i'm interested in seeing some more pics. Interesting looking beast. There is a recently launched Kohler 650(?) moored next to my boat now. Quite a distinctive look.

 

Looking at the Duo 480's Bi-plane rig brings to mind the canted A-frame, Bi-plane rig on the design board for the new RAVE V foiling trimaran.

This new A-frame has a mast-leg stepped on each ama and joined at the top in an arc.

How does this set up effect a trimaran's performance and stability ?
Has it been tried before ?

 

G'Day Brian,

Your boat looks really cool. It looked way bigger on the trailer.

I too must apoloigise for the thread hijack, but I'm giving serious consideration to one of Richard Woods' trimarans and I'm wondering about putting a biplane rig in each of the floats. Simply because of the weight of lifting a mast (old age). Would it work or are the loads/bury in floats etc a no go?

Hi Basil

thanks for comments.
As regards your tri, Im afraid you would have to ask someone on this site who might actually know something about the subject, like GB, DL and heaps of others

cheers

Theres non of us getting any younger.
Use a shorter foil shaped rotating alloy mast, with a low aspect ratio fully battened Fat head sail. Easy to use and much more efficient.

 

When i first launched the Cox's Bay Skimmer, it had two freestanding wing masts 6.5 metres tall ... and it was a struggle, on my own, to lift each one high and slide them into their deep sockets, if there was any breeze. Later, after I bent the forward mast lower section, I changed to 3 point stayed setups, cut the cantilever sections off and shifted the bearings on top of the deck. Much easier to step.

 

Thanks oldsailor,

I've given it a bit more thought and your suggestion sounds like good sense to me. I'll contact Richard Woods and get some plans. Now I just have to organise plans for a (plywood?) wingmast. Anybody got any ideas?

Gary you were a brave ******* lifting a 6.5 metre plus wingmast and getting it to drop into a tight fitting hole. Kudos to you.

Bas.

 

Wellingtonian Paul Jackman came up to Auckland to see the old gang and to look at the Volvo fleet in port; here two old farts, Matt Urquhart and some other bloke with wet and dry paper, spin old stories and complete BS beside Sid - before the Cox's Bay tide comes in to float the little rocket. That's the Cox's Bay Skimmer in the background.

 

Sid

Cool! Did you always have a daggerboard in Sid? Great,awesome, looking boat...

 

No. Earlier I had much deeper, lifting J foils - but the windward performance was not good enough, also the windward foil often water dragged - so I built the high aspect ratio dagger and case (which when fitted blocked off the below decks forward section ... so no chance of a bunk there now) - and reduced the depth of the J's, removed the cases and fixed the foils solid with epoxy in the floats.
The setup now is very good for windward sailing, the foils lift just the same as before and the windward foil never drags.
