Well,

I think I've got it all done now. Last items seemed to have come down pretty quickly. Of course building the prototype is alot of work but the basic design is pretty much done. I even got some tricks that could allow making the hulls lighter, just in case. I also was pretty conservative with the weight calcs so you can drop some extra resin here and there.

I even got the costs sorted out to a large extend. If you really want to save cost then you have to build your own sail. Paying a sailmaker to do it for you at 610 Euro's is quite alot when the basic boat without a sail is only 2250 Euro's. And this last quote still includes the dotan rudders a 712 Euro's. If you are going to build this yourself then the ready to sail boat could be as inexpensive as around 1500 Euro's (1950 US$).

When you got more stuff laying around like blocks and shackles the price drop a little further.

I guess that soon the next stage will be to prototype the hull in cardboard at a 1:4 scale, trying to find the right panel layout and then prototype it in real life size.

I think the panels can be twisted quite alot, this should improve hull shape without having to go to compound curves or steaming the ply. It will allow a more pronounced V on the keel at the bow and have it run much flatter near the sterns. But also the sides can twisted a little bit to give hull a raked back bow and a modern wavepiercer bow section. And ofcourse the sterns can be twisted in a little bit as well if that improves looks. The deck is just curved in one plane, should be easier to close the hull off that way.

Yeah I think that with a trick here and there a pretty nice multichine hull can be made. Still I propose a square box shape like the arrows and arrafura's to test the rig and mast setup. These need to be prototyped first to see if the design works as intended. There will be no need to start right away on the more complex (and better looking) hull.

And then spend some time working out the right sail cut.
