Mark,
Was that 1 or 5 questions? smile

This is a chined version of the second generation hull shape.

It is considerabley more bouyant than the earlier Blade shape particularly forward of the front beam.
The relatively flat bottoms of the hull are now converted to chines.
This should deliver even more dynamic lift off the breese. The additional fore/aft stability will allow the crew to trim upwind for min drag and the sharper bows will slice very efficiently through the chop. There is no steaming required to achieve this shape and very little fairing so building can be from either ply or foam glass sandwich. The insides construction has been significantly simplified. It is no harder than building a pair of kayaks. I found it all just good fun. But I like this type of stuff.
Regards,
Phill

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
