My "Gut Feel" (not a marine engineer
) is that a very small wood-composite catamaran
would have a poor bouyancy ratio.
How about a glass-over foam construction? This is how composite aircraft are built. The foam can either be left in, or scraped out to provide a hollow hull
. Foam is easy to shape. Proper molding foam is different from conventional packing foam, many of which will disolve in the fiber-gel.
You could get creative, perhaps, and use things like old milk jugs, an old inflatable
airmattress, etc as mold
supports, or create a light-weight framework and apply fiberglass
over that - I believe chickenwire is sometimes used for that purpose.
I'm about 95% certain that this will be a costly approach, though potentially rewarding to you. Complete hobie cats are widely available for < $1000, very often for $500 with heavy sun-rot.
