Best Hull type?
Well, my uninformed (but gradually improving) ideas on this have me using dynel and resin over wood.
The interior space between the inner and outer hulls is to be filled with foam of some sort. I''m painfully aware of the potential problems with sealed space and moisture retention. I intend to take some time considering this problem. Perhaps removable access panels? I dunno...
As to lack of concern for the boats sailing characteristics... it isn''t so much a lack of concern as:
a) don''t care a whole lot how fast it goes
b) want it to be stable and forgiving
c) want it to be easy to sail single-handed
d) want it to be a comfy ride.
I want to sight see... not race. For me, I see it as more of a water-born RV.
