I spent the last 20 years spending 3 months a year living on a boat, I feel you - some of them are poorly done. I have seen many ship yards from the inside, from Sea Ray to Frers, and the higher end stuff is all done this way - but by high end we are talking $200,000+ for a dinghy and millions to make the mold for a full size boat. Bring that price down and cool things will happen. If you want to talk about it more email me at kevinsch@udel.edu, I'm very interested
