Its a bit disappointing how little detailed information is available.. so I hope that others who want to try homebuilding will have a path to follow.. albeit strewn with the debris of my failures and misteps.
How about giving some of the builders/designers around a call, or take measurements directly off a boat if you need that kind of information.
Could you restate what you need to know? I'll fill in what I know or can find out. We want to keep you going on that project.
