    If we estimate the gross tonnage of a 45' keeled sailboat and use 12' beam and 6' depth, we get

    .375 x 45 x 12 x 6 /100 = 1.215 (?)

    Plug it into oced.

    Cgt = 49 x 1.215^.67 = 55.8

    56 x 70-90 man hours per say 80 is 4,480 hours for amateur go it alone.

    Perhaps CDBarry can give us the interpretation and hours estimate for the boat in question as I am guessing.

    I never understand these dreamers in the first place. Its common knowledge if you spend one week driving round every boatyard and marina on a stretch of coast you'll find a distressed yacht at a bargain price to refit way cheaper, quicker and less risky than designing, building and equipping a home made boat. I really don't get it..

    Yes, but for sure less cooties than the boat design and building process the OP talked about in post #1 & #3 . . :eek:

    — better the devil you know than the devil you don't — used to say that it is better to deal with a difficult person or situation one knows than with a new person or situation that could be worse —

    Note ‘‘could’’ is ‘‘will’’ in this case from all the OP's posts so far . . ;)

    You can build a thousand square foot house with 20 or 30 facets on the outside. You can also build a thousand square foot house with 5 facets. Likewise, it mostly depends on how you think you're going to fit the boat out.

    Not at all. A structurally sound boat is based on good design and construction techniques. The fit out is not as relevant as long as it doesn't overload the boat.
