    I'm kind of new here, but is it just like an aluminum boat? how heavy is the boat? I always think of what size would work and the go up a size, just because then you know it's strong! It can always be too weak but can never be too strong

        A few simple calcs should tell you the answer.
        Figure out what your loads are going to be, multiply by 1.5 for a safety factor and use simple Trig to determine tensile loads placed on the structure. If you need hep there on many books on this subject, and that will give you a better answer then just guessing.
        Also what material are you talking about? Stainless or regular Red Metal?
        In either case, do your homework

          Have you decided on the type of wheels/ hubs/ axles you'll be using for this?
