I am currently in the process of restoring a 15 'x 4' fiberglass boat. When I bought it the floor and stringers were rotten and had to be removed. I would like your opinion on what fiberglassing materials any of you would recommend. My plans are to use 3/4" plywood to lay my stringer down the center. I will also use it in the two shorter ribs on the sides of the center. My plan is to use a 6 oz woven cloth with the US Composite 635 thin epoxy with medium hardener to glass in the stringers and to use on the floor. I was thinking a 1/2 sheet of plywood for the floor. I am new to the fiberglassing world. I am wondering if I am going a little overkill on this size of a boat? Would 4 oz be better? I would also like any recommendations on what type of plywood I should use. Do I really need marine grade for this small of a project?
