Re: Fiberglass Layers
That depends on how thick the wood will be. In my opinion, you could do what you propose, but it is not necessary. It will make it stronger, but that is not where you want your strength. It will also add a lot of expense and weight. If you replace the stringers, that is where muliple layers are a good thing. When I did mine I used mulitple layers at the joints and seams, with a single layer to sheath in the floor. Stringers got two layers with a third at the joints. Transom was plywood layers with a layer of mat between. It is more than strong enough. Also, if you put floatation foam under the floor, it adds a lot of strenght and stiffness, so you don't need the floor itself to be as thick. Good luck...
