I am working on a small open bow boat. It has less than 50 square foot of floor to replace. I have a layman's understanding of why a cored floor is better, stronger and lighter. I have a couple of fitment issues if the floor is too thick. My question is regarding layers thickness and strength of a solid fiberglass floor. My widest span is about 2 feet between stringers. Can I get enough strength from about 1/4 inch or possibly up to 3/8 of an inch of solid glass alone? I have already built a mold to make this floor in one piece, but I decided I could use some advise first.
