I have a 15' Fiberglass drift boat. The fiberglass through out the boat is approx 1/8" thick. The bottom (floor) of the boat had small 2"x3"X1/8" squares between to layers of fiberglass, the bottom and floor of the boat. The top layer (Floor) began cracking and i started seeing moisture coming up through the cracks. When i started investigating i realized that these small squares were all soaked and rotted, no longer sticking to the haul of the boat. So I have removed the floor layer of fiberglass and the wood squares beneath it. My question is, what should i replace it with? I am thinking of epoxying 1/8" layer sheets of a hard wood, while staggering the joints ending up with a 1" wood floor that is epoxied together and to the fiberglass bottom and then cover it completely with fiberglass cloth and resin. I think that this will improve the strength of the boat while keeping the performance. Attached picture shows gutted boat and exposed fiberglass bottom. Any info is much appreciated.
