I'm looking at buying another boat. Its an 18' deep v aluminum hull. The owner says the floor is starting to rot and is soft in some spots. I havent been able to go and see it My question is what is the floor attached to on an aluminum boat? are there wood stringers like in a fibersglass boat or is there an aluminum frame under the floor or am i completely wrong on both accounts LOL. Ive put floors in fiberglass boats but never tore apart and aluminum hull boat. I'm trying to put together a ruff estimate as to what this is going to cost and time wise. Thanks for your help guys
