I just bought a project boat and have been looking trough this site for answers and can't find anyone with quite the same problem. I haven't ripped the carpet up yet to see, but i have two small...maybe 6 to 10" soft spots right infront of the bench seat. Can i repair just these bad areas or do I need to replace the whole floor? How do i start...just start cut out a square of rotten wood? Everywhere else seems good and solid.
