I just boat an old boat. (1973 cotton cordell goin jesse) I would like to use it to fish for just a few years until I can buy a newer one. The floor is soft in the front going under the deck. i don't mind trying to repair the floor but i don't know how to get under the casting deck. It seems to be a one piece molded fiberglass. I don't know how to remove the casting deck without taking the whole top of the boat off. anybody have any suggestions?
