My 88 searay floor has some soft spots right up the middle, and the ski hatch is bout to fall in. Can i just cut the floor out in the center of the boat and replace that since that seems to be the only bad part, or do i have to replace the whole floor, and i did pull the carpet back to see things a little better, and how do i know where to cut the floor, i mean how close to the hull, and how do i find the screws that r holding the floor down since the floor is glassed over, if it going to b just as much work just to rplace the center as the whole floor, myswell do it all. And, just to let you know, this is my first boat, and i dont know very much bout them at all, thanks for the replies, and happy boating.
