Re: need help with this wellcraft
Not to discourage you, but take a stroll through the retoration forum. Chances are very good that soft spots in the floor mean rot in the stringers and or transom. Rot usually starts at the bottom (as that's where the water sits) and works it's way up to the floor.
All's not lost, my guess is you picked it up for a project, not a turnkey ready fishing vessel. When restored, it looks like it will make an excellent platform to fish, cruise, or lounge about on.
