I agree, this boat needs a lot of work. Take a small plastic faced hammer or the butt of a screw driver handle and tap around the suspect areas, you'll be able to hear whether it's solid or not. I would have a mechanic check out the motor,you need a compression check,etc. I'd like to see why the hatch was caulked, that's just a storage compartment.That plywood patch on your fuel fill and vent channel, shows that a hack worked on the boat, lacking patience. But all in all, I'd say this is typical condition for a boat of this vintage.
