Re: water were it should not be
You have a salvagable boat there, though I wouldn't be caught dead in it because that hull will beat you to death. No offense!
This project could be pretty easy if you can get the cap off. remove the console, remove the rubrail. Under the rubrail will probably be pop rivets holding the top cap and the bottom hull together. Chances are, this is also where over the years water was getting into the hull. The boat could be foam filled completly and probably is. The foam could be completely soaked and will never dry out completely. The foam can make it very hard to get the cap off.
If you can't get the cap off, the other option is to cut the floor about 2 inches in all the way around and remove it. Either way, once removed you will be able to remove all foam and see how much the water has rotted the stringers out if they are wood. If your stringers and transom are in good shape, it is just a matter of refoaming, putting the deck in and sealing up anything that may leak water into the bilge.
Obviously alot of work, but on this size boat can be done reasonably cheap and is nothing you can't handle with the help from the experts around this sight. Good luck
