This is some of the decking that was torn out. It appears it was replaced already once before the previous owner got his paws on it. I found old gobs of sealant and old unmatched paint everywhere. The previous owner must have decided to replace it again from the rear seat up with this. The factory decking bonds to the hull is about 8 inches from the gunwales. This unpainted 3/4 inch plywood was installed butting up to the gunwales so it was higher than what it need to be. Wood shims (scraps) were installed on top of the stringers to raise the support, and 2X4s were placed directly on top of the fuel tank to support the middle. I did not get any photos of this, and I kick myself. It was all screwed together and screwed to the stringers. Not only is this stupid, it is not safe. Since the sides of the deck were not bonded to the hull on the sides, the boat would not support the forces imposed while underway. The deck is designed to distribute the loads along with the stringers. It appears this was all fresh work. Who knows how long the boat was used with this setup. At least there is no stress cracks in the hull, so all is good.
