Old glass boats with rotten wood buried in several layers of plywood with water logged foam are all too common. About half of the guys I know keep their boat outside year round, uncovered. Many have patches on top of patches and motors that barely run but they keep going.
All are broke old guys who retired years ago and most won't spend a nickle to do it right if cheap suffices for now.
When I lived in FL I had a neighbor there who owned a 1950's era half wood, half fiberglass 14ft boat. He would run out of Gov. cut in Miami every weekend, he'd go out late on Friday, and stay on the water till he caught fish, sometimes staying out in that tiny boat for three days sleeping under the bow deck adrift in the ocean. A few times he drifted too far, one time he drifted into a storm and nearly sunk the boat. He did it till he was in his early 80's. He gave the boat away after he fell overboard trying to rinse his hands of cut bait and almost didn't get back in the boat. The boat had a mid 50's Johnson 15hp on it that was missing its cover for years. He'd also take a bottle of Jim Beam with him as well, he said it helped him sleep and not worry about the boat sinking while he slept out there.
He would go out there, with no radio, no phone, no tools, and no registration on the boat, He said he had paid enough for the boat back when it was new and he's not paying any more for it. As far as I know he never got stopped or asked for papers and never got any tickets.
