I just posted info about repairing the hull-deck joint, here... http://www.laserforum.org/showthread.php?t=34166 I kept going on the repair of this '79 hull so this thread is about fixing the cockpit drain hole and the hull separating from the deck at the rear of the cockpit. Background: I bought a spare boat against all the advice I give to people. It was heavy, it had been in a barn, it had water in it, the guy was really nice, and someone else was "headed up to look at it tomorrow." Gawd, good thing I don't go to used car lots. I needed it to lend to a clinic instructor that weekend, so I bit. This boat, I believe now, was sailed without a drain plug many times. There was an old soggy cork inside the hull. It was stored deck down and froze, probably several times. When I cut portholes, the deck sandwich was soaked. The deck rail had separated and crumbled in several places (covered up with mud in his yard). The first time we sailed it, we drained it and still had trouble lifting it onto a car. The cockpit drain hole in the hull and cockpit had separated, someone tried to seal it with goop, and when the hull flexed the hole was slightly broken out. So, I cut two portholes on the aft deck and one next to the centerboard trunk where my good boat has one. The drill squished through the foam. I put a small fan on one hole and let it run for a week or more. It's dry, with a bit of must and mold to be cleaned up.
