Cabin leaks and wet core
Leaks and wet cores are probaly the most common problem on boats of our vintage, and not only Hunters, just take a look at the web sites for owners of other brands. Posts have the same theme, only the names are changed. When you consider that most fittings were just wood screwed into the plywood core and that the caulking or bedding material is close to or over 20 years old then leaks are bound to happen. By the time the leaks are noticed on the inside the core is already wet, and as a past owner of several wooden boats the quickest way I know of to get wood to rot is to encase it in fiberglass and keep it wet. Are the handrails loose? When was the last time the deck mounted blocks by the mast were checked? Is the caulking around the ports dried out from UV? A good place for leaks to start on the 37C is the staysail track, and not just the track but also the wood trim under the track. Hatch screws loose? Even the teak trim strip over the ports can let the water in, a drop at a time maybe but it adds up. The best fix is to pull everything off, check for wet core around the screw holes, dry it out, epoxy the core edges and remount the hardware with a good bedding compound. It is a big job but do it and enjoy a dry boat, or just chase down leaks for as long as you own her.
