We recently bought a 1982 37C. During survey soft area was found on the deck, aft and starboard of mast. Down below water was noted dripping down mast (not too much water). Previous owner noted the leak and installed a mast boot in attempt to resolve the leak. Why the mast boot on a keel stepped mast? It has not rained in this area for a few weeks, so where was water coming from? Initial plan is to cut into the deck in the noted soft area and inspect it. Also will remove mast boot and collar in attempt to locate source of water. The water may have been squeezed out during repeated stepping on the soft area during the survey. Any ideas or experience with this problem and how to fix it?
