I recently bought a 1987 30 ft Catalina. I paid for a survey to be conducted however due to a lack of professional due diligence he didn't catch the fact that the area in and around the mast is sunken and compressed into the deck. Has anyone out there had a similar issue with the mast and how did you fix it? I'm guessing that I'll have to remove the mast tear into the deck and remove whatever material is found underneath. After removal I'll have to re-fiberglass and/or epoxy the area until it's level once again.
