All, I have a 1981 M-15 that I bought last summer. I was working on preping the hull for some paint when I noticed something curious about the center board trunk and keel. It appears to me that the bottom of the keel (fiberglass) has separated from the center board trunk liner. There is about a quarter inch gap running on each side of where the glass at the bottom of the keel appears like it should meet the center board trunk liner. The gap is not there at the back or front, but curiously it does not appear to me like the bottom of the keel fiberglass is displaced a quarter inch like I might have expected if the glass let loose. I do not store the boat in the water so I do not know if this is letting water in or not. I have not noticed a problem when sailing. Can those familiar with the keel/centerboard liner joint help me understand what should be there and if this is broken as I assume offer some advice on repairing it? Thanks Robbin M-15 in VA
