The problem with a composite boat is the composite material is covered with a fragile gelcoat. The composite material is insanely tough to folding, direct impacts and such abuses but not grinding. What the waters in Nova Scotia do is grind your boat on the abrasive granite. Since we bought this boat in October it has been abused. The 8 day trip in the tobeatic really put a strain on her. Her gelcoat was ground down in some spots right to the composite material. Also some of the single gouges were deep enough to penetrate to the composite. Once this is exposed it needs to be patched. The last thing I want is for the fibres to be torn on the granite. Today we started our first patch of her, with many more to come. We are learning how to do it. Hopefully in the summer we can do a much better job and make her shine again.
