Hello, I have a Hunter 49, wing keel and have noticed water in the sump under the generator. The boat has not been hard aground. I hauled the boat to put a new bottom on her and noticed two hairline fractures about 8" long on the leading edge and the same on the trailing edge at the butt joint of the keel and keel stub. Does anyone have any thoughts about whether or not the keel bolts should be retighted before doing an epoxy repair at the crack? Thanks.
