Hello,I have found a leak entering at Keel. The water appears about an inch up on the keel “ridge” Only when crew is in the boat. When boat has no crew members in it, this must be floating above the waterline. I cannot see any “hole” in the fiberglass coating. There appears to be a lump under the fiberglass coating here that looks like a factory fastener. Is that a throughbolt holding the two halves of the keel together?My question is how I might plan to effect a proper repair?This is for good boat number 3430.
