Personally, I would pass on that one. It shouldn't be like that. Maybe a bad grounding, maybe someone not knowing what they're doing when re-torquing bolts...whatever. John Cherubini II (the designer's son and a boat builder himself) said somewhere on this forum that, after an 'incident' with a Hunter 25 keel in San Francisco, Hunter went overboard on the hull-to-keel joint, using epoxy, something like 5200 around the bolts, etc. etc. JC II was of the opinion that the keel almost didn't need the bolts!
