OK. I’m looking at a 1995 C30 MkIII and I can see a few concerns. First, the boat is on the hard, there is a crack in the fiberglass headliner/door frame just forward of the mast. The way the crack is it prevents the door to the head from closing. I think this is being caused by hogging/sagging of the hull as it is sitting on the hard. The deck at around the mast feels sold. Is this something I should be concerned with before making an offer. The second concern is there are blisters on the wings of the keel. I know the keel is iron, so oxidation/rust on the keel beneath the paint can cause the blisters. Again, concern? How would these issues be currected?
