I just rescued a 1978 J24 from the crusher. It has many deep hull blisters below the waterline, the floor core is rotted out, and the keel fiberglass has de-laminated. She may have frozen with water in the bilge. It has one main, jib, and spinnaker sail, and a single axle trailer. Otherwise it looks to be complete. Should I try to restore her or should I part her out?
