I have a '86 Catalina 36 Tall Rig. Bought it last year, sailed it for a season, then put it up on the hard for the winter. She came with a trailer and she spent the winter on it.
When I went to get her ready to launch this year I noticed some of the fairing around where I presume the keel stub joint to be was blistered, so I scraped it away to get a better look and found a crack. Having read about Catalina smile I went looking around the boat further and found a cracked aft stringer (the one under the fuel tank), and what look like stress lines in the bilge and what looks like a crack around a keel bolt.
Does the heel joint crack usually run parallel to the ground? Or am I looking at something worse, such as a cracked keel stub? Or is it far down enough to be the actual keel? I haven't attacked it with the grinder yet.
