Late last year I purchased a 1983 Catalina 22. With the warmer weather I've been in the water to look at the keel. It's heavily rusted, the surface is very rough and small pieces of rust (1/8") come off in my hand. The previous owner had the boat for 6 years and had never raised the keel. My question is - can the keel be too thick with rust to raise and/or fit into it's slot? Or worse yet could it wedge into the slot and get stuck? I'm ordering Catalina Direct's DVD to help with removing the keel and repairing it. Thanks.
