Re: Catalina 22 Swing Keel wobble

Dean,
By the way. The keel MUST fit loose on the pin, and in the trunk! The keel has to move side to side slightly as it is a quite irregular piece of iron that does not match the inside of the keel trunk closely. When heeled sailing everything is quiet. On a mooring the keel is a pendulum and swings and bangs. If you want to stop that just put a lot of your stuff on one side when you leave so the boat heels on the mooring, and the banging will stop completely.

If someone were to repair your keel and make it a nice close fit on the pin THEN you would be in danger of loosing it! That is because a sloppy fit means that the four bolts holding the pin blocks into the hull are only carrying the weight of the keel, and even less when heeled over. If the pin fits tight then the keel is a huge lever trying to pull the bolts on one side out of the hull when you are heeled. It very well may succeed. That is why my repair method using hte PVC pipe to form the hole actually needs to make the oversize hole.
