Locked or unlocked?
Bret, I have just bought a C22 as well. In the stock arrangement, the locking bolt just pushes against the side of the keel when tight. I don't think that it does much to stop the keel from moving. As a matter of fact, if you forget the bolt and winch up the keel it won't stop you. It will only dig into the side of the keel. I think that what it may be good for is if you are in heavy winds and waves, it prevents the keel from swinging when the boat is heeled over too far. If you loosen it up so that the bolt pulls out all the way, I believe that the hole will leak water into the boat. So be careful. In mine I can see the bolt when I stick my head in the settee access hole so I can see if there's any water comming in. I would ease it out until it's almost completely out for starters. The only thing that you can check on the keel if it's in the water is the side play which indicates if the hole for the main hinge pin has too much play. If you rock the boat you can hear a clunk as the keel hits underneath. There are some things about the keel you can't see even if it's on a trailer. If you are unsure about the condition of the keel assembly, I would haul out, drop the keel and check it over completely. From what I figure, you really don't want to loose the keel or have it swing down from the up position. These two failures are catastrophic to the boat. If it is an older boat, the main hinge pin and hole through the keel could be worn. The 4 relatively small bolts holding the keel should be replaced. If the pin or the bolts fail in the water, the keel will sink to the bottom. You really want the cable and winch working properly. If the keel is up all the way and the cable fails, the keel will swing down and damage the hull. There is a brass turning ball with a slot for the cable inside of the volcano / rubber hose that can get stuck and abrade the cable. If the rubber hose decides to leak, the boat will sink at anchor since the volcano is below the water line.At any rate, on my 1987, I have to assume that there has been no maintenance since it was bought and am going to play it safe. I'm going to replace the 4 keel hanger bolts, the main pivot pin, the turning ball, the cable, the fitting on the keel for fastening the cable, the rubber hose and it's two clamps and refinish the keel. At least....These things need to be done here while the boat is propped up on supports because the trailer won't let me lower the keel for removal. Since I will have access to the hull, I will also paint the hull with ablative paint. I have already had to tighten the winch bolts and many other fastenings around the boat as well.~Bilbo
