cable
hello joerg, if the keel has simply come unbolted, and the cable is still attached to the back of the keel, it is attached by a 1/4th inch eye bolt and you may break it off trying to lift the keel, so if you are under the keel, under water, trying to lift the front pivot back into contact so you can re-bolt the hangers, and the eyebolt snaps this keel may drop on you and pin you to the bottom. the cable is about ten to 15 feet long and you may have enough to lift it enough to get a sling under it while you are on the air filled dock. if the water is 10 ft. deep the keel, when attached, is seven ft. off the seabed, it weighs 600 pounds, how are you going to hold it over your head to bolt it in? have you been under to check, are the bolts broken off, is the pin shorn off, have the attach points been torn away, is the keel actually there?johnjohn
