Last Saturday I was on a friend's 1984 C22 when his shackle holding up the main let loose. We returned to dock and retrieved the upper end of the halyard after lowering his mast, and replaced the defective shackle. To unstep his mast, we had to hold up the upper end of the mast since we didn't have a crutch for the stern with us and the slot in the step was not sufficiently high to allow the mast to sit on the stern railing, adding to the difficulty.Question: If we had had a sandy beach (which we didn't this time), might we have been able to reach the shackle if we placed the boat broadside to the beach, raised the swing keel, then pulled on the jib halyard to heel the boat over enough to reach the upper end of the mast with the hook on our whisker pole?
