I know I've seen a discussion about this before, but can't for the life of me find it.
I have a '22 swing keel that will spend the summer on a mooring. After bring it out to the ball this weekend, I drove by the marina a couple of days later to check on it and noticed that it was trying to sail while on the ball -- swinging from side to side, etc. much more than a lot of the other boats out there, though it was fairly breezy. The mooring field is pretty protected (very small bay) so there wasn't anything to speak of for current or wave action.
I have a standard hank-on jib (not attached) and the main is in a sail-bag on the boom. Nothing else on deck, etc. to catch the wind. I'm attached to the mooring ball (the anchor chain, not the ball itself) with a y-yolk with one leg going to each bow cleat. I also have a safety line attached to the d-ring on top of the ball going to the trailer winch eye with enough slack in it that it doesn't have any tension. Rudder is in the water, and lashed so that it stays centered and the keel is fully down.
I was thinking the yolk might be a little too short -- I'm pretty close to the ball, but when we attached we adjusted the scope to be about the same as the other boats in the field. Other than letting out some line, I'm not sure how to calm down the swinging.
