Does any one have a fix for a 1970's rudder popping out of its brass fitting in a good wind? I have tightened the wing nut until the brass plate is bowed but still having problems. I don't have a carriage bolt sleeve anymore on the carriage bolt would that matter? Do they still sell these covers for our old sunfish 1970's models? Any help would be great as the young sailors are discouraged from using the older boats because of this.
