I sail an Endeavour 32 and I am looking for some ideas to help prevent halyard slap. All of the halyards are external to the mast. The cleats and winches are covered up by the sail cover. I've tried loosening everything up and using bungies, looping the halyards around the spreaders, and nothing sems to work real great. Right now the mast looks like a cat's craddle, and it takes a half an hour to set it up. Is there anything short of running my halyards inside the mast that will help quiet them?
