The biggest problem is when sitting at the dock and the boat rocks back and forth the boom sways side to side, the boom opens and closes one cleat the opens the other, as the boom continues to sway the traveler car will move more and more until the slack in the continuous loop is exhausted. The only solution is to have extra cleats or tie the boom in a way that does not allow the boom to move. Now that you've added the additional tie down for the boom you have created tripping hazards.
