This is my first sailboat. The day after I brought it home and moored it on the lake, a neighbor (who is a good friend) complained about the Halyard making noise all night as it slapped around inside the mast (the Jib Sheet does the same thing), although my other neighbor said he loves the sound. So, other than tightening these sheets as much as possible, is there a way to reduce the sound as the boat rocks back and forth?
