Has anyone ever rigged or purchased anything that will silence the whistling that a mast makes? I keep my '75 Mariner in a slip adjacent to my condo complex and it's keeping my neighbors up at night. I was thinking of trying to raise a line rigged with one slug inside the mast hoping that would "fill in" the crack and divert the air thereby quieting the whistling but I don't know it that would work. Any ideas anybody? Any help would be appreceiated!
