Attached is a photo of the barberhauler on the front beam I got from Performance Cats 2 yrs ago. Its not the best picture since the boat is stored for winter and cover was on. The white line with blue marks is the barberhauler. Knotted end would attach to block around jib lines. Line exiting cleat to center side of boat leads to other side barberhauler.
The white line with red with the small cleat below barberhauler cleat is for mast rotation control.
