ABSTRACT:
A tandem towing device for towing a pair of water skiers with one boat has a hook for attachment to a boat, a plate rotatably mounted on the shaft of the attachment hook, and a pair of diametrically opposed holes in the plate for attachment to two towlines. The holes receive the towlines through corresponding channels disposed about the perimeter of the plate. The towlines are retained in the holes in the circular plate by sleeves which slide about the towlines and into the holes. When the towlines are put in tension by normal use, the plate rotates to eliminate any tangling of the lines which may exist.
