ABSTRACT:
A tubular float for use in a water ski tow device. The float has a hollow shaft pulley in one end thereof and a slot in the other end thereof. A hitch rope is attached to the transom of the boat at locations displaced from the central axis of the boat. The hitch rope is roved through the pulley. A tow rope is inserted through the slot and passed along the tubular body of the float through the hollow shaft of the pulley back along the hollow body of the float through the slot from an opposite direction and then tied or spliced to the main length of the tow rope to form a tow structure not susceptible to failure in the event of structural damage to the float.
