ABSTRACT:
A convertible water ski tow apparatus for a ski boat is disclosed. The apparatus includes a main tube and a bracket which are attachable to the conventional fixed ski tow pylon found in virtually all ski boats. The bracket affixes the main tube to the tow pylon and permits the main tube to positioned in either of two positions. In an upright position, the main tube acts as a vertical extension of the pylon, so as to facilitate and enhance wakejumping on conventional wakeboards, water skis, or other devices. In a horizontally extending position, the main tube extends outwardly from the boat, where it can be used for instructional skiing, barefoot skiing, and other applications. The apparatus is readily convertible in the field from one position to another, and is stabilized with adjustable rigging extending to the bow of the boat.
