ABSTRACT:
A water ski brake apparatus includes a water ski having a tip, a tail, and a top and bottom, and having a vane attached to the bottom of the water ski. The water ski has a ski boot having a toe and heel with the front of the heel being hingedly attached to the top of the water ski. A drag inducing foil is movably attached to the vane in a predetermined position thereon and is shiftable between first and second angular positions. A linkage is attached to the boot heel at one end and to the drag inducing foil at the other end and is shiftable between a first and second position responsible to movement of the boot heel on the boot hinged to shift the drag inducing foil between first and second positions to thereby brake the water ski by increasing the drag when the drag inducing foil is shifted to a second position in the water at the control of the skier by varying his weight distribution in the heel portion of the boot.
