ABSTRACT:
A water-skier towrope-handling system is provided that provides an alarm to the driver of a ski towboat when the skier falls. The alarm is triggered by the release of the towrope handle by the skier, independent of the tension on the ski rope. Preferably, a back-up switch is provided that activates the alarm upon contact with the water. The back-up switch is mounted on the towrope in close proximity to the handle assembly to signal the boat driver that the towrope handle assembly is in the water. The monitoring system also provides a tracking system that provides signals to the boat driver of the skier's position relative to the towboat. Preferably, the position indicator is frozen at the time of a fall to indicate the relative position of the skier at the time of the fall to facilitate finding the downed skier. The towrope handling system can also be used to vary the length of the towrope without affecting the action of the alarm and position-monitoring devices.
