Slalom water-ski training and monitoring system for on-water use
First Claim
1. A water-ski performance measuring apparatus that determines a position of a water-skier relative to a boat, wherein the water-skier holds onto a rope extending from the boat, said performance measuring device comprising:
- angle measurement device that measures an angular displacement over time of a rope extending from a boat, wherein the angular displacement is measured from a predetermined centerline; and
a controller that correlates the measured angular displacement of the rope with a position of the boat.

Abstract
An apparatus for measuring the performance of a slalom water-skier and associated methods for interpretation of the data are disclosed. The apparatus consists of a means for measuring the angle of the water-ski tow rope relative to the boat and the tension of the water-ski tow rope. This data may be transmitted immediately or stored for later transmittal. The data are analyzed by calculating the time spent in the various regions of the slalom course, or by calculating how early or late the skier is for the individual buoys in the course.
