Abstract
An automatic timing measurement system provides a measure of time of passage of a watercraft through a prescribed course. Inertial or other estimates augmented by GPS speed/position measurements are used to track position of a watercraft, and those estimates are used to allow the locations of prescribed courses to be mapped and memorized. The apparatus may automatically detect passage of a watercraft through mapped courses for the purpose of measuring and reporting time of passage past key points in the course, and for modifying the behavior of the speed control of the apparatus if necessary at certain points in the mapped course. GPS speed control may be augmented with a secondary velocity measurement device that measures speed over water resulting in an optional user selectable real-time compensation for water current. Furthermore, GPS may be used as the key input to produce boat speed-based pull-up profiles.
