Abstract

A timing system for providing consistent tow times in waterskiing competition by determining the position of the tow vehicle on the course relative a reference time and method of use are disclosed. The timing system includes timing means for indicating intermediate elapsed reference times that a tow vehicle would have if it was completing the course within the required time and speed tolerences, acutating means, electrically connected to the timer, for synchronizing the start of the timer with the entry of the vehicle on the course, and a communicator, electrically connected to the timer, to provides cues to the operator for comparison with the tow vehicle'"'"'s actual position on the course. Methods for determining the position of the tow vehicle are also disclosed.

Claims

1. A system for determining the position of a tow vehicle relative an intermediate reference point along a predetermined course comprising:

timing means;

actuating means for selectively starting said timing means, said actuating means electrically conected to said timing means; and

communicating means for indicating the appropriate time for said tow vehicle to be at said intermediate reference point of said predetermined course, said communicating means electrically connected to said timing means.

2. A system for determining the position of a tow vehicle along a predetermined course as set forth in claim 1, wherein said timing means includes means indicating intermediate reference times corresponding to traveling between respective intermediate reference points along said predetermined course.

3. A system for determining the position of a tow vehicle along a predetermined course as set forth in claim 1, wherein said actuating means includes a remote actuator, said remote actuator electrically connected to said timing means.

4. A system for determining the position of a tow vehicle along a predetermined course as set forth in claim 1, wherein said communicating means includes a cue generator for communicating the completion of each said intermediate reference times.

5. A system for determining the position of a tow vehicle along a predetermined course comprising:

timing means, wherein said timing means includes means indicating intermediate reference times corresponding to respective intermediate reference points along said predetermined course;

means for selectively actuating said timing means wherein said means for selectively actuating said timing means includes a remote actuator, said remote actuator electrically connected to said timing means; and

communicating means for indicating the completion of each intermediate reference time for said tow vehicle to be at said respective intermediate reference points, where in said communicating means includes audio means for communicating the completion of each said intermediate reference times.

6. A system for regulating the speed of a tow vehicle in conjunction with a predetermined course having a beginning and intermediate reference points, said system comprising:

means for determining the position of said tow vehicle along said course;

means for indicating intermediate reference times corresponding to said intermendiate reference points;

means for synchronizing the position of said tow vehicle along said course with said intermediate reference times; and

means for communicating the passage of said intermediate refernce times.

7. A system for regulating the speed of a tow vehicle as set forth in claim 6, wherein said means for determining the position of the tow vehicle includes sight means on said tow vehicle for determining the position of said tow vehicle relative said intermediate reference points.

8. A system for regulating the speed of a tow vehicle as set forth in claim 6 wherein said means for synchronizing the position of said tow vehicle along said course includes acuator means for starting said means for indicating intermediate reference times at said begining of said predetermined course.

9. A method for regulating speed of a tow vehicle along a predetermined course comprising the steps of:

laying out a pre-determined course with means to indicate position thereon;

determining intermediate reference times corresponding to that of said tow vehicle which traverses said course at a selected speed;

synchronizing said intermediate references time with traveling on said predetermined course; and

determining the position of said tow vehicle along said course with reference to said intermediate reference times.
