Abstract:

A device for use on ski boats is disclosed which provides a warning to other boats in the area that a downed water skier is in the water by using a motorized electrical device to raise a flag, either automatically when a skier falls and the tow rope is released, or manually when triggered by the motor boat operator or passenger. The device electrically raises the warning flag, and maintains it in an upright position until the skier grasps the tow rope handle, or until the operator releases the manual trigger switch, at which time the flag is returned to a lowered position by a spring. The system of the present invention may be used with one or more water skiers, and uses a positive switch indicator rather than depending on the degree tension in the tow rope.
