ABSTRACT:
A signaling device for raising a warning flag or pennant deployed on a motor boat to indicate that a water skier towed by the boat has fallen is disclosed which reliably raises a flag either manually when triggered by the motor boat operator or passenger, or automatically when the tow rope is released, thereby indicating to other boats in the vicinity that the water skier has fallen into the water. The heart of the device is a gear motor assembly operated by a DC motor, which is used to drive a flag pole containing a flag between lowered and deployed positions. Movement of the gear motor assembly is limited to ninety degrees by two micro switches, which remove power to the motor when an extreme position is reached.
