Abstract
An improved downed water skier warning system for alerting the operator of a skier tow-boat and the operators of nearby boats when a skier falls into the water or releases the skier towrope. The system includes electronic water sensors for sensing when the rope-handle of the skier tow-rope lands in the water, and pressure sensors for sensing when the water skier releases the rope handle. The water and pressure sensors are in remote communication with audible and visual tow-boat operator alarms and visual "skier-down" warning indicators, for enabling said alarms and indicators when a "downed skier" situation occurs. The improved warning system is designed for use in conjunction with marine warning devices and indicators commonly available, such as the "skier-down" flag and bow or stem directional lights.
