What is the primary function of a boat’s kill switch?

The primary function of a boat’s kill switch is to shut off the engine if the operator falls overboard. This safety feature is crucial because it helps prevent accidents that could occur if the boat were to continue running without a pilot. When the operator is thrown from the vessel, the kill switch, which is typically connected to the operator via a lanyard or switch, gets activated. This immediately cuts power to the engine, bringing the boat to a halt. This feature is vital for reducing the risk of injury or further accidents in the event of an operator falling overboard. It underscores the importance of safety measures in boating practices, ensuring that the vessel does not continue operating uncontrolled.
