What is the primary reason for using a lanyard on a personal watercraft?

The primary reason for using a lanyard on a personal watercraft (PWC) is to attach the engine cutoff switch to the operator for safety. This lanyard acts as a vital safety mechanism; if the operator falls off the PWC or is thrown from it, the lanyard will detach from the operator and trigger the engine cutoff switch, immediately shutting off the engine. This feature is designed to prevent the watercraft from continuing to operate without a driver, which could lead to accidents or collisions.

The significance of this safety measure cannot be overstated, as it protects not only the operator but also others in the vicinity on the water. By ensuring that the PWC stops operating when the operator is no longer in control, the lanyard helps to promote safer boating practices and reduce the risk of injuries or accidents on the water.
