What does a slashing hand motion over the neck mean by a waterskiing participant?

A slashing hand motion over the neck by a waterskiing participant is a universally recognized signal indicating that the boat operator should cut the motor or stop. This gesture communicates an urgent need to halt activity, often due to a fall or an emergency situation on the water. By performing this motion, the skier effectively grabs the attention of the boatdriver, ensuring that safety comes first.

This signal is crucial because it allows for a quick and clear understanding of the skier's need for immediate action, which might not be easily conveyed verbally due to the noise of the motor or the distance between the skier and the driver. Understanding this signal is essential for both the skier's safety and the overall safety of everyone on the water.
