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

A slashing hand motion over the neck is a universally recognized signal in waterskiing that indicates to the boat operator to cut the motor or stop immediately. This gesture serves as a clear and urgent communication method for participants on the water to signify a critical situation or potential danger, such as falling or needing immediate assistance. The movement is distinct and easily interpreted from a distance, ensuring that the message is conveyed quickly and effectively to prevent accidents or further conditions that could lead to injury.

While there are other signals for different situations, the slashing motion specifically relates to the need to halt operations to ensure the safety of those participating in the activity. In contrast, the other options represent different meanings that do not correspond to this particular motion.
