What do you need to observe when towing a water skier?

When towing a water skier, it is essential to have a competent observer onboard in addition to the operator. This is critical for safety and effective communication during the activity. The observer's role is to keep a constant look at the skier, ensuring that they are safe and helping the operator by providing timely signals or alerts regarding the skier’s position or condition. This dual presence helps prevent accidents and allows for immediate response if the skier falls or encounters difficulty.

Regarding the other options, a skier must ideally wear a life vest that meets safety regulations, but simply stating that they must wear one without considering quality and design does not encapsulate all safety requirements. Speed limits apply in towing activities to ensure the safety of all individuals involved and to comply with local regulations. Additionally, the tow rope length must meet safety guidelines, typically not being less than 50 feet, as a rope that is too short can pose risks to the skier and operator.
