Operators towing a person(s) on water skis or a similar device have specific equipment and observer requirements.
- Children 12 years old and younger being towed must wear a USCG–approved, appropriately sized Type I, II, or III PFD.
- Boats towing a person(s) on water skis or a similar device must carry on board a red or orange skier-down flag and display it whenever the skier is in the water.
- Every boat towing a person on water skis or a similar device must have a person, in addition to the operator, continuously observing the towed person.
- If the towing boat is a PWC, the PWC must be rated for at least three people—the operator, the observer, and the retrieved skier.
