In New York State, you must be at least 18 years old to operate a personal watercraft (Jet Ski, WaveRunner, Sea-Doo, etc.) without an adult (18+) onboard.
PWCs are fast, nimble, and offer little protection. Statistics show younger operators have disproportionately higher accident rates. The age floor aligns with NY's graduated responsibility approach for motorized recreation.
Violations can mean fines ($100–$250), certificate suspension, or liability in accidents. Always check the latest NYS Parks & Recreation marine law summary before hitting the water.
