Personal watercraft must comply with all rules and regulations applicable to powerboats. There are additional rules and regulations for personal watercraft operators as follows: A boat is a motorboat less than 16 feet in length that uses an inboard motor that drives a jet pump as the main propulsion force and is designed to be operated by a person sitting, standing or kneeling, rather than the traditional way of sitting or standing in the ship. The foregoing provisions do not apply to participants in regattas, races, naval parades, tournaments or exhibitions approved by the VDGIF or USCG Board of Directors.
