The Coast Guard Office of Commercial Vessel Compliance published a marine safety information bulletin concerning operations involving water jet devices, or WJD.
For the purposes of the MSIB, the acronym “WJD” includes Jetpaks™, Jetlevs™, Flyboards™, Jetovators ™, HydroliftTM and JetsurfTM, and other similar devices where individuals ride a hydro-powered apparatus above the surface of the water while connected to a personal watercraft or other power source that supplies thrust to the WJD through a hose connecting the two devices.
The bulletin identifies where a passenger for hire operation exists, the licensing requirements and the safety-related procedures specifically for navigable waters over which the Coast Guard has jurisdiction.
