Methods and systems for operating powersport vehicles during an operator-vehicle separation condition are provided. One method includes detecting the operator-vehicle separation condition using a first tetherless criterion and a second tetherless criterion. In response to detecting the operator-vehicle separation condition using both the first tetherless criterion and the second tetherless criterion, the method includes preventing propulsion of the powersport vehicle.

A periphery recognition support system for a personal watercraft includes processing circuitry. The processing circuitry is configured to: receive position related data related to a positional relation between a personal watercraft and a peripheral object around the personal watercraft; determine based on the position related data whether or not a predetermined warning condition is satisfied; and output a predetermined warning signal when it is determined that the warning condition is satisfied.

A self-propelling watercraft system is provided. The watercraft has a base with a plurality of sidewalls extending from the base to form a cockpit. The base also has a recess, where a pump can detachably connect to the hull within the recess. The pump has an intake valve on a first end and a nozzle on a second end that is opposite the first end. The intake valve can intake water. The nozzle can jettison water received in the pump from the intake valve and agitate water surrounding the nozzle.

A control device of a marine vessel includes a wireless master unit to wirelessly communicate with a wireless slave unit possessed or worn by a vessel operator, and a processor configured or programmed to function as a detecting unit to detect that an engaging portion of a lanyard connectable to a connecting portion provided on a hull of the marine vessel is detached from the connecting portion, an obtaining unit to obtain a physical quantity that indicates at least one of a rotation speed of a drive source that propels the hull and a vessel speed, a judging unit to judge a state of wireless communication between the wireless master unit and the wireless slave unit, and a control unit to control the drive source based on a detection result obtained by the detecting unit, the physical quantity obtained by the obtaining unit, and a judgment result obtained by the judging unit.
