Abstract
A self-halt device for water-jet, power-driven water craft is disclosed, which includes a duct connected at a forward end thereof to the atmosphere and, at its opposite end, to a water passage defined in the rear bottom of the water craft in which a propeller is connected to an engine through a propeller shaft. A valve is installed in the duct, which closes or opens the duct in response to sensing the weight of a driver properly sitting in or standing on a driver seat mounted on top of the water craft deck. With the valve in its operating position where the duct is closed, the engine rotates the propeller in the water passage filled with water which is discharged in a jet from the stern. When the pressure is removed from the driver seat, as when the driver was inadvertently displaced from board, the valve is actuated to open the duct permitting atmospheric air into the water passage, so that engine rotates the propeller on air. Thus, the water craft is brought to a halt, without stopping the engine, within easy reach of the displaced user who can swim over and recapture the water craft.
