A personal flying water jet board system includes a jet board with a water jet propulsion system. A water intake system mounted on either side of a boat includes an intake member submerged in the water and connected to a hose which is connected to jet nozzles of the jet board. The water injected into the jet nozzles propels the jet board and user above the water. A water intake system mounted on the boat is fluidically connected to the hose and directs water into the jet nozzles. Water-conducting support pipes have intake members with an intake end oriented towards the forward end of the boat to receive water as the boat moves forward and a discharge end. The intake end of the intake member is shaped to increases the water pressure as the water flows into the discharge end thereof and into the water-conducting support pipes.

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 propulsion device includes a platform with a pair of elbowed tubular thrust nozzles respectively located on opposite sides of the platform. An input end of each nozzle is mounted to the platform and rotatable about a transverse axis that is normal to a longitudinal axis of the platform, and is connected to a source of pressurized fluid. A pair of actuators are respectively connected to the tubular nozzles to rotate the nozzles around the transverse axis and thereby change the orientation of output ends of the nozzles relative to the platform. A processor controls the position of the platform by activating the actuators to rotate the nozzles, and thereby change the direction of thrust emitted by the pressurized fluid at the output ends of the nozzles.

A motorized, steerable, electrically-operated personal watercraft that includes a hull with a bow, stern, top deck surface, underside surface, and a support and steering console. The deck is configured to allow a user to lie prone on the deck with the user's chest located on or proximate the console. There are left and right steering control devices located at the left and right of the console, respectively. The steering control devices are configured to be manipulated by the left and right hands of the user. Motive power and steering are both provided through an electrically-powered water jet, which may be but need not be located at the stern. The water jet is mounted to a fixture that is configured such that the outlet nozzle of the jet can be turned left and right, in order to steer the craft to the left and right. Jet nozzle steering is accomplished by manipulation of the left and right steering controls. User-operable kill switches also located at the left and right of the console must be operated in order to operate the jet.
