Abstract: In one aspect, a wireless remote controller for a personal watercraft is provided that includes a watertight body and a rotatable thumbwheel disposed on an upper surface of the watertight body. The remote controller includes at least one magnet affixed to the thumbwheel such that the at least one magnet rotates with the thumbwheel. The remote controller includes a magnetic sensor configured to produce magnetic field data in at least two axes. The remote controller includes a processor operably coupled to the magnetic sensor and communication circuitry configured to communicate control signals to an associated personal watercraft. The processor is configured to determine an angular position of the thumbwheel based at least in part on the magnetic field data in each of the at least two axes and to generate a control signal based at least in part on the determined position of the thumbwheel.

Abstract: A flexible coupling mechanism may be used to suspend a structural component, such as a propulsion pod, from a support member, such as a strut of a hydrofoil watercraft. The flexible coupling mechanism may include multiple vibration isolating mounts configured to extend through the support member to suspend the structural component. The vibration isolating mounts may include a plurality of elastomeric bushings configured to prevent direct contact between a component rigidly coupled to the support member and a component rigidly coupled to the structural component. The elastomeric bushings may include a tapered outer profile configured to provide a nonlinear force feedback profile in response to rotation of the support member relative to the structural component.

Abstract: A fluid level sensing apparatus is disclosed having an electrode assembly, signal generating circuit, and signal processing circuit. The electrode assembly includes a first electrode disposed along an outer surface of the electrode assembly and a second electrode disposed along the outer surface of the electrode assembly, the second electrode separate from the first electrode. The signal generating circuit is configured to output a repeating pulse signal to the first electrode. The signal processing circuit is electrically coupled to the second electrode and configured to receive the signal conducted through the fluid from the first electrode to the second electrode when the electrode assembly is at least partially submersed in the fluid. The signal processing circuit is configured to output a voltage corresponding to a length of the electrode assembly that is submersed in the fluid based at least in part on the signal received by the signal processing circuit.

Abstract: A watercraft is provided that includes a support platform having a bottom surface. The watercraft includes a hydrofoil disposed on a strut extending from the bottom surface of the support platform. The watercraft includes a propulsion system coupled to the bottom surface of the board such that a thrust generated by the propulsion system moves the board through a body of water. The watercraft includes a position sensor, a speed sensor, and an altitude controller. The position sensor is configured to output position data of the watercraft relative to a surface of water. The speed sensor is configured to output speed data of the watercraft. The altitude controller is configured to adjust the thrust generated by the propulsion system based at least in part on a ride height derived from the position data and a speed derived from the speed data to achieve a target ride height.

Abstract: In one aspect, a wireless remote controller for a personal watercraft is provided that includes a watertight housing forming a watertight compartment.
