Disclosed is a method for controlling a hydrofoil board powered by a motor driven propeller. The motor is controlled by a hand controller configured with user selectable operating pre-sets including a first operating pre-set, wherein the board is accelerated to a first speed which is less than that required for the board to hydrofoil, and a second operating pre-set, wherein the board is accelerated to a second speed sufficient for the board to hydrofoil. Alternatively, the operating pre-sets may limit the motor power. A system for operating a hydrofoil board is also disclosed, which includes a propulsion control unit comprising a propulsion source, and a hand controller configured to receive a first user input and a second user input and to transmit the user inputs to the propulsion control unit.

An electromechanical lockout device for a remote control on a marine vessel includes an electric actuator and a locking pin having an engagement end and a second end. The locking pin is arranged with respect to a control lever such that the locking pin is positionable in a locked position, where the engagement end of the locking pin prevents rotation of the control lever into a reverse position, and in a retracted position, where the engagement end of the locking pin allows rotation of the control lever into the reverse position. A method of controlling lockout for a remote control includes sensing a position of a control lever, calculating a rate of change of the position, and engaging a lockout to prevent a gear system from shifting into reverse gear if the rate of change exceeds a threshold rate of change.

A modular, weight-shift controlled watercraft device is disclosed which includes: a modular board removably attachable to a power system. The power system includes a modular power supply system, and a modular propulsion system. The power supply system includes a housing including a battery. The propulsion system includes a modular strut, a modular propulsion pod, and a modular hydrofoil. In one embodiment, the power supply system is removably and mechanically attachable directly to the propulsion system.

A system for controlling a marine vessel having first and second waterjets, corresponding first and second steering nozzles and corresponding first and second reversing buckets. The system comprises a speed control device for providing a first vessel control signal that corresponds to a speed to be provided to the marine vessel, a processor configured to receive the first vessel control signal and that is configured to provide at least one first actuator control signal coupled to the first and second waterjets, and at least one second actuator control signal coupled to the first and second steering nozzles and the first and second reversing buckets. The system any of improves upon turns provided by conventional waterjet propulsion systems, improves upon slowing down or stopping marine vessels as is done by conventional waterjet propulsion systems, and improves upon the controllability of the waterjet propulsed marine vessel at low vessel speeds.

A system controls movement of a marine vessel near an object. The system includes a control module in signal communication with a marine propulsion system, a manually operable input device providing a signal representing a requested translation of the marine vessel, and a sensor providing a first distance between the vessel and a first point on the object and a second distance between the vessel and a second point on the object. The control module determines an actual angle between the vessel and the object based on the first distance and the second distance. In response to the signal representing the requested translation, the control module stores the actual angle between the vessel and the object as an initial angle and controls the marine propulsion system to produce thrust that will carry out the requested translation and that will maintain the initial angle.

A first outboard motor attached to a vessel body receives an electric operating signal and is controlled in accordance with the electric operating signal. A second outboard motor attached to the vessel body receives a mechanical operating amount and is controlled in accordance with the mechanical operating amount. An operating tool controls shifting and a throttle opening degree of each of the first and second outboard motors. The electric operating signal is transmitted through a first transmission path to the first outboard motor based on an operation of the operating tool. The mechanical operating amount is transmitted through a second transmission path to the second outboard motor based on an operation of the operating tool.
