A vessel propulsion apparatus includes a first transmission path that transmits the power of an engine to a propeller shaft, a second transmission path that transmits the power of a motor to the propeller shaft, and a controller. A first clutch cuts off the power transmission of the first transmission path in a first disconnection state, and permits the power transmission of the first transmission path in a first connection state. A second clutch cuts off the power transmission of the second transmission path in a second disconnection state, and permits the power transmission of the second transmission path in a second connection state. The controller executes tuning control of both the engine and the motor when the first clutch is switched between the first disconnection state and the first connection state and when the second clutch is switched between the second connection state and the second disconnection state.

A control device for a vessel, the control device comprises: an operation monitoring unit configured to monitor presence or absence of a supply of first electric power supplied from a power supply to an operation display unit for operating the vessel; a drive monitoring unit configured to monitor presence or absence of a supply of second electric power supplied from the power supply to a drive source of the vessel; and a caution control unit configured to cause a caution output device to output a caution based on information indicating the presence or the absence of the supplies of the first electric power and the second electric power that have been respectively acquired from the operation monitoring unit and the drive monitoring unit.

A watercraft of an automatic maneuvering system includes an actuator configured to generate a propulsive force and a turning moment, an operation unit, and a watercraft control device.

A controller controls a shift operation of a propulsion device between forward, neutral, and reverse, and steering of the propulsion device in accordance with a tilt operation of a joystick. The controller stores a control state of the propulsion device according to the tilt operation of the joystick when a switch is operated. The controller maintains the propulsion device in the control state even when the joystick is returned to the neutral position.

An apparatus comprising one or more propulsion units that are operable to help propel a user in water. The propulsion units are battery operated, such as with a rechargeable battery, and are selectively operable to create a propulsion force in water. The propulsion force propels the apparatus in water. A person wearing the apparatus, such as in the form of a vest, is propelled in water with the apparatus.

Control system for controlling operations of a marine vessel having a first engine and a second engine is provided. Parity switches are operable to start/stop first and second engine. Each parity switch is actuated for first time to activate remote start/stop control of respective engine. Each switch is actuated for second time to switch respective engine to ON or OFF state. Operator console is communicatively coupled to parity switches to receive first and/or second user inputs. Propulsion control unit is communicably coupled to operator console via network communication channel, first engine control unit of first engine and second engine control unit of second engine. Propulsion control unit receives operational parameters for engines from engine control units and receives first and second user inputs from operator console. Propulsion control unit transmits engine operating signals for operating respective engines in response to first and/or second user input and based on operational parameters.

The present disclosure generally relates to a joystick device (100) operable to provide speed, direction and steering commands for controlling a marine vessel (300). The present disclosure also relates to a marine propulsion control system controlling a set of propulsion units (308, 310, 312 and 314) carried by a hull of a marine vessel (300), wherein the marine propulsion control system is adapted to receive an input command from such a joystick device (100).

A marine vessel to transmit a rescue signal includes a hull, a propulsion force generator to generate a propulsion force to propel the hull, and a controller. In the marine vessel, the controller is configured or programmed to acquire vessel speed information regarding a vessel speed of the hull, and determine whether or not rescue is necessary based on the vessel speed information in a case where operation of the propulsion force generator is stopped.

A watercraft has a retractable lift-propulsion system including a mast connected to a buoyant body of the watercraft and movable between retracted and deployed positions. A distance between a distal end of the mast and a lower surface of the buoyant body is greater in the deployed position than in the retracted position. A lift-propulsion assembly includes a hydrofoil for providing lift to the watercraft at least in the deployed position of the mast and a propulsion unit for providing thrust to the watercraft in the retracted and deployed positions of the mast. The lift-propulsion assembly is connected to the distal end of the mast such that, in the deployed position of the mast, the lift-propulsion assembly is distanced from the buoyant body of the watercraft and, in the retracted position of the mast, the lift-propulsion assembly is proximate the buoyant body of the watercraft.

An apparatus and method for use with a marine vessel having a first steerable propeller and a second steerable propeller is disclosed. The apparatus and method providing for movement of the first and second steerable propellers relative to each other and also maintains a minimum distance between the first and second steerable propellers so as to prevent the first and second steerable from contacting each other. Also disclosed is a control system and method to control the first steerable propeller and the second steerable propeller to provide the fixed distance between the first and second steerable propellers and so as to individually control the first steerable propeller and the second steerable propellers to allow the first steerable propeller and to the second steerable propeller to move relative to each other.
