摘要： A watersport propulsion system for a marine watersport vessel includes a drive unit arranged rotatable from a rearward-facing position to a forward-facing position, and vice versa, a control unit being operatively connected with the drive unit. The control unit is configurable in a nominal mode of operation and in a watersport mode of operation. The control unit is configured to operate the drive unit in the forward-facing position when in the watersport mode of operation and in the rearward-facing position otherwise.

摘要： Objects of the present invention are provide an evaluation method of ship propulsive performance in actual seas, an evaluation program of ship propulsive performance in actual seas and an evaluation system of ship propulsive performance in actual seas capable of precisely evaluating ship propulsive performance in actual seas on the same scale also before the ship sails for example. As solving means of the objects, a standard sailing model 2 of the ship in actual seas is set, a sailing condition of the ship and a ship condition of the ship are input to the standard sailing model 2, the standard sailing model 2 into which the sailing condition and the ship condition are input and the ship condition are applied to a previously verified calculating method 1 of ship performance in actual seas, and ship propulsive performance in actual seas is evaluated.

摘要： A remote-control unit for control a marine vessel is provided with a thruster actuator and engine actuators. When the marine vessel lacks a thruster, the thruster actuator, when operated, causes the remote-control unit to transmit engine control signals to each of at least two engines to achieve a virtual thruster effect by the marine vessel.

摘要： 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.

摘要： A controller for a watercraft controls first and second marine propulsion devices to start moving the watercraft by setting a first default angle, a second default angle, and a default thrust ratio as a first target rudder angle, a second target rudder angle, and a target thrust ratio respectively when a desired motion of the watercraft is straight sideways movement. The controller determines at least one of a first correcting angle, a second correcting angle, and a correcting thrust ratio to reduce an error between the straight sideways movement of the watercraft and an actual motion of the watercraft. The controller corrects the first target rudder angle, the second target rudder angle, and the target thrust ratio with the first correcting angle, the second correcting angle, and the correcting thrust ratio, respectively. The controller repeatedly detects the error and repeatedly updates the correcting angles and the correcting thrust ratio.

摘要： A method for controlling low-speed propulsion of a marine vessel powered by a marine propulsion system having a plurality of propulsion devices includes receiving a signal indicating a position of a manually operable input device movable to indicate desired vessel movement within three degrees of freedom, and associating the position of the manually operable input device with a desired inertial velocity of the marine vessel. A steering position command and an engine command are then determined for each of the plurality of propulsion devices based on the desired inertial velocity and the propulsion system is controlled accordingly. An actual velocity of the marine vessel is measured and a difference between the desired inertial velocity and the actual velocity is determined, where the difference is used as feedback in subsequent steering position command and engine command determinations.

摘要： Example systems and methods are provided herein for controlling a watercraft in response to a bite on a fishing line. A system includes a memory and a processor, and the processor is configured to receive data via user input or one or more sensors to determine whether a fish has bitten on a fishing line. In response to a determination that the fish has bitten on the fishing line, the processor causes the watercraft to operate according to a fish-on operation, which includes at least one of altering a speed of the watercraft, altering a direction of the watercraft, altering a rate of change of the speed of the watercraft, altering a direction of a trolling motor, notifying other watercrafts, or engaging an autopilot to navigate the watercraft according to a preset route. The fish-on operation is designed to aid a user in catching the fish.

摘要： In a ship control system of one embodiment, a main engine controller performs, when controlling the rotational frequency of a main engine based on a target ship speed of a ship, feedback control of an actual ship speed of the ship to perform ship speed control for bringing the actual ship speed closer to the target ship speed. A turning judgment unit judges whether or not the ship will turn. A control change unit performs, when the turning judgment unit has judged that the ship will turn, lowering processing for lowering the responsiveness of the ship speed control.
