摘要： A stowable propulsion system for a marine vessel. A base is configured to be coupled to the marine vessel. A propulsion device is configured to propel the marine vessel in water. A shaft extends along a length axis and pivotably couples the propulsion device to the base. The propulsion device is pivotable into and between a stowed position and a deployed position, wherein pivoting the propulsion device causes the shaft to rotate about the length axis.

摘要： A tiller for an outboard motor has a tiller body that is elongated along a longitudinal center axis between a proximal end and a distal end, a throttle grip on the distal end of the tiller body, and a control switch located on the tiller body adjacent the throttle grip. A microcontroller is located inside the tiller body, remote from the control switch, and is in signal communication with an engine controller of the engine. The control switch is configured to be selectively electrically connected to the microcontroller. In response to actuation of the control switch, the microcontroller sends a signal to the engine controller. In one example, the control switch is an idle speed control switch.

摘要： To improve prediction accuracy in model predictive control.
The ship control device includes processing circuitry. The processing circuitry estimates an initial search value of a throttle opening by an estimation method based on uncertainty with a distance between a position of the ship and a target position of dynamic positioning, and a true wind velocity as preconditions. The processing circuitry searches an action for moving the ship to the target position by a model predictive control in a search range having the initial search value as an origin, and determines a command throttle opening based on the search result.

摘要： A ship speed control system includes: a ship speed deviation calculation module which calculates a ship speed deviation based on the difference between an actual ship speed and a ship speed target value; and an input gain adjustment module which adjusts a gain input to a throttle control function to a first gain value when the ship speed deviation is not less than a first threshold value, and adjusts the input gain to a second gain value which is larger than the first gain value and smaller than the initial gain value when the ship speed deviation is not less than the first threshold value and not less than the second threshold value.

摘要： A marine vessel control system operable to be used with a shallow water anchor and a motor. The marine vessel control system comprising a memory and a processor. The processor is configured to receive a user command to maintain a position of a marine vessel, receive sonar data, determine a water depth relative to a water bottom based on the sonar data in response to receiving the user command, and transmit a command to use the shallow water anchor and/or the motor based on the water depth.

摘要： A stowable propulsion system for a marine vessel. A base is configured to be coupled to the marine vessel. A shaft has a proximal end and a distal end with a length axis defined therebetween, where the shaft is pivotably coupled to the base and pivotable about a transverse axis between a stowed position and a deployed position, and where the distal end is closer to the marine vessel when in the stowed position than in the deployed position. A gearset is engaged between the shaft and the base, where the gearset rotates the shaft about the length axis when the shaft is pivoted between the stowed position and the deployed position. A propulsion device is coupled to the distal end of the shaft. The propulsion device is configured to propel the marine vessel in water when the shaft is in the deployed position.

摘要： The control method of a ship is used for the ship. The ship is equipped with a plurality of power sources including a first power source and a second power source, and has a plurality of propulsion modes in which a power source used for propulsion of a hull is different between the plurality of power sources. The control method of the ship includes adjusting an output value related to a propulsive force of a hull to a value corresponding to an operation amount of an operation acceptor and changing a correspondence relation between the operation amount and the output value in accordance with a propulsion mode.

摘要： A method for using a system including a plurality of first fields and a plurality of second fields fixed to a first device and presenting a first physical characteristic and a second physical characteristic, respectively, the first and second fields being arranged in an alternating manner. First and second sensors are fixed to the second device and arranged to move along the array of fields when the second device moves in relation to the first device. The method includes detecting, by the first sensor and during a movement of the second device in relation to the first device, a transition from the first to the second physical characteristic, or vice versa, simultaneously detecting, by the second sensor, the first or the second physical characteristic, and determining, based on the detected transition and physical characteristic, the direction of movement of the second device in relation to the first device.
