A remote display device includes processing circuitry. The processing circuitry display a display screen. The processing circuitry generate a plurality of display data corresponding to mutually different display areas, each being a part of the display screen. The processing circuitry transmit the plurality of display data generated to a plurality of terminal devices, respectively. The processing circuitry update the display screen based on operation data indicative of an operation performed by the terminal device to the display area corresponding to the display data.

A boat maneuvering control method for a boat includes acquiring target route information and information about an actual position of the boat, setting a target position based on the target route information and the information about the actual position, acquiring, as a deviation amount, a distance between the target position and the boat in a predetermined direction that intersects with a target route, and controlling a magnitude of a propulsion force of a propulsion device so as to reduce the deviation amount.

The present invention provides an auxiliary berthing method and system for a vessel. In the berthing method, by a solar blind ultraviolet imaging method, a position and an attitude of a vessel relative to a shoreline of a port berth during berthing are calculated by at least two solar blind ultraviolet imaging modules according to light signals received by a solar blind ultraviolet light source array arranged in advance on the shore. Further, when more than three solar blind ultraviolet imaging modules are used, in the method and device of the present invention, a normalized correlation algorithm and a data fusion algorithm are used to improve the accuracy of the position and attitude data of the vessel.

Artificial-intelligence-based river information system. In an embodiment, a first training dataset is used to train a travel time prediction model to predict a travel time along the waterway for a given trip. In addition, a second training dataset is used to train a river level prediction model to predict a river level along the waterway for a given time. For each of a plurality of trips, a request is received that specifies the trip and a time of the trip, and, in response to the request, the travel time prediction model is used to predict a travel time for the trip, and the river level prediction model is used to predict a river level of the waterway at one or more points along the trip. Then, a voyage plan is generated based on one or both of the predicted travel time and the predicted river level.

A marine vessel fuel control system may comprise an interface to receive data identifying the vessel and data identifying a voyage to be undertaken by the vessel. The control system may also comprise a memory to store program code to implement a predictive model and parameter values for the model, the values resulting from an optimisation of the model using historical data for marine vessels and voyages. The control system may also comprise a processor arranged to execute the program code to: instantiate the model using the values; supply the data identifying the vessel and the data identifying the voyage to be undertaken to the model; and apply the model to determine a fuel consumption estimate for the vessel for the voyage. A fuel supply system determines an amount of fuel to be supplied to at least one fuel tank of the vessel based on the fuel consumption estimate.

A system for a traveling history report of a personal watercraft includes processing circuitry. The processing circuitry is configured to: generate traveling history data based on positional information indicating a position of the personal watercraft, the traveling history data including information indicating a movement route of the personal watercraft; and output the traveling history data.

The purpose of the present disclosure is to set the initial information of the anchoring object (target) of a ship with high accuracy. A ship navigation assistance system according to the present disclosure includes a provisional initial information specifier, a measurement sensor and processing circuitry. The provisional initial information specifier may accept a specification of provisional initial information for characteristic information on an object to which a ship anchors or docks (docks to a pier). The measurement sensor may acquire measurement information on an object using a ranging result of an area including the object.

A water area object detection system includes a first imager to image an object around a hull, a second imager provided on the hull such that an imaging direction of the second imager is the same or substantially the same as an imaging direction of the first imager and operable to image the object around the hull, and a controller configured or programmed to perform a control to create a water area map around the hull based on images captured by the first imager and the second imager. The second imager is spaced apart in an upward-downward direction of the hull from the first imager, and the first imager is spaced apart in the imaging direction from the second imager so as not to overlap the second imager in the upward-downward direction perpendicular to the imaging direction.

A water area object detection system includes an imager to capture an image around a hull, and a controller configured or programmed to perform a control to detect a feature point corresponding to an object in the image together with a distance to the feature point based on the image captured by the imager to create a water area map in which an object presence range including a likelihood that the object is present is set around the feature point. The controller is configured or programmed to reduce the object presence range as the distance from the imager to the feature point decreases, and set a size of the object presence range to a lower limit when the distance from the imager to the feature point is equal to or less than a predetermined distance.

A navigation information device is provided with a position acquisition unit for acquiring a position information of its own ship, a memory for storing display settings corresponding to a waypoint that is a via point on a planned route, and a display processing unit for performing generation processing for generating a screen in which the position information is superimposed on a chart, and performing change processing for changing display settings to display settings corresponding to the waypoint based on a positional relationship between the position information and the waypoint.
