A moving body control device includes a moving body direction sensor, a position sensor, and processing circuitry. The processing circuitry estimates a direction of disturbance. The processing circuitry sets a target position and a starting position. The processing circuitry controls a propulsion generator and a movement direction adjuster such that a heading direction sensed by the moving body direction sensor is opposite to the direction of the disturbance estimated by the processing circuitry, and when the moving body has been drifted at least a specific distance from the target position, the moving body returns to the starting position, and the heading direction at the starting position is opposite to the direction of the disturbance. The processing circuitry changes the starting position based on a distance between the target position and a position of the moving body sensed by the position sensor.

A ship assignment device acquires voyage schedule information including an operation time schedule and a sailing route of a voyage. The ship assignment device acquires, from a database, weather information related to the operation time schedule and the sailing route included in the schedule information. The ship assignment device acquires information regarding variations in fuel consumption rate from a database that stores the information for each of plural ships. On the basis of the acquired weather information and acquired information regarding each ship, the ship assignment device calculates the fuel consumption for when each ship sails on the sailing route included in the acquired voyage schedule information in accordance with the operation time schedule included in the voyage schedule information. On the basis of the calculation result, the ship assignment device outputs information identifying plural ships.

Techniques are disclosed for systems and methods to provide remote sensing imagery for mobile structures. A remote sensing imagery system includes a radar assembly mounted to a mobile structure and a coupled logic device. The radar assembly includes an orientation and position sensor (OPS) coupled to or within the radar assembly and configured to provide orientation and position data associated with the radar assembly. The logic device is configured to receive radar returns corresponding to a detected target from the radar assembly and orientation and/or position data corresponding to the radar returns from the OPS, determine a target radial speed corresponding to the detected target, and then generate remote sensor image data based on the remote sensor returns and the target radial speed. Subsequent user input and/or the sensor data may be used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.

Techniques for providing instructions to an operator of a sea vessel via a computing device are described. The computing device can request, from another computing device, instructions regarding one or more of an intended course and action plan for the sea vessel, which can include at least one navigational instruction and/or deployment instruction. The computing device can send data to a display device to cause a prompt to be displayed. The prompt can include options regarding the at least one instruction. The computing device can send state information of the sea vessel to the other computing device. The state information can include the received input and location information of the sea vessel. Additionally, data can be received by the computing device from a shore based operator and data can be sent to one or more clients on shore.

A system and method for predicting, forecasting and suggesting voyage plans for a vessel by considering design parameters, weather in sailing routes and a user's preference for best weather or best economy or fastest way to reach the destination. Voyage plans are optimized using the above parameters, and directions are continuously provided in the form of heading and speeds to be maintained by the vessel during the course of the voyage.

The present invention discloses a vessel collision avoiding system and method based on Artificial Potential Field algorithm, the method comprises the following steps: (S1) obtaining a vessel information, at least one obstacle information and a target information; (S2) establishing an Artificial Potential Field (APF) by the vessel information, the at least one obstacle information and the target information, wherein the Artificial Potential Field comprises an attractive field of the target and a repulsive field of the obstacle; (S3) combining the attractive field and the repulsive field to obtain a first resultant force; (S4) Adding an external force to the Artificial Potential Field based on the vessel information or the obstacle information; (S5) combining the first resultant force and the external force to obtain a second resultant force; and (S6) the vessel sails in the direction of the second resultant force to avoid the obstacle.

Systems and methods for conveniently providing anchoring assistance onboard a watercraft are provided herein. An example system includes a display and a processor in communication with a marine system. The processor is configured to receive marine data from the marine system and/or one or more user inputs and cause the display to show one or more anchoring locations with visual indications of the anchorage quality index based on at least the marine data and/or user inputs. The one or more anchoring locations may be shown as a heat map overlaid on a map. The system may use real-time marine data, environmental data, weather data, tide data, etc. to dynamically adjust the anchoring locations and anchorage quality index. The system may enable convenient and helpful suggestions and notifications to the user when anchoring a watercraft. Some examples provide automatic deployment of an anchoring system and monitoring of a current anchoring.

Various implementations described herein are directed to an apparatus for displaying marine electronic navigation data. The apparatus comprises one or more processors, a screen configured to display marine data, and a memory having a plurality of executable instructions. The executable instructions, when executed by the one or more processors, may cause the one or more processors to determine a location of a vessel and at least one of a heading or a projected direction of travel of the vessel, retrieve a bathymetric chart corresponding to the location, analyze the bathymetric chart, the location, and the at least one heading or projected direction of travel of the vessel to determine a plurality of depths that each correspond to one of a plurality of locations corresponding to the heading or the projected direction of travel of the vessel, and display the plurality of depths on the screen.

A boat sharing system includes a non-transitory computer readable memory for receiving and storing data for routes previously traveled. The route data includes starting and ending points and points of interest along the routes. The memory receives and stores data related to boat types, equipment for boating activities and boat drivers. A processing system accesses the memory and is configured to: display the stored data; receive and store route data and trip timing, boat type, equipment, boat driver requirements and activity desires for a present user; compare the present user's desired route, timing, activity, equipment and boat driver requirements with previously stored data. The system provides at least one previously stored set of route, boat, activity, equipment and operator data as an option for the present user; provides proposed timing, starting and ending points for the suggested route; and permits the present user to confirm selection of the suggested route.
