A system for guiding a boat, which includes the boat and a remote server. The boat includes a central unit linked to a user interface, a receiver for receiving data transmitted by at least one electronic tag affixed to a device of the boat and to a radio device for bidirectional communication with the remote server. The central unit transmits information resulting from the data transmitted by the tags, the current position and the route plan of the boat via the radio device to the server, and receives route plan modification data, which are displayed on the user interface, from this server. In this way, the operator of the boat is able to gain knowledge of the movement of nearby craft and of possible collision risks. Further, the boat may include on-board connected objects that communicate with the central unit in order to determine whether devices are missing on board.

A speed control device which is satisfactory in response and tracking to a speed setting, and can adjust an acceleration-and-deceleration feel according to preferences, is provided. The speed control device 6 controls a speed of a ship so that the speed automatically follows a speed setting set by a ship operator. The speed control device 6 includes a target speed setting module 63 and a change rate adjusting module 64. The target speed setting module 63 sets a target speed that is a target of the speed of the ship to follow, for every unit time, according to the speed setting, to change the target speed based on a given rate of change. The change rate adjusting module 64 decreases the rate of change by adjusting the rate of change at multiple stages, when the target speed set by the target speed setting module 63 approaches the speed setting.

A method of controlling a propulsion system on a marine vessel includes receiving proximity measurements describing locations of one or more objects with respect to the marine vessel, receiving a command vector instructing magnitude and direction for propulsion of the marine vessel with respect to a point of navigation for the marine vessel, and then determining a funnel boundary based on the command vector. When an object is determined to be within the funnel boundary, a propulsion adjustment command is calculated to move the marine vessel such that the object is no longer in the funnel boundary. At least one propulsion device is then controlled based on the propulsion adjustment command.

Techniques are disclosed for systems and methods for navigational danger identification and feedback. A navigation system may include one or more navigation sensors coupled to and/or associated with a mobile structure and a logic device. The one or more navigation sensors are configured to provide navigational data associated with the mobile structure. The logic device is configured to receive navigational data from the one or more navigation sensors; determine a virtual model comprising at least one navigational hazard based, at least in part, on the received navigational data; and generate a navigation display view comprising a virtual model view based, at least in part, on the determined virtual model, wherein the virtual model view comprises at least one navigation threat indicator corresponding to the at least one navigational hazard.

A control device for controlling a watercraft includes: a position detection module configured to detect a current position of the watercraft; a positioning module configured to determine a new position for the watercraft within a delimited region depending on at least one positioning parameter when the watercraft approaches a boundary of the delimited region to within a predetermined distance or a parameterizable distance.

A track management device for a movable body includes processing circuitry configured to detect a position of the movable body and determine geographic information of a region surrounding the movable body for displaying on a display, and a memory configured to store track information of the movable body, the track information including a path traversed by the movable body towards a predetermined position, and assign a priority tag to the track information associated with a current path of the movable body, when the movable body is located within a predetermined distance from a predetermined position. The processing circuitry is further configured to generate display information for displaying the track information corresponding to the geographic information on the display.

Techniques are disclosed for systems and methods to provide visually correlated radar imagery for mobile structures. A visually correlated radar imagery system includes a radar system, an imaging device, and a logic device configured to communicate with the radar system and imaging device. The radar system is adapted to be mounted to a mobile structure, and the imaging device may include an imager position and/or orientation sensor (IPOS). The logic device is configured to determine a horizontal field of view (FOV) of image data captured by the imaging device and to render radar data that is visually or spatially correlated to the image data based, at least in part, on the determined horizontal FOV. Subsequent user input and/or the sonar data may be used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.

A boat includes a dash positioned proximate a windshield at a first non-zero angle. A speaker is mounted under a top surface of the dash at a second non-zero angle. The speaker is positioned to direct sound emanating from the speaker through an opening in the dash and the windshield is configured to reflect the sound emanating from the speaker as reflected sound in an aft direction. The boat may also include an enclosure having a reflective surface positioned within a cavity formed between the deck and hull of the boat. A speaker, mounted within the enclosure, and the reflective surface are configured to reflect sound emanating from the speaker off of the reflective surface and through an opening of the enclosure.
