A boat includes a controller that is communicatively coupled to a control screen. The controller has stored therein a plurality of modes corresponding to an activity and includes a plurality of controls corresponding to the activity. The controller is configured to display on the control screen, when one of the modes is activated, the plurality of controls for the activated mode. The activated mode may also be an operating mode that corresponds to an operational condition of the boat. The boat may include a processor that is configured to generate an adjusted audio signal by selecting one or more of a plurality of subranges of frequencies of an audio signal and adjusting the selected subranges to compensate for at least one environmental condition associated with the operational condition of the boat corresponding to the operating mode.

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.

a drilling or work-over vessel (10) is disclosed comprising a number of operational equipment (300), wherein the drilling or work-over vessel comprises at least one operational control and/or state unit (100) comprising at least one processing unit (102), wherein the at least one operational control and/or state unit (100) comprises or are in connection with a memory and/or storage (103), and at least one sensor unit (200), wherein the at least one sensor unit (200) is adapted to obtain one or more measured physical values and to provide data representing the one or more measured physical values and/or derived values thereof to the at least one operational control and/or state unit (100), the memory and/or storage (103) comprises a data representation of a computational physics model of at least a part of the drilling or work-over rig, and the at least one processing unit (102) is adapted to derive data representing an estimation of one or more physical states (such as defined by limits of forces, relative motion between operational equipment and vessel, or between other two pieces of operational equipment) estimated to act on at least one operational equipment (300) in response to the data representing the one or more measured physical values and/or derived values thereof as provided by the at least one sensor unit (200).

A craft includes a hull, a wing, a hydrofoil, and a control system. The wing is configured to generate upwards aero lift as air flows past the wing to facilitate wing-borne flight of the craft. The hydrofoil is configured to generate upwards hydrofoil lift during a first mode of operation as water flows past the hydrofoil to facilitate hydrofoil-borne movement of the craft through the water. While the craft is hydrofoil-borne, the control system is configured to determine the upwards aero lift generated by the wing. The control system is further configured to control the hydrofoil to generate downwards hydrofoil lift to counteract the upwards aero lift generated by the wing that maintains the hydrofoil at least partially submerged in the water while the determined upwards aero lift is below a threshold lift.

A system for operating a boat equipped with an electric drive includes a component controller. The component controller includes a component interface for connecting a system component of the electric drive, and a communication interface for connecting the component controller to a system bus of the drive control.

Disclosed is a method of decreasing pressure fluctuation induced on a surface of a hull due to propeller cavitation by adjusting a relative rotation angle of propellers of a twin-propeller ship.

Methods and apparatus for active watercraft monitoring. A system includes cameras positioned on a watercraft to capture real time images of regions directly forward, rearward and laterally of the watercraft, and an active watercraft monitoring process residing in a computing device positioned in the watercraft, the active watercraft monitoring process receiving real time video images from the cameras, processing the real time video images and generating a simulated image of the vessel in relationship to its surroundings in conjunction with the processed real time video images

A method comprising, by at least one processing unit, obtaining data collected by one or more sensors of at least one marine vessel, said data being representative of one or more situations encountered by the marine vessel during its voyage, prioritizing data according to at least one relevance criterion, wherein when the marine vessel is located in a zone in which at least one remote data communication link meets a criterion, transmitting at least some of the data using the at least one remote data communication link, wherein data are transmitted according to priority determined for the data, thereby facilitating transmission of relevant data for the purpose of training one or more machine learning algorithms (e.g. deep learning algorithms) providing output based on these data.
