This disclosure relates generally to controlling movement of at least one steering device on a watercraft.

Lightweight vessel with a kart-like appearance of the type consisting of a lightweight vessel shell, the deadworks thereof being built with all the additions of a kart, the vessel being essentially characterized in that it consists of a shell of a light vessel (1), in the middle part of which there is a propulsion motor (2) which transmits the power to the driving means (4) via transmission means (3), the deadworks consisting of an assembly of elements that form part of the aesthetics of a competition kart, especially consisting of an aerodynamic seat (6) surrounded by aerodynamic side panels (12), an aerodynamic front panel (17), an aerodynamic rear panel, and four wheels (14) with the corresponding mudguards (15) thereof.

A steering system for a marine vessel comprises a helm, a control head, and a joystick. The helm and control head may respectively provide user inputted steering commands and user inputted shift and throttle commands on a first CAN network. The joystick and the control head may respectively provide user inputted steering commands and user inputted shift and throttle commands on a second CAN network. The helm may provide user inputted steering commands on the first CAN network. The control head may provide user inputted shift and throttle commands on the second CAN network. The joystick may provide user inputted steering commands and user inputted shift and throttle commands on either the first CAN network or the second CAN network.

A marine electric power steering system includes an actuator assembly, a gear assembly, and a cable assembly. The actuator assembly has an actuator assembly input and an actuator assembly output. The actuator assembly input is operatively connected to a steering shaft that extends along a steering column axis. The gear assembly includes a first gear that is driven by a second gear and a crank arm extending from the first gear. The cable assembly extends from an end of the crank arm to a steering device.

A system for transmitting energy and data for vessel steering wheels includes a first part mounted integral with the dashboard of the vessel and a second part mounted integral with the steering wheel, the first part including a first transmission system connected to a power source mounted onboard the vessel. The second part includes a second transmission system connected to a system for exploiting the transmitted energy and data, the first and second transmission systems being configured to transmit the electric current from the power source to the exploitation system. A system for detecting the voltage of the power source and/or the current absorbed by the exploitation system are also provided, a first control unit having a first switch configured to activate/deactivate the connection of the first transmission system to the power source, the first switch being operated on the basis of the value detected by the detection system.

A boat comprises a hull, a primary steering mechanism carried by the hull, a control station located on the hull, a helm located at the control station, and a thruster system carried by the hull. The primary steering mechanism, such as a rudder, is operable via the helm with a helm input being derived from operation of the primary steering mechanism thereby. The thruster system includes at least one thruster mounted to the hull, distinct from the primary steering mechanism, and a controller. The controller receives the helm input and is configured with program instructions to operate the at least one thruster responsive to the helm input to supplement a corresponding movement of the hull. The controller can also automatically operate the thruster responsive to direction, speed and ballast inputs.

A marine vessel control system comprises an outer port engine which has an actuator for imparting steering motion to the outer port engine and an outer starboard engine which has an actuator for imparting steering motion to the outer starboard engine. There is an inner port engine and a tie bar coupling the inner port engine to the outer port engine. There is an inner starboard engine and a tie bar coupling the inner starboard engine to the outer starboard engine. There is an input device for inputting user steering commands to the marine vessel control system in which movement of the input device actuates the said actuators to impart steering motion to the said engines.

An embodiment of a system for controlling a marine vessel includes an electrical power steering unit coupled to a mechanical control system, the mechanical control system including a steering wheel connected by a shaft to a mechanical cable assembly, the mechanical cable assembly configured to be actuated by the steering wheel to control a steering mechanism of the marine vessel. The electrical power steering unit includes an electric motor configured to apply a torque to the mechanical cable assembly. The system also includes a processor configured to control the electrical power steering unit to provide at least one of steering assist and control of the marine vessel.

An embodiment of a system for controlling a marine vessel includes a torque and/or position sensor configured to measure at least one of a torque applied by a steering wheel of the marine vessel and a rotational position of the steering wheel, and a processing device configured to receive a measurement of the steering wheel and electronically control a steering mechanism at a stern region of the marine vessel. The processing device is configured to estimate an angle of the steering wheel, determine a corresponding angle to be applied to the steering mechanism, and transmit a steering command based on the corresponding angle to an actuation device at the stern region.

A modular steering console. The modular steering console has a main console portion having a top side and a side. The top side includes holes for receiving bolts. The side of the main console portion has holes for receiving bolts. The modular steering console has one or more brackets having slots in a top side configured to be fastened to the main console top side by bolts through the slots to allow lateral adjustment of the brackets while allowing a side of the brackets and the side of the main console portion to sandwich a side of a boat.
