A steering device for an outboard motor is rotatably supported on a hull of a boat about a steering axis. The steering device includes a tiller handle, an actuator, and a linkage. The tiller handle is attached to the outboard motor. The actuator rotates the tiller handle about the steering axis. The link linkage is movably disposed between a connection position and a blocking position. The linkage transmits the driving force from the actuator to the tiller handle at the connection position. The linkage shuts off the transmission of the driving force from the actuator to the tiller handle at the blocking position.

A steering system for a boat, a marine vessel or the like, having an outboard motor with an underwater propeller and a removable fastening terminal at the hull, includes a steering control member, such as a steering wheel, a rudder bar or a rudder wheel, and an actuator that changes the orientation of the propeller by changing the angular position of the rotation axis thereof relative to the longitudinal axis of the boat. An intermediate framework, positioned between the stationary part of the boat and the fastening terminal of the engine, includes a housing for at least a portion of the drive assembly and/or of the actuator fastened to the intermediate framework.

A helm for controlling a marine vessel with instruments and a steering device. The marine vessel has forward and aft ends defining a longitudinal center line therebetween. The helm includes a base that extends upwardly from a floor of the marine vessel to a top of the base. The base supports the steering device. A cover is pivotally coupled to the top of the base, where the cover is pivotable away from the longitudinal center line between an open position and a closed position. Wiring for the instruments is accessible from the top of the base only when the cover is in the open position.

A system for controlling a ship 1 comprises a ship 1 having: a ship control unit 204 configured to determine situation information of the ship 1; and a transmitter-receiver 12 connected to the ship control unit 204 and configured to transmit the situation information. A remote control centre 18 remote from the ship 1 comprises a transmitter-receiver 16 configured to receive situation information of the ship 1; and a remote control unit 202 configured to determine pilot-control information for maneuvering the ship 1 based on the situation information and configured to transmit the pilot-control information to the ship 1 via the transmitter-receiver 16 of the remote control centre 18. The ship control unit 204 or the remote control unit 202 is configured to determine a quality of a connection between the transmitter-receiver 12 of the ship 1 and the transmitter-receiver 16 of the remote control centre 18.

A method for controlling a course of a marine vessel powered by a marine engine as it moves in a body of water includes determining a current global position and a current heading of the vessel and initiating an auto-waypoint mode of a vessel course control system. In response to initiation of the auto-waypoint mode, the method includes setting a course for the vessel based on a current position of a steering wheel of the system and the vessel's current global position. The method thereafter includes automatically rotating a steerable component coupled to the vessel and rotatable to affect a direction of movement of the vessel so as to counteract external forces on the vessel and thereby to maintain the vessel's set course.

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.

This disclosure describes a configuration of an unmanned aerial vehicle (UAV) that will facilitate extended flight duration. The UAV may have any number of lifting motors. For example, the UAV may include four lifting motors (also known as a quad-copter), eight lifting motors (also known as an octo-copter), etc. Likewise, to improve the efficiency of horizontal flight, the UAV also includes a pivot assembly that may rotate about an axis from a lifting position to a thrusting position. The pivot assembly may include two or more offset motors that generate a differential force that will cause the pivot assembly to rotate between the lifting position and the thrusting position without the need for any additional motors or gears.
