Techniques are disclosed for systems and methods to provide graphical user interfaces for assisted and/or autonomous navigation for mobile structures. A navigation assist system includes a user interface for a mobile structure comprising a display and a logic device configured to communicate with the user interface and render a docking user interface on the display. The logic device is configured to monitor control signals for a navigation control system for the mobile structure and render the docking user interface based, at least in part, on the monitored control signals. The docking user interface includes a maneuvering guide with a mobile structure perimeter indicator, an obstruction map, and a translational thrust indicator configured to indicate a translational maneuvering thrust magnitude and direction relative to an orientation of the mobile structure perimeter indicator.

Disclosed is a method for controlling a hydrofoil board powered by a motor driven propeller. The motor is controlled by a hand controller configured with user selectable operating pre-sets including a first operating pre-set, wherein the board is accelerated to a first speed which is less than that required for the board to hydrofoil, and a second operating pre-set, wherein the board is accelerated to a second speed sufficient for the board to hydrofoil. Alternatively, the operating pre-sets may limit the motor power. A system for operating a hydrofoil board is also disclosed, which includes a propulsion control unit comprising a propulsion source, and a hand controller configured to receive a first user input and a second user input and to transmit the user inputs to the propulsion control unit.

A method for controlling low-speed propulsion of a marine vessel powered by a marine propulsion system having a plurality of propulsion devices includes receiving a signal indicating a position of a manually operable input device movable to indicate desired vessel movement within three degrees of freedom, and associating the position of the manually operable input device with a desired inertial velocity of the marine vessel. A steering position command and an engine command are then determined for each of the plurality of propulsion devices based on the desired inertial velocity and the propulsion system is controlled accordingly. An actual velocity of the marine vessel is measured and a difference between the desired inertial velocity and the actual velocity is determined, where the difference is used as feedback in subsequent steering position command and engine command determinations.

The present disclosure generally relates to a joystick device (100) operable to provide speed, direction and steering commands for controlling a marine vessel (300). The present disclosure also relates to a marine propulsion control system controlling a set of propulsion units (308, 310, 312 and 314) carried by a hull of a marine vessel (300), wherein the marine propulsion control system is adapted to receive an input command from such a joystick device (100).

A modular, weight-shift controlled watercraft device is disclosed which includes: a modular board removably attachable to a power system. The power system includes a modular power supply system, and a modular propulsion system. The power supply system includes a housing including a battery. The propulsion system includes a modular strut, a modular propulsion pod, and a modular hydrofoil. In one embodiment, the power supply system is removably and mechanically attachable directly to the propulsion system.

An outboard motor steering assembly for steering a tiller outboard motor includes a control stick that is movably mounted in a boat. The control stick extends forwardly from a seat in the boat. In this way the control stick is accessible to a driver of the boat. The control stick is positionable in a left position, a right position or a center position. A plurality of pulleys is each rotatably coupled to the boat. A pair of cables is each coupled between the control stick and the outboard motor. Each of the cables urges the outboard motor to turn to the right when the control stick is positioned in the left position for steering the boat to the port side. Additionally, each of the cables urges the outboard motor to turn to the left when the control stick is positioned in the right position for steering the boat to the starboard side.

An outboard motor includes a trolling mode. The outboard motor includes an outboard motor body including a propeller and a drive source, a tiller handle body extending forward from the outboard motor body, a grip handle extending from a front end surface of the tiller handle body and configured to steer the outboard motor body via the tiller handle body, and a trolling switch attached to the tiller handle body and configured to adjust a trolling speed. An operation portion of the trolling switch is attached to a lower front end surface of the tiller handle body, the lower front end surface being located below the grip handle.

An outboard motor includes an engine, a generator to generate power by driving of the engine, a driving force transmitter to transmit a driving force from the engine, a propeller shaft to rotate by being switched from a neutral state in which a clutch is disconnected from the driving force transmitter of the engine at idle to a non-neutral state in which the clutch is connected to the driving force transmitter, and a controller configured or programmed to perform a control to reduce a rotation speed of the engine by regeneration of the generator based on a user's switching operation on a shift operator to switch the outboard motor from the neutral state to the non-neutral state, and then connect the clutch to the driving force transmitter while rotating the engine.

A foot controller system includes a foot controller having a base that engages a portion of a marine vessel when the foot controller is in an operable position. The foot controller also includes a foot pedal pivotable, with respect to the base, about a first axis, and rotatable, with respect to at least a portion of the base, about a second axis different from the first axis. The foot controller controls a first aspect of a marine motor system when the foot pedal is pivoted about the first axis and controls a second aspect of the marine motor system different from the first aspect when the foot pedal is rotated about the second axis.
