A method for aligning steering angles of marine propulsion devices. The method includes receiving a first steering request to steer the marine propulsion devices, where when the first steering request is received, steering for a first device is deactivated and steering for a second device is activated, and changing a steering angle of the second device according to the first steering request while leaving a steering angle of the first device unchanged. The method includes receiving a request to activate steering for the first device and receiving a second steering request, then changing the steering angles of both the first and second devices when the second steering request is received after receiving the request to activate steering, and changing the steering angle of the second device while leaving the steering angle for the first device unchanged when the second steering request is received before receiving the request to activate steering.

The miniature rudder is pivotably mounted on the rigid conduit relative the aft facing outlet whereby combustion gases exhaust past the rudder. The rudder control system has a user interface inside the boat and has a control mechanism pivoting the rudder in response to inputs to the user interface.

A method for maintaining a marine vessel propelled by a marine propulsion device in a selected position includes determining a current global position of the marine vessel and receiving a signal command to maintain the current global position. The current global position is stored as a target global position in response to receiving the signal command. A subsequent global position of the marine vessel is determined and a position error difference between the subsequent global position and the target global position is determined. The method includes determining marine vessel movements required to minimize the position error difference, and causing the marine propulsion device to produce a thrust having a magnitude, a direction, and an angle calculated to result in achievement of the required marine vessel movements. At least one of timing and frequency of discontinuity of thrust production is controlled while the position error difference is minimized.

A marine vessel maneuvering system includes a propulsion device, a steering device, a forward/reverse drive switch, a steering wheel, a forward drive operator, a reverse drive operator, and a controller. The forward drive operator and the reverse drive operator are respectively located on one and the other sides of a pivot axis of the steering wheel, and are pivotable together with the steering wheel. The controller performs a forward drive propulsion control and a reverse drive propulsion control to set the propulsive force direction and control a magnitude of the propulsive force according to the operation of the forward drive operator and the reverse drive operator. The controller enables the forward drive propulsion control in a forward drive operation valid range. The controller enables the reverse drive propulsion control in a reverse drive operation valid range.

A steering system for a marine vessel includes a cable translatable in response to a steering input command. The steering system also includes a rudder pivotable to steer the marine vessel. The steering system further includes a link member operatively coupled to the rudder. The steering system yet further includes a sensor positioned to detect a load associated with the cable in response to the steering input command. The steering system also includes an electric power steering system in operative communication with the sensor to receive a signal from the sensor and provide a powered assist to the link member.

A control handle for controlling an electric drive system of a sailboat is provided. The control handle comprises a handle and a handle shaft, where the control handle is provided with a plurality of engagement positions. A first engagement position is adapted to engage a forward drive mode of the electric drive system, a second engagement position is adapted to engage a reverse drive mode of the electric drive system, a third engagement position is adapted to engage an idle drive mode of the electric drive system, and a fourth engagement position is adapted to engage a hydro energy generation mode of the electric drive system.

An adjustable boat console movable between an operating position and a stowed position. The adjustable boat console comprises a housing comprising a back panel that will be positioned flush with a deck of a boat when the adjustable boat console is in the stowed position. The adjustable boat console further comprises a pivotal connecting component connecting the housing to the deck of the boat at a forward edge. The adjustable boat console further comprises an adjusting component. The adjusting component is configured to raise and retract the housing from the deck. A system for adjusting a boat console between an operating position and a stowed position is also disclosed.

A propulsion system on a marine vessel includes at least one steerable propulsion device and at least one lateral thruster. A steering wheel is operable by a user to steer the at least one propulsion device. A user interface device is operable by a user to provide at least a lateral thrust command to command lateral movement and a rotational thrust command to command rotational movement of the vessel. A controller is configured to determine a difference between a steering position of the propulsion device and a centered steering position. A user interface display is controllable to indicate at least one of the steering position of the propulsion device and the difference between the steering position and the centered steering position. The controller is further configured to determine that the steering position is within a threshold range of the centered steering position prior to enabling a joystick thrust control mode.

A steering apparatus for a marine vessel includes a central portion supported rotatably around a rotation fulcrum with respect to a hull, a wheel portion, a spoke portion that connects the central portion and the wheel portion, first switches, second switches near the first switches, and paddles operable to cause a thrust to be applied in a front-rear direction to the hull. The first and second switches control the hull in different modes. The first switches are located at positions where a marine vessel operator is able to operate the first switches with the fingers of hands operating the paddles. The first and second switches are on the spoke portion and have different heights in a pressing direction.
