A system for guiding a first watercraft remotely has a rudder proximate the stern of the first watercraft, having a rudder shaft extending upward from a deck area at the stern, a servo device having an output servo horn coupled to the rudder shaft by a linkage, adapted to turn the rudder shaft in concert with the servo horn, a radio receiver/controller adapted for receiving radio signals for guiding the first watercraft, the radio receiver/controller coupled to the servo device, and a radio transmitter having an input wheel for providing steering commands. The system is characterized in that the input wheel of the radio transmitter is manipulated by a user remote from the watercraft, the radio signals for guiding the first watercraft are transmitted from the radio transmitter to the radio receiver/controller on the first watercraft, and the radio receiver/controller provides operating signals to the servo device to rotate the servo horn either clockwise or counterclockwise, guiding the first watercraft.

Various aspects provide for a propulsion system (200) for a ship (100) comprising at least first and second thrusters (205, 206) and first and second directors (220, 720), wherein a computing platform (300) is coupled to the thrusters and directors being configured to receive desired longitudinal and lateral headings (750, 760) and determine a configuration of the propulsion system that is expected to propel the ship in the desired longitudinal and lateral headings.

A boat stabilizer having an upper harness for attachment to a vessel, the upper harness having an assembly control system for controlling attached wing assemblies, each wing assembly having a wing attached to the assembly control system and a wing mount attached to the wing and the assembly control system. The boat stabilizer may be further comprised of a controllable parasail comprising a parasail canopy, a plurality of parasail cords attached the parasail canopy, a parasail mount attached to the upper harness and the parasail cords, a parasail control rudder attached to each parasail cords, and yaw and pitch controllers, both of which are attached to the parasail control rudder. The assembly control system is configured to work in conjunction with the controllable parasail to provide the desired balance of vertical lift and forward propulsion to the attached vessel, while also providing directional control to the attached vessel.

Techniques are disclosed for systems and methods to provide dynamic display systems for mobile structures. A dynamic marine display system includes a user interface comprising a primary display and secondary display, where the secondary display is disposed along and physically separate from an edge of the primary display, and where the secondary display comprises a touch screen display configured to render pixelated display views and receive user input as one or more user touches and/or gestures applied to a display surface of the secondary display. A logic device is configured to receive user selection of an operational mode associated with the user interface and/or the mobile structure and render a primary display view via the primary display and/or a secondary display view via the secondary display corresponding to the received user selection and/or operational mode.

Embodiments described herein relate generally to a sailing vessel that can substantially obviate the heeling problem experienced by classical sailboats. During navigation, the sailing vessel is driven forward by an aerodynamic force exerted by wind on the sail, and balanced by a hydrodynamic force exerted by water on a float on the stern of the sailing vessel, the aerodynamic force and the hydrodynamic force being parallel or substantially parallel to a longitudinal axis of the sailing vessel.

A marine autopilot system is disclosed. While in autopilot mode, the marine vessel's autopilot system autonomously steers the marine vessel's rudder. Steering input provided using the helm typically results in counter-steering to the autopilot. If the autopilot is following a current heading or course (route), the autopilot may continue its efforts to remain on the heading or course in response to the deviation caused by steering input to the helm. The disclosed autopilot system improves this problem by including one or more sensors that measure helm movement and wirelessly transmit helm movement data to one or more components of the marine vessel's electronic network. If the operator of the marine vessel manually steers the helm to deviate from a current heading or course, helm movement exceeding a predetermined autopilot disengagement threshold may cause the autopilot control to temporarily disengage, allowing a user to manually steer the marine vessel.
