A kite driven watercraft power generating system which includes at least one operative location defined on the watercraft, at least one inoperative location defined on the watercraft, a plurality of kite base stations mounted displaceably about the watercraft and, an orientation subsystem for displacing each of the plurality of kite base stations between the at least one operative, and, the at least one inoperative locations, respectively, wherein each of the plurality of kite base stations is further configured to orientate its respective kite in a wind harvesting and energy generating mode when located in the at least one operative location, and, in a kite retraction mode, when located in the at least one inoperative location.

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.

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 power kite and a bridle system is adapted to connect the power kite to a control box. The power kite includes a leading edge and a trailing edge, and the bridle system includes multiple power lines and at least two steering lines. The steering lines are connected to zones including wingtips of the power kite such that a steering angle of the power kite is controllable by balancing the steering lines. The multiple power lines comprise a front line connected to a front zone of the power kite including a central part of the leading edge and comprise a back line connected to a back zone of the power kite including a central part of the trailing edge, such that an angle of attack of the power kite is controllable by balancing the front and back lines.

A control device for controlling a kite steering arrangement, including a base, a control bar support extending downward on the base, a control bar pivot point mounted displaceably about the control bar support, a pair of interconnecting members extending between opposing end regions of the control bar and the base upper the control bar support, a tensioning mechanism, a base pivot point, a base rotator for allowing rotation of the base about a vertical axis thereof, a manipulator that manipulates the base pivot point and base rotator, and a communicator, that communicates adjustment of the interconnecting members to the kite steering arrangement. The length aspect of the interconnecting members is adjusted by pivoting the control bar about the control bar pivot point and/or by displacement of the control bar pivot point relative the control bar support.
