Abstract: The present invention relates to a fabric sail (1) which maintains a minimal surface. An elastic boundary is attached to the edges of an elastic membrane, and the edges (4) are shaped so that the membrane of the sail maintains a minimal surface configuration despite being deformed by the boundary. The sail therefore distributes strain across the sail surface and is thus free of wrinkles and creases. Points on the elastic membrane itself can be displaced but still form a minimal surface as defined by the boundary and the displaced surface connection points. In addition, strain matching allows the boundary and the elastic membrane to optimally share the strain caused by any deformation.

Abstract: A safety system, which stops the motion of a sail boat when a person falls off the boat, is comprised of a wireless transmitter carried by the person, a receiver-controller, an actuator, and a separable member which ordinarily holds a sail or a sail assembly in its working position. When the person falls off the boat and or the boat moves away, the diminution in wireless signal causes the actuator to separate the connecting member which holds sail in place, thus reducing the propulsive power and altering the motion of the boat. A preferred actuator stores manually input energy, to enable the use of a compact and low power solenoid type coil.

Abstract: A power or manually operated winch mechanism for handling the running rigging lines of a sailing yacht. The winch includes a winding drum, operating in conjunction with a level wind mechanism, which winds and stores the line during line retrieving operations and controllably releases the line when desired. Novel level wind features enable the lines to be appropriately tensioned during retrieval, to assure proper windup of the line in organized coils on the drum. During line release, the line is placed under tension by the level wind mechanism and thus positively drawn from the unwinding winch drum even when the line is not under load from the sail to which it is attached. The arrangement enables lines to be automatically released from one winch and retrieved on a second which, under a common control, as when tacking or resetting the sails of a yacht, all without the necessity of any physical line handling by crew members, resulting in a significant improvement in the safety and convenience of the crew.

Abstract: An elevated sailing apparatus that extracts traction power from the wind. It operates without the heeling moment (typical of conventional sailboats), which constrains the design and limits the power that can be used. A wing or sail is attached beneath a streamlined blimp with aerodynamic stabilizers that keep both the blimp and the wing (or sail) directed into the wind. The blimp is directed into the wind for minimum drag. The wing (or sail) is directed into the wind for a desired angle of attack. The apparatus is tilted so that a combination of dynamic lift and lateral propulsive force is generated in addition to the static lift generated by the blimp. A single tether transfers these aerodynamic forces to a boat or other vehicle. Conventional electronically operated automatic and remote control systems can be used to adjust the tilt and to tack the apparatus.
