  • Publication number: 20120247379
    Abstract: A removable sail for a paddle-style boat, such as a kayak preferably takes the form of a fast deploying down-wind sail attachable to a deck of the kayak. The sail includes a curved, but non-circular shaped flexible material coupled to a collapsible, continuous frame member, for example the frame member may be sewn into a channel made by the material. When mounted to the deck of the boat, the sail may be arranged in a deployed or a stowed configuration, the latter being deployable on the fly in that the sail can be quickly sprung into the deployable configuration. The non-circular shape of the sail cooperates with a hull shape of the boat while providing a sufficient surface area for capturing wind energy. The sail may also include a transparent region that helps prevent excessive amounts of spray from striking the paddler and yet still provides an adequate viewing range.

  • Patent number: 8135504
    Abstract: A method is disclosed that resolves a long-standing seafaring problem of how close to the wind to sail. Sailboats need a convenient way to determine the optimal heading to minimize the Tacking Time to Destination (TTD). Unlike Velocity Made Good (VMG), the method disclosed here allows route planning before the trip, predicts travel time on different points of sail, allows comparison of the optimal tacking routes, and also plots the different routes so that it is inherently obvious that a particular tacking angle is longer and more off-course but will arrive sooner because of the speed on that heading. These principles can be implemented with manual dials that define the distance and speed, to calculate the relative or actual travel time on a leg without using electronics. Software is also described that visually illustrates the current and optimal headings by calculating Tacking Time to Destination before departure.

  • Patent number: 7752987
    Abstract: A sail assembly having a single, closed-loop support batten that supports a flexible sail. The sail is a hollow body defining a substantially hemispherical shape when fully expanded by captured wind. The support batten is housed in a perimeter sleeve at the front end of the sail. The support batten is stiff enough to support the sail, yet elastic enough that it can be twisted and coiled as three contiguous coils for compact folding. The sail has a significantly smaller size in the folded and coiled orientation, and is capable of rapid self deployment due to the energy stored in the folded batten. The deployed sail can be fastened to the deck of a small watercraft, hand held, or fastened to the blade end of a paddle or oar for capturing the energy in the wind to propel a small watercraft.

  • Patent number: 7568442
    Abstract: A sailboat is disclosed wherein the sailboat includes a three degree-of-freedom pivot assembly, sail-mounted ballast, and sail control system. These three features increase sailing efficiency and reduce both hydrodynamic and aerodynamic drag on the sailboat. This sailboat incorporates a rigid sail with sail-mounted ballast to balance the rolling moment and pitching moment produced on the sail by the wind. The rigid self-supported sail increases sailing efficiency by eliminating the need for supporting wires and structures and by taking advantage of the superior aerodynamic characteristics of rigid sails over flexible sails. Finally, the sail control system controls the sail's orientation by rotating the components of the three degree-of-freedom pivot assembly to maximize the sail's aerodynamic efficiency.

  • Patent number: 7263939
    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.

  • Patent number: 6923131
    Abstract: A windsurfing catamaran with a self-stabilizing wing. The wing is moved to the correct position by counter balancing water pressure from a rotating central keel connected to a central mast. The keel rotates in the opposite direction of the wing when the wing is moved off center by wind. The keel rotates such that a greater surface area is presented to water flow striking the keel. Water pressure on the keel offsets wind pressure on the sails and returns the keel and mast back to an upright position. This increases stability, lift, driving force, and speed. A central catamaran platform provides hinged struts and shock absorbers between the rear end of the central platform and planing hulls to reduce impact damage. The hinged struts and shock absorbers reduce water drag and the braking effect of repeated hull impacts with water resulting in a further increase in speed.
