Abstract: A wind paddle sail assembly includes a sail having stiffened upper and lower ends and a paddle or pole having an upper fixed end and a lower portion with a lower free end. A fastener fastens the upper fixed end of the paddle or pole to the upper end of the sail. A downhaul strap fastens the lower end of the sail to the lower portion of the paddle or pole for adjusting tension in the sail. A method for operating a wind paddle sail assembly is also provided.

Abstract: A shaft mount sail device that may have a sail made of a lightweight, flexible material that is capable of being tightly wound about the shaft of a paddle, push-pole or other shaft, a mechanism for attaching the sail to the shaft, and a clamping member coupled to the sail and configured to releasably clamp onto the shaft. The sail may be rolled tightly about the shaft and the clamping member fit over the shaft to secure the sail in the stowed position. The clamping member in the stowed position may serve as the handle by which a user grasps and operates the shaft. Various embodiments are disclosed.

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.

Abstract: A hand held, light weight, multi-purpose, extendable and collapsible omni-wind sail assembly for providing wind propulsion for vehicles such as kayaks, surfboards, small boats, iceboats, land vehicles, and the like. The assembly includes a flexible wind responsive sail surface having a transparent portion for user viewing therethrough, the sail surface attached at each side to masts having an attachable handle for manual maneuverability of the sail. The assembly may be stretched tautly, collapsed, tipped vertically, rotated horizontally, or all in combination simultaneously as the wind conditions may warrant, the masts having length extension means for varying the height of the sail.

Abstract: A sailing device suitable for a pleasure boat or the like of narrow width which is small in restoring force against traverse tilt. The sailing device is characterized by comprising a sail portion A composed of a backbone, a pair of left and right spars 3a, 3b extending obliquely backward from the fore end of the backbone 1, and a sail-cloth 8 attached at the fore edge thereof to the pair of left and right spars and at the aft end thereof to the aft end of the backbone 1, and a strut 4 extending downward from the fore end of the backbone 1. The lower end of the strut is directly mounted on the boat hull for rise and fall or indirectly attached to the boat hull by support of a user.

Abstract: The present invention discloses a seat board for board kiting that is made of a substantially high durability of material, having a seating recess thereon, thereby permitting a rider to enjoy the board kiting in a convenient way. The seat board for board kiting that has a seating recess formed at an upper central portion thereof, is in a shape of a generally small boat and has a kite fixed thereto to thereby obtain a propelling force, the seat board including: a body made of a polystyrene foam material; a resin layer made of fiber glass and formed on the external surface of the body for preventing the damage caused upon collision of the body against an external object; and kite fixing means provided slidably in the seating recess for fixing the kite.

Abstract: The HALF-SHUTE is directed as an accessory to propel skateboards with the power of the wind. It can easily be carried around the waist of the user when not in use. It includes a one-dimensional diamond piece of fabric. It's diamond shape bellows out in the center to capture more wind. The Edges are reinforced with double layer, folded over, material. The outer perimeter is re-enforced with heavy duty stitching. At each of the lateral ends there are attachments for the user's wrists. The inferior point of the Shute attaches to a flexible cord, which in turn attaches to an eyebolt, which is secure on the skateboard.

Abstract: A sail assembly includes a sail, a mast, a coupler, and a fastener. The mast is attached to a first side of the sail. The coupler is attached to the mast and is used to couple the mast to a handle portion of a paddle. The fastener is attached to the sail at a location opposite the first side of the sail and is used to fasten the sail to the blade portion of the paddle. The sail is held in an open position when the mast is coupled to the handle portion of the paddle at a right angle to the paddle and the sail is fastened to the blade portion of the paddle. Thus, when the mast is supported upright and the end of the sail is connected to the paddle, the sail is open and usable to propel the boat under power of the wind.

Abstract: A mastless sail for use in a two-seat kayak is disclosed. The apparatus is designed with a boomstick feature for supporting and controlling the bottom of the sail. The existing kayak paddles support and control the top of the sail. The apparatus is also designed for fast assembly and disassembly. No alterations to the kayak are necessary.

Abstract: A carrying strap for transporting the leading edge inflatable traction kite from a vehicle to the edge of the water as well as to and from the location to which the leading inflatable traction kite will be used is disclosed. A hands-free device and method for tethering a leading edge inflatable traction kite includes a quick release catch for attaching an end of a leash to a user while a second end of the leash is attached to the kite.

Abstract: A kite sailboard system for a person includes a sitting board having an upper surface, a lower surface, and a cavity. The cavity has an opening on the upper surface where the person sits. The cavity has a sitting surface for the person to sit upon, located at the bottom of the cavity. A kite provides a motive impulse force to the person and the sitting board. There are one or more tether lines attached to the kite.

Abstract: A spoon shaped simple skin kite for kite sailing having a long flexible fiberglass rod on the leading edge as the only structure, many bridles that are all connected directly to that rod, no lines a 30 inches long straight handle to steer it that turns around the same axis as the kite turns.

Abstract: What is disclosed is a supporting frame for a hand-supported sailing rig in which a mast with a middle section curved in a preferably circular arc-shaped manner and merging into two end portions is formed, the radii of curvature of said end portions being smaller than the one of the middle section. The supporting frame has supporting means for supporting the rig at the body of the user. The middle section is preferably provided with a joint device which allows the arrangement of the supporting components in the folded state in a parallel orientation towards each other.
