Disclosed is a hand held wing rig a center strut of which has recessed grips.

Disclosed is a hand-held wing rig for wind-powered sports, which is provided with a stiffening element for stiffening the front tube.

Woven UHMWPE fabric stretches in the bias direction to such an extent that it is unsuitable for many potential applications and is porous, allowing air and water transmission. A composite UHMWPE material includes a single ply of high tenacity woven UHMWPE fabric having warp fibers in a first direction and weft fibers in a second direction orthogonal to the first direction. The UHMWPE fabric has first face and a second face. A stretch resisting axially oriented fusion layer is fused to at least one of the first face or the second face of the UHMWPE fabric with an axis aligned parallel to at least one of the UHMWPE fabric warp and weft axes, such that the stretch resisting fusion layer increases fabric tensile strength and inhibits bias stretch of the UHMWPE fabric, and renders the UHMWPE woven fabric air and water impermeable.

A wingsurfing wing, a handle thereof and a method of retaining the handle. The handle includes a member that is elongated in an elongation direction to be suitable for grasping. First and second attachment portions suitable for attaching the member to a strut of the wing extend from the member and are spaced apart from each other in the elongation direction. A fitting defines the second attachment portion and is adjustable between first and second configurations. In the first configuration, the fitting is movably engaged with the member to reposition the second attachment portion in the elongation direction. In the second configuration, the fitting is fixedly engaged with the member. The method includes causing frictional engagement between the strut and the fitting via an interference fit between a fastening portion and the strut, and causing frictional engagement between the fitting and the member to prevent movement of the fitting.

A training device having a platform for receiving at least one person; at least one anchoring point for fastening a securing means that secures the person on the training device; a vertical rotation axis Z, about which the training device can be mounted rotatably or is mounted rotatably. The anchoring point is arranged at or above the height of the buttocks region of the person, and the training device is rotatable about this rotary axis Z by means of forces acting on the platform.

Devices, such as aerodynamic kites used in kiteboarding (also known as kitesurfing), handheld aerodynamic wings used in wing foiling and wing surfing, and paddles used in paddleboarding, for generating a force for powering a user on an appropriately configured vehicle, such as a kiteboard, kitesurfing foilboard, hydrofoil board, surfboard, wing board, wing foil board, stand up paddleboard, stand up paddleboard with hydrofoil, roller skates, rollerblades, skateboards, snowboards, skis, or ice skates, to traverse across a body of water, sand, earth, paved area, snow, or ice, are provided with a thrust generating device (e.g., an electric ducted fan system) to assist in generating said force.

A hand-held wing is configured to include an inflatable leading edge from which a substantially rigid boom extends which is configured to be held by the user to guide the wing, with the leading edge being configured to extend about V-shaped or U-shaped upwards (away from the surfer) in the direction of approach.
