Disclosed is a kite or wing with a canopy made of a film material which cannot be folded without being creased but having one or more strips of flexible material running across the canopy, wherein the flexible material can be folded without creasing, The kite or wing can be folded along the flexible material strips and then rolled up from the canopy ends for storage or transport.

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.

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 method of loading a bladder into an outer envelope of an inflatable kite involves inserting the bladder through a valve opening in a portion of the outer envelope of the inflatable kite until a valve of the bladder is positioned in the valve opening. The preferred manner of inserting the bladder into position is accomplished by securing a line to a remote end of the bladder and using the line to draw the bladder through the valve opening.
