Abstract: An improved inflatable wing and kit including an inflatable airframe, a center strut connectable to the airframe, a wing panel connectable to the airframe and to the center strut, and a handle. The handle may have first and second ends, each configured to removably connect to the center strut via connection devices on the center strut which are configured to receive the first and second ends of the handle.

Abstract: A valve assembly for mounting on a substrate via rotational engagement with a base of the valve assembly, and a cap for such a valve assembly. A body of the cap is rotatably engageable with the base between opposing first and second terminal ends. At each of the first and second terminal ends, the body and the base abut each other to prevent rotation between the body and the base. As a result, torque applied to the cap is transmitted to the base to vary rotational engagement of the base with the substrate. A slot formed in the cap may be suitable to receive a protrusion on the base and may fork into two separate portions that terminate in opposing terminal ends to allow selective engagement of the protrusion with the two portions. The protrusion abuts against the terminal ends to transmit torque from the cap to the base.

Abstract: 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.
