ABSTRACT:
An elongate board which produces increased lift when moved through a fluid such as air or water. The elongate board includes a main body with an opening in its central region. A plurality of transverse wing sections are mounted in tandem in the central opening along the longitudinal axis of the main body. Between each wing section is an open slot allowing the fluid to flow over the wing sections, creating a lifting force on the elongate board. The elongate board may be utilized in many different sports requiring the use of a ski or board, such as water skiing, snow skiing, surfboarding, snow boarding, and sky surfboarding.
