ABSTRACT:
A vehicle for travel on snow or water consisting of an elongated main member having a top and a bottom surface with a venturi effect. First and second runners extend lengthwise and downwardly along opposed edges of the bottom surface from a point spaced rearwardly of the front end of the member to a point spaced forwardly of the rear end of the member. The runners and bottom surface define the venturi section that tapers inwardly to a narrow throat in the vicinity of the middle of the member and then tapers outwardly. Elongated side cuts are provided to the elongated outside surfaces of the board, the side cuts creating a surface which is narrower in width between the front and the back of the surface.
