A snowboard 10 designed to maintain a riding edge with an arc of constant curvature has a relatively thick base in the mounting zones 24, 28 beneath each of the rider's feet and a relatively thin base in the area 30 between the two mounting zones. Consequently, when the snowboard is being used, the portions of the snowboard coming in contact with the surface of the snow will substantially lie on segments of a circular arc, and the back half of the snowboard will substantially follow in the track of the front half of the snowboard. The curvature of the snowboard in response to the application of forces by its rider is a function of the Area Moment of Inertia of the transverse cross-sectional areas along the snowboard's length, which is in turn a function of the geometry of the transverse cross-section A-A.
