A method of making a snowboard or ski so that the bottom surface of the snowboard or ski is capable of bowing into a desired longitudinal curvature, with a circular arc being the preferred shape, in order to enable a "perfect" turn to be carved. The method comprises the steps of selecting a desired longitudinal curvature of the snowboard during turns, determining the desired curvature of the snowboard at a plurality of cross-sectional portions thereof in order to achieve the desired curvature, and selecting the cross-sectional area moments of inertia at each of the plurality of cross-sections to provide the desired curvature. The thickness of the core of the snowboard is the preferred design variable. The center section of a snowboard designed in accordance with this method has smaller average area moment of inertia than one or both of the front and rear mounting zones. Snowboards designed and constructed in accordance with this method exhibit improved turning performance, particularly in sharp, tight turns.
