Approximately vertical side walls are equally curved inwardly to form a waistlike narrow portion in the elongated body. A substantially flat bottom contact surface curves convexly downward to form a fulcrum at the low point. The fulcrum aligns with the centerlines of both side curves. A major portion of each side curve intersects a major portion of the bottom fulcrum curve to form a curved turning edge, which contacts the snow for its entire length when the snow board is tilted back over the fulcrum and to one side for steering. Protruding above a top flat ride-on surface are a rear foot stop and a double front foot stop for wedging the foot therebetween. Pivotally secured to an axle through the front foot stop a U-shaped handle pivots up for a stand-up balance and steering hand lever and down below the ride-on surface for storage, for a sit-down hand grip or for no-handle stand-up riding. Additional side grips, handle hold-down and safety release binding are optional.

A highly maneuverable rigid snow board comprising an elongated body, of substantially greater depth in midsection that at each end and substantially flat on the top surface, substantially vertical longitudinal side surfaces provided with equal opposing inwardly concave curves in the side surfaces forming a “waistlike”narrowed portion between wider front and rear sections in plan view, and a substantially arched bottom comprising a longitudinal downwardly convex curve forming a fulcrum point separating a substantially flat bottom sliding contact area from a smaller upturned rear backshift area, and further comprising, at a front end a small upturned tip portion, wherein the centerlines of both side concave curves and the centerline of the bottom fulcrum with each side curve forms a long continuous curved bottom turning edge, the major central portion of which curved bottom turning edge rests flush with a flat snow surface to steer the snow board approximately in the direction of edge curvature when the snow board is pivoted onto the fulcrum and tilted to either side onto the curved bottom edge.
