Abstract
A modified snowboard (10) having transverse channels (28) formed in a convex bottom (14) to facilitate movement through the snow. The sides (46) and (48) project beyond the bottom (38) of a snowboard (36) to form longitudinal grooves (54) with downwardly extending edges (56) to increase maneuverability and stability of the snowboard both at slow and high speeds. Upwardly projecting flanges (74) extend the length of the sides (64) and (66) of a snowboard (62) to prevent snow from moving over the top (72).
