A gliding board with an effective edge length to waist width ratio of 3.8 to about 4.35, a waist width of at least about 250 mm, a core that has an approximately constant thickness of greater than 5 mm along substantially the entire running length of the board and to within about 80-100 mm of the effective edge points, but thins to a thickness of about 2 mm or less in areas nearer the effective edge points, and/or side edges that include a curved, concave sidecut portion at the waist, curved, convex transition zones at the forward and rear effective edge points and a straight section in the running length adjacent each transition zone.
