ABSTRACT:
An outrigger edge enhances ability to turn and maintain control of a ski or snowboard on ice or snow. The outrigger edge is provided outside and above the normal edge of a ski so it only makes contact with the snow or ice when the ski is tilted through a sufficient angle with respect to the surface of the snow or ice. The angle is preferably in the range from about 30 to about 60 degrees, more preferably around 45 degrees, to reduce or avoid contact during skiing on flat terrain but to allow contact when needed on ice.
