While introducing the new 2002 skis to you, we thought it would be helpful to define some of the terms and characteristics associated with skis and skiing styles so that you are prepared for the information on the following pages.
Fin: A normally metal protrusion at the tail of the ski that is a key ingredient in determining tracking, turning and riding characteristics of the ski, depending on its shape and size. Many are adjustable in dimensions, which allows the ski to be fine-tuned for its owner.
Wing: A small, horizontal fin that attaches to the main fin that aids in holding and stability. Wing angle is adjustable, normally between a range of 5 and 15 degrees. While the wing adds drag to the ski, it enhances the ski’s holding and performing characteristics that, if used correctly, can improve the skier's course position.
Caliper: A measuring device that provides very precise dimensions (to a thousandth of an inch) for the fin. This tool enables the skier to manipulate the attitude of the ski through minute adjustments of fin dimensions, to suit his or her skiing needs and style. Common dimensions of concern are fin length (tip to tail), fin depth (at maximum) and distance from the tail.
Wing Angle Gauges: Tools that are cut (normally in sheet metal) in incremental angles that can be placed between the wing and the bottom of the ski to ensure accurate setting of the wing angle.
Concave: Refers to the shape of the bottom of the ski being arched or curved inward. This shape provides two distinct edges, or rails, and promotes tracking.
Tunnel: Like a concave, but narrower, with flat spots on the sides. Promotes a smooth and predictable but often less aggressive ride.
Bevels: The bottom outside edges of the ski that have been shaped to allow the ski to sit in the water slightly deeper. The size and shape of the bevel affects both the ski’s attitude and speed. Larger bevels cause the ski to ride deeper (increased tracking and security) but become slightly slower, while smaller cause the ski to ride higher but faster.
Ski Flex: The amount of pressure that is required to bend a ski that when released will allow the ski to return to its normal shape. The flex contributes to how easily the ski will turn as well as how fast the ski rides. Generally, softer flexes facilitate turning, while stiffer flexes are faster.
