- Bevels - the transition area between the
ski's sidewall and the ski's base. Sharper,
flatter bevels keep the ski riding smoother,
rounder and higher in the water. Larger bevels
allow the ski to ride deeper in the water.
- Concave - the edge-to-edge channel that
runs down the ski base.
- Dampening - the reduction of ski vibration
- Fin - the underwater foil on the tail of
the ski that aids in turning and tracking.
- Fin box - the device that secures the fin
to the ski and allows the fin to be adjusted fore
and aft, as well as up and down.
- Length - the measurement in inches from
the ski's tip to tail.
- Longitudinal flex - the measured amount in
which the ski flexes along its length.
- Off-side turn - a turn to the right for a
left-foot-forward skier; a turn to the left for a
- On-side turn - a turn to the left for a
left-foot-forward skier; a turn to the right for
a right-foot-foward skier.
- Profile - the outline of the ski when
viewed from the top or bottom.
- Rocker - the difference between the height
of the ski tip and the center of the ski body,
and the difference between the height of the ski
tail and the center of the ski body when the ski
is placed on a flat surface and viewed from the
- Torsional flex - the measured amount in
which the ski flexes along its width or the
amount in which the ski "twists".
- Tunnel - the recessed channel that runs
down the center of the ski base.
- Weight - the physical mass of the ski.
- Wing - adjustable foil on the side of the
fin that aids in decelerating the ski during a
turn at shorter line lengths.
