As early as 2003, rocker skis and boards were introduced to the ski world. However, this technology is nothing new, as water skis and wake boards have taken advantage of the rocker design for many years. Recently, these skis/boards became increasingly popular. Now what is it that makes a rocker design and why is it effective?
First we must look at the traditional shapes available. Since the parabolic shape has become the standard, consider this ski/board as our basis. To describe rocker, a concept of camber must be understood. The traditional ski has a camber. While laying a ski/board riding side down on a flat surface, it can be seen that the center (under the binding) does not touch the underlying surface. Once pushed downward, the flex allows the board to touch. This upward curvature is called camber. It is the camber, in conjunction with the parabolic shape, which allows the rider to carve turns once on edge.
The newer design for skis/boards is rocker or reverse camber. Now if we do the same thing as with our traditional ski/boards and lay a rocker flat on the surface, the board will touch the underlying surface in the center. The ski/board will flare up at the tip and/or tail. Ski manufactures have produced many variations of rocker skis. The degree of rocker can be from extreme to moderate.
All skis including camber and rocker produce a rocker shape when pressure is applied while turning on edge. A traditional camber board puts more pressure on the tip and tail in the curve as it must flex in order to turn. A rocker ski/board requires less energy to initiate a turn. With the shape of the ski already in a “flexed” position, the ski engages more quickly and effortlessly.
By combining these technologies, manufactures have produced skis and boards that fit all types of terrain and riders abilities.
