Here is a goodexplanation. (click "explanation") rocker - Rocker is an upside down arch or downward curve in your ski or snowboard from the tip to tail. The rocker shape is similar to a rocking chair. Another good way to think about rocker is to picture the shape of your favorite surfboard, wakeboard or waterski. All of these have rocker. You will hear rocker referred to many ways, including but not limited to: reverse camber, inverse camber, banana, early rise, s-rocker, gull wing, three stage rocker, negative camber, R.C. Technology, Rocker 6, elf shoe and of course, my favorite, the Young-Whippersnapper's-Powder-Slaying-Weapon.
