Most surfers fit into one of two categories in their surfing approach. One being a down the line, speed oriented, skatey style. The other is a more vertical, snappy, in the pocket style. The type of wave you surf the most will influence your approach, but generally a surfer's approach is similar in all types of surf. With that in mind, each approach requires a different bottom rocker. Down the line boards are generally flatter from nose to tail. Vertical, in the pocket boards have more overall curve.

When ordering a board it is important to assess your approach and the waves you surf to dial in a curve that fits your individual style. The best way to do this is to work with a shaper who keeps detailed measurements of bottom rocker and can make accurate changes to those dimensions to suite your style and keep you progressing in the direction you want to go.
