Bottom Contour
A surfboard with a flat bottom thrives in small mushy surf and provides the ability to make quick and loose turns. As the wave's height and speed increase the board becomes more difficult to turn and shift.
The main purpose of a concave bottom is to lead the water flow down the length of the surfboard. This forces the water out of the tail and adds more responsiveness to the surfboard. Concaves are a very important feature when looking to improve the manuverability of the boards tail while turning.
Vee is used to provide a looser tail at high speeds and increases the rockerin the center which helps the board turn more easily. The basic concept of the Vee is to allow more controlled turns at sharper angles.
