Also boards that are shorter tend to offer more front to back control. More important than the boards shape however is it's overall size. A larger board will turn slower but go further and faster. For more information check out the board size section . Thickness Thickness also contributes to how far a board travels over the water.
Thick boards travel further but remember that added thickness also contributes to added weight.
Also thick boards do not turn as well as thin ones. They tend to be less responsive. Rocker Rocker is the amount of curvature in the nose of the board. The purpose of rocker is to help you make the transition from the sand to the water as smoothly as possible. Obviously a lot of rocker would be desirable for this purpose but unfortunately too much rocker makes a board slow.
