Conversely, if the nose and tail increase in width and the center remains the same, the rails become more parallel, complimenting the nose ride but decreasing the maneuverability because there is little curve to cause drag in the turn. As the board gains stability, it also gets more difficult to tip on a rail to turn.

If the nose and tail remain the same and the center width increases, the board gains stability. The three measurements work in concert, and as one grows or reduces, it affects the others.

Boards that are wider in the mid section are more stable but are more difficult to turn because they don’t tip up on a rail as easily as their narrower counterpart. As the tail design gets wider it becomes more and more stable but this will make it difficult to tip on an edge to turn. When the surfboard drops into a wave, a wider the tail will captures more water, thus causing better lift. The down side of this is that widening the nose adds more volume of material or swing weight in front of you while turning, so the ease of turning diminishes. For example, as the nose becomes wider, it becomes more stable to stand there. But each of the three measurements does provide its own defining contribution to the board’s performance, and with that contribution usually comes some sacrifice to another aspect of the board’s performance. These dimensions give only a general idea of the board’s shape because varying intensities on the outline curve cannot be told with just three measurements.Īlthough much of the board’s riding characteristics can be attributed to the outline, one must realize that it is simply one element in a much larger assemblage of contents that makes up the final shape.

Measurements are taken one foot from the nose, at the widest point in the center section, and one foot from the tail. The outline, or plan shape is the curve that forms the outer edge of the board when observing from the top or bottom of the board.
