Railwork describes the art of shaping the rails of a surfboard and is an important factor in how the board will perform in the wave. The rails of the surfboard are thereby sanded and brought into the desired shape.
When choosing the shape, it all depends on what the board should be able to do. Round rails with a lot of volume give the surfboard uplift, even in the turns. This will make the surfboard more forgiving of mistakes. Thin and sloping rails dig better into the water surface and allow more aggressive maneuvers. There are also board shapes where the rails have an edge at the bottom. This ensures that the water can better release from the surface of the board after a turn. This is especially in the tail area of the surfboard a popular rail shape, because you lose less speed after turns.
