Skimboards are designed for surfing on shallow water or wet sand. They are smaller and thinner than surfboards, usually less than two and a half centimeters thick, which makes them less buoyant. They are usually oval or teardrop-shaped, with a slight bottom curve near the nose.
Most skimboards consist of a high-density PVC foam core enclosed in a sheet of fiberglass or carbon fiber, stiffened with a thick resin layer. A rubber sheet called a stomp pad is sometimes placed at the bottom to provide traction. This bought and installed separately, or substituted with surf wax.
