Surfboards are sports equipment that people use for surfing. The surfboard originally used was about 5 meters long and weighed 50-60 kilograms. After the Second World War, foamed plastic boards appeared, and their shapes were also improved. The current surfboard is 1.5~2.7 meters long, 60 centimeters wide and 7~10 centimeters thick. It is light and flat, and its front and rear ends are slightly narrow. There is a tail fin at the bottom of the back that acts as a stabilizer. In order to increase friction, a waxy outer film is also coated on the board surface.

Surfing is driven by waves and should be carried out on the seashore with wind and waves. The height of the waves should be about 1 meter, with a minimum of not less than 30 cm. The Hawaiian Islands have waves that are suitable for surfing all the year round, especially in winter or spring when waves come from the North Pacific Ocean. The waves are as high as 4 meters, which can enable athletes to slide more than 800 meters. Therefore, the Hawaiian Islands have always been the world surfing center.
