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 a water sport in which athletes stand on surfboards, or use webs, kneeling boards, inflatable rubber mats, rowboats, kayaks, etc. to control the waves. No matter what equipment is used, athletes should have high skills and balance ability, and be good at long distance swimming in wind and waves.
