Surfboard is a kind of sports equipment used for surfing. The original surfboard was about 5 meters long and weighed 50-60 kg. After the Second World War, foamed plastic plates appeared, and the shape of the boards improved. The current surfboard is 1.5-2.7 meters long, 60 cm wide and 7-10 cm thick.

All surfboards weigh only 11 to 26 kilograms.
