The history of surfboards

As early as 1778, British explorer Captain J. Cook had seen this kind of activity in the Hawaiian Islands. After 1908, surfing spread to some countries in Europe and America. Spreading to Asia after 1960. In the past one to two decades, surfing has developed greatly. Large-scale surfing competitions have been held on the coasts of North America, Peru, Hawaii, South Africa and eastern Australia. Surfing is powered by waves and is carried out on the beach with wind and waves. The height of the waves should be about 1 meter, and the minimum should not be less than 30 cm. The Hawaiian Islands have waves suitable for surfing all year round. Especially in winter or spring, there are waves from the North Pacific Ocean. The waves are as high as 4 meters, which can make athletes slide for more than 800 meters. Therefore, the Hawaiian Islands have always been the center of surfing in the world.
The surfboards originally used were about 5 meters long and weighed 50 to 60 kilograms. After World War II, foam plastic panels appeared, and the shape of the panels was improved. The surfboards currently used are 1.5-2.7 meters long, 60 cm wide and 7-10 cm thick. The boards are light and flat, with slightly narrower front and rear ends, and a stabilizing tail fin at the back and bottom. To increase friction, the board is also coated with a waxy outer film. All surfboards weigh only 11 to 26 kilograms. Humpback whales have some corrugated structures on the front side of their wings, which help the behemoth move more gracefully and smoothly through the current. This structure helps reduce drag and helps the humpback "grab" the current, ensuring that it can move nimbly despite its massive size. Inspired by this, surfboard manufacturer Fluid Earth has produced characteristic surfboards with corrugated front ends.
