Humpback whales have some corrugated structures on the front side of their wings, which helps this behemoth to move forward more gracefully and smoothly in the current. This structure can help reduce the resistance and help the humpback whale "catch" the current, thus ensuring that it can move quickly despite its huge body. Inspired by this, Fluid Earth, a surfboard manufacturer, produced a special surfboard with a corrugated front end.
Surfboards are lighter and less stressful.
The surfboard has a large area, which reduces the pressure brought by pressure very little, thus making it easier for people to ride on the waves.
Surfing skills
Surfing is a water sport. Athletes stand on surfboards or ride the wind and waves with nets, kneeling boards, inflatable rubber mats, rowing boats and kayaks. No matter what kind of equipment is used, athletes should have high skills and balance ability, and be good at dealing with wind and waves at the same time.
Middle and long distance swimming.
Surfing is that athletes lie down or kneel on the surfboard first, and then row to a place suitable for waves as a starting point. When the waves push the surfboard to slide, the athlete keeps the surfboard in front of the wave peak and stands, and his legs naturally spread back and forth (usually the balance leg is in front and the control leg is in the back), and his knees are slightly bent to slide quickly along the waves.
