Water rafting knowledge

Floating on the water, moving with the water. Drifting was once a primitive way for humans to wade through water. Rafting originated from the Eskimo leather boat and the Chinese bamboo raft, but at that time it was to meet the needs of people's life and survival. Rafting became a real outdoor sport, which began to develop after World War II, and some people who like outdoor activities tried to use retired inflatable rubber boats as rafting tools, which gradually evolved into today's water rafting sport.

Whitewater Rafting has a very sentimental term called "White Water Rafting". White water refers to the waves formed after the collision of running water and rocks, the white foam at the end of the wave, and people are like silver barracuda floating in the sparkling light.

According to the standard, the river is divided into 6 levels from Ⅰ to Ⅵ according to the coefficient. Class I indicates smooth water flow with few obstacles. Level VI means it is almost impossible to pass, posing a serious risk to life. People who are able-bodied and not afraid of water can cross Class I to III rivers. The more challenging level IV requires you to be active, confident in the water, and have rafting experience. Compared to Class IV, Class V is a big leap forward, this class of rivers have long and continuous rapids. The steep, narrow waterway is strong enough to overturn a kayak, and swimming in the fast-moving Class V river is a tough test.
