According to historical records, sailing activities for sports and entertainment first appeared in 70 BC. Modern competitive sailing appeared in Europe in the early 17th century, and has become one of the most popular sports and leisure activities in coastal countries and regions around the world.

The sailboat mainly uses the sail to run on the wind. The wind blowing the sail brings a forward force to the boat. Such a simple source of power has a great structure. Let us understand the structure of the sailboat together.

Sailing boats are mainly divided into five categories: keel boats, stable board boats, multihull boats, ancient sailboats and windsurfing boards. Keel boats are complex in structure, expensive, and require multiple people to operate. Steady board boats are more compact, flexible, low-cost, easy to maneuver, and easy to popularize. Most of the Olympic events are such boats. Windsurfing refers to the sailor standing on one piece. Sailing on a skidboard.

Walking on the seaside, we can often see a curved sail on a ship in the distance, as if the slightly curved sail has become the symbol of the entire sailboat. This slightly curved part is the leading edge of the sail where the wind first hits, it is at the front of the boat, and the trailing edge of the boat's wing is called the trailing edge of the sail. From the leading edge to the trailing edge of the boat, the air-filled sail is called the windward side, and the protruding side is the windward side.

The sailboat mainly relies on the sailor to control the size and direction of the sail, so that the wind can drive the hull to turn, but at this time, the sailor needs to judge and control according to his own experience. Relatively speaking, the monohull sailboat has a small space and poor stability. When encountering wind and waves, it will swing violently, which is a test of people's ability to use the wind. However, this kind of sailboat has a relatively perfect structure, which is more conducive to people moving forward in the wind and waves. The catamaran and multihull sailboats sail smoothly, with higher safety, and can sail in the shallows. But it's heavier, so this type of sailboat is slow and expensive to manufacture. Therefore, the selection of sailboats also needs to select the appropriate hull and sails according to the actual sailing conditions.

Because sailing is relatively easy to get started and very environmentally friendly, it has become a hot water sport, and it is a popular item for tourists on large beaches. And sailing from children to the elderly, you can try as long as you want, and there are very few restrictions on people. So after learning about sailing, do you want to also participate in sailing and feel swimming in the undulating waves?
