Environmental requirements of sailing.

Environmental requirements of sailing.

Sailing needs an environment, and many people will do some appropriate exercises to ensure their health. This sport is still relatively high-intensity, and a full state is more conducive to us to actively meet life. If you want to exercise yourself, you can consider this sport and look at the environmental requirements and knowledge of sailing with me.

Environmental requirements for sailboats 1 1, environmental requirements for sailboats.

The formal sailing competition is required to be held on the high seas, and the distance from the coast should be 0.5 ~ 2 kilometers. Sailing competitions in the Olympic Games usually adopt Olympic trapezoidal routes and windward and downwind routes.

The departure route consists of an imaginary line between the flagpole of the departure ship and the flagpole of the left ship or buoy. The finish line is also a virtual line.

The virtual connection line between the terminal ship, flagpole, flagpole or buoy of the left ship is the finish line, and its width is generally 50 ~ 60 meters, so that the referee can clearly observe the situation of each sailboat (board) passing through the finish line.

2. The sailing venue changes at any time.

Due to the constant changes of wind direction, wind speed, meteorology, hydrology and other conditions, the competition venue is not fixed. It is arranged according to the meteorological and hydrological conditions of the designated area (the chart position of this area should be notified to the contestants before the game). The venue layout is usually completed half an hour to five minutes before the start of the game. All kinds of sailboats (boards) set sail at the same time. Due to the open water surface and heavy wind and waves, the start-stop signal is to raise the signal flag on the departure ship and send out strong audio signals (such as flares and gongs).

3. What is the dynamic principle of sailing?

Most people often think that sailing boats are driven by the wind. In fact, the power of wind acts on the sail in two forms, and the biggest power source of sailing is the so-called Bernoulli effect.

According to Bernoulli's principle that "the flow rate increases and the pressure decreases", when the air flows in one direction, the force acting on the side will be relatively reduced. That is to say, the greater the gas velocity, the greater the dynamic pressure and the smaller the static pressure. The smaller the flow velocity, the smaller the dynamic pressure and the larger the static pressure. In this way, the place with low gas velocity will produce a lateral pressure on the place with high gas velocity, which is called static pressure. When sailing against the wind, the ship is propelled by the static pressure of the wind.

Classification of sailing competitions

1, the first category is keel ship.

The hull is 6.5-22 meters long, and an iron rudder or a lead rudder protrudes from the middle and lower part of the hull to stabilize the hull and reduce the lateral movement of the hull. Because this kind of ship has large hull, good stability and strong sails, it can only travel in deep water. Small keel ships need 2-3 people to operate, and large keel ships need more than 15 people to operate.

2. The second category is the stable board ship.

There is a slot in the middle of the hull, which can be used to place the stabilizer. The fixing rod can move up and down as required. The maximum length of the hull is 6 meters and the minimum length is 2 meters. Because of its light hull, simple equipment, easy manufacture and flexible driving, it can sail in shallow water. A stable ship can usually only be operated by l-2 people.

3. The third category is the multi-body boat.

Engaging in sailing can enhance physical fitness and cultivate tenacious spirit of fighting wind and waves; You can master a variety of navigation techniques under various climatic conditions, which is of practical significance for improving navigation knowledge and navigation ability.

Teenagers participate in sailing.

The life of sports lies in mass participation, and the basis of mass popularization is teenagers. Let young people have the opportunity to experience the charm of navigation, learn navigation knowledge, enhance their practical ability, cultivate children's awareness of being close to and caring for nature, and realize all-round exercise in morality, intelligence, physique and beauty.

At present, many cities with conditions have formulated distinctive youth sailing plans, and incorporated the popularization of sailing knowledge into the school teaching system, talent training system and event training system. Through the establishment of youth sailing clubs, characteristic schools and training camps, the basic conditions for youth sailing training can be met. Qingdao municipal government has been committed to supporting the development of youth sailing.

Since ancient times, it has been a common dream of mankind to sail to the ocean with passion. Introduce and promote new sports and lifestyles, and introduce an international sailing training system to help you enjoy it.

Environmental requirements for sailing 2. How can sailing be more exciting?

Most people often think that sailing boats are driven by the wind. In fact, the power of wind acts on the sail in two forms, and the biggest power source of sailing is the so-called Bernoulli effect. This is the basic knowledge that sailing should master in water sports.

Water sports skills are not so difficult to learn. For sailing beginners, we should first learn to understand nature and observe, and cultivate a high sensitivity to the romantic ocean currents and their changes. This means that if you must always pay attention to the wind direction, weather, waves, current and distance from the shore. For a person who lives in the ocean all the year round, it may be an extremely mechanical and boring job, but for urbanites who have been out of marine civilization for a long time today, it is extremely enjoyable.

Water sports skills Sailors need to know the wind direction when sailing. At this time, they can best recall some of the oldest instincts of athletes. To be a qualified wind catcher, they must have special judgment. So sailing needs more intelligence. In addition to the necessary rest, athletes should also have rich instinctive wisdom and acquired judgment. Only by keeping the wind and sails at the right angle can they move forward quickly.
