sailing originated in the Haihe River area living in ancient people's water transport. The modern sailing in Holland. In 1870 America and Britain held the first cross the Atlantic in America's cup. Sailing is divided centerboard and keel sail boat sail boats two. Steady light to board the boat sails flexible, moving in shallow water, also known as keel sail boat rudder to steady the boat, the body is not flexible, good stability, strong fan, can only travel in deep water. Competition in the sea, the site consists of 3 buoys equilateral triangle, the length of each channel is 2 ~ 2.5 nm. The game as a navigation buoy, a total of 7 games, which take the best of 6 games and assessment scores, scores less rank.

is the first method of calculation for each 0 points, second 3, third 5.7, fourth 8, fifth 10, sixth 11.7, seventh 13, follow-up of each ranking points plus 1.

The principle of



sailingThe power source

sailing: maximum power sailing is the source of "Bernoulli effect", that is to say when the air flows through a similar cambered wing, will produce a forward and upward attraction. Therefore, the prevailing wind direction sailing will it be possible to move a point. And is sailing downwind, "Bernoulli effect" disappeared, but ships can not reach the highest speed.

Course restrictions and benefits of



sailing

sailing course but is not completely restricted, in the prevailing wind is about all about 45 degree angle, is unable to produce effective power forward.

but the wind is not too good, then "Bernoulli effect" disappeared, the speed will slow down again, but also into the unstable state.

sailing against the wind and the ability of the ship, to go against the wind direction, must take the shape of Z route to reach the destination.

so, can not effectively curved fan Zhang, there is no ability to sail against the wind. These vessels sailing in the sea, often rely on seasonal change the direction of the trade winds, in order to have back. Like a modern sailing, have good ability to sail against the wind.
