"But it's so ......" Luo Dacai, who was standing behind, saw that his car and ship had run to the first, and the situation was superior, so he began to speak out again.

"Well, may! There is still a long way to go! Luo Youde is obviously much more generous than him, the housekeeper, and is still comforting Hong Tao. In fact, he now has a little belief that Hong Tao can build ships, although this small boat has a strange shape and strange sails, it is indeed very sensitive, and it is not something that a person who does not know how to build a ship can make up at will.

"Carl, they're saying we're stupid, what do you say we're going to do?" Hong Tao didn't pay attention to the two people behind him, but carefully paid attention to the overall situation of the new sailboat, and felt that the ride was quite stable, before speaking to Carl in German.

"They don't know how to sail, and we have two sails that are useless. I've seen it in the cabin, the water is normal, is it okay to raise the jib now? "Karl is in his country, half army, half navy, otherwise he would not have sailed and led the vanguard to be sunk by the enemy. Although he didn't learn much about Hong Tao's nautical knowledge, he was completely impressed. If the map wasn't drawn on the beach, Carl even wanted to secretly trace it, he felt that Hong Tao drew more accurately than the royal map of their country.

"Come, let them see what a sailboat is! If you win, the ship will be called Karl, and you will be the first captain! "Hong Tao is much more ruthless than fooling the Song people, and he throws all the ethereal things over, and he doesn't have to think about it. As soon as he heard that he had the opportunity to be promoted to captain, he immediately spat at the palm of his hand like clockwork, and pulled the cable is a jerk, and the front spinnaker weighing dozens of pounds let him pull it up in more than ten seconds. Then, like a big monkey, he jumped over the horizontal and vertical cables, and skillfully fixed the spinnaker on the front sail rope, and did not forget to stretch out a thumbs to the waves.

"Oh, Brother Hong is really powerful, it seems that the winner is difficult to decide!" Luo Youde saw that another sail was raised like a trick, and he quickly found the direction of the sail, and couldn't help but praise Hong Tao. This sentence is not polite, in the kind of hard sailing ship of the Great Song Dynasty, it is very difficult to raise the sail and adjust the sail direction, without a dozen skilled sailors to work together, it cannot be completed at all, and fixing the appropriate sail direction is a technical work, non-old boatmen can't. But Hong Tao and Carl did it, and it took only a minute before and after, even if the sail was not too big, but Hong Tao's skills were fully revealed.

"Hold on, the hull is about to tilt!" Hong Tao looked up at the weather vane on the top of the mast again, and then hit the steering wheel to the left, reminding Luo Youde and Luo Dacai by the way.

"Ah......" It's a pity that Luo Dacai still didn't believe Hong Tao and didn't obey, but after the hull turned slightly, the strong crosswind not only puffed up the two sails, but also tilted the sailboat hull to the right by more than ten degrees. If Hong Tao hadn't been prepared and grabbed Luo Dacai, he would have to plunge into the sea water on the starboard side.

"This ...... This...... Collect the sails! Collect the sails! It's going to flip! "Luo Dacai is also a familiar customer of running boats at sea, the hull is so tilted, and the sails are not closed, there is only one consequence, that is, the boat capsizes!

"Shh......h Don't panic, the best is still to come, you see, your car and ship are about to be caught up by me, right? Wait, I'll show you how fast my sailboat is! Carl, go to the cabin and take a look, and if it's okay, get ready to raise the sails! Hong Tao hadn't experienced this kind of wind and waves for a long time, and the blood in his body began to boil as the speed of the ship increased. Since you want to win, you have to win beautifully, although two sails can also win, but it is not enough to show that your shipbuilding skills are superb, you have to come on!

"Mazu bless! ...... "When the huge black sail was also raised by Karl, and slowly poked out of the bow of the ship, and was blown into a big bulge by the wind, the speed of the sailboat instantly increased, and the whole bow of the ship was pressed into the sea by the force of the wind, and then jumped violently, and the waves hit the bow to the stern like a waterfall, giving everyone on the deck a deep chill. The hull is tilted to almost 30 degrees, and the small half of the bottom of the boat is almost exposed, but it just does not turn over, whenever the hull tilt angle continues to increase, Hong Tao will quickly rudder to the right, so that the wind becomes a side wind, and when the hull is turned back a little, and then quickly rudder to the left, the hull begins to tilt more intensively.

This technique is the mastery of a high-speed racing yacht captain, and simply changing the direction of the sail to adjust the wind angle of the sail is too slow and time-consuming. As long as you can accurately grasp the performance and wind changes of the sailboat, you can also keep the sailboat from capsizing at high speed by quickly changing the course of the sailboat, and will not lose too much wind power. Don't look at the sailboat at this time is left and right back and forth, but its speed is basically not affected, sailing races, two sailboats close to each other to seize the upper hand, is used this technique to maintain the speed of the boat.

Can the sailboat of the Great Song Dynasty play like this? The answer is no. First of all, the sailing area of the sailing ships of the Song Dynasty was too small to reach this speed, and there was no need to operate it in this way. Secondly, the ships of this era are all inner keels, there is no stabilizer plate, it is impossible to tilt to 30 degrees, then it is really overturned. Finally, the understanding of sails is different, the sails of the Song Dynasty are mainly downwind sails, that is to say, the maximum propulsion can be achieved in the downwind state, and the competitive sails made by Hong Tao are side sails, once downwind, it can't run fast.

This principle is currently known only to Hong Tao in the world, provided that he is the only one who travels through it. It's called Bernoulli's principle, which is the theory of the aerodynamic layout of an airplane's wing. When the sail is blown, it is shaped like an airplane wing lying upright, and when the crosswind blows, the air passes through the sail at different speeds due to the shape of both sides of the sail, resulting in a pressure difference. This pressure difference is the most effective driving force of the sail, which is the thrust that can push up the hundreds of tons of aircraft, as long as the speed is fast enough, the speed of cutting the air flow is fast enough, the sailboat will theoretically run faster and faster, but theoretically, because it also involves the strength of the mast.

Travel? In less than ten minutes, the car and boat, which were originally ahead of three or four hulls, had been thrown hundreds of meters behind them. The eight big men tried their best to eat, but they still couldn't even eat the wake of the sailboat, and could only watch as this strange fellow with huge black sails on three sides flew farther and farther away as if it were flying on the sea. After another quarter of an hour, the car and ship simply stopped chasing, and turned around and returned directly, admitting defeat, not comparing, too much to hit self-confidence!
