"The house is noisy, come here to relax, can you be sure to win this year?" Hong Tao really doesn't have any purpose, he is just lazy to work, and he doesn't want to watch everyone busy and do nothing.

"It's hard to put into words...... Don't hide it from Brother Wang, the younger brother has been in office for more than two years, and he has never won the dragon boat championship, ashamed and ashamed...... "When he heard the topic of the dragon boat race, Wang Guan's face was full of helplessness.

"Why is it so unbearable? The soldiers train very hard, and they all know the nature of the water, is it possible that there are people who are better at dragon boats? ”

This answer surprised Hong Tao a little, the Water Tiger Wing itself is a regular sailor, and they are likely to be ineffective in fighting or something, but the sport of rowing competition is the strength of the Water Tiger Wing. They usually have nothing else to do, except for fiddling with the building boat, which is dragon boat training.

"Brother Wang doesn't know that it is Shui Hujie who wins the championship every year. The dragon boat they don't know how to build is extremely fast on the water, and other ships can't reach it......" Speaking of the reason, the crown shook his head again and again, and he didn't have the slightest intention of winning, it seemed that he was subdued.

"Dragon boats are different?" Hong Tao has never seen an ancient dragon boat race, let alone paid attention to the rules of the competition.

At this time, the rules of dragon boat racing seemed to be different from those of later generations, there was no limit to the type of boat, and there was no limit to the number of people, if you thought that you could win by rowing alone, you could still participate in the competition.

Therefore, the participating teams have their own dragon boats, and they will sail down the Bianshui into Jinming Pond before the start of the race, which is usually invisible. The team called Water Tiger Jie is also a water army in the forbidden army, but the camp is not in Jinmingchi, but in Yujin Garden in the south of the city.

Their dragon boats are said to be made by Jiangnan craftsmen, and they are slender and long, light in weight, and shallow in draft, although there are two fewer sailors than water tiger wings, but they are much faster when rowed, and they have won three championships in a row.

Water Tiger Wing and Water Tiger Jie are the only two water armies in the capital, and they also have no combat missions, all their work is to patrol the river, plus a water show or something during the New Year's Festival, and the only thing that can distinguish the superior is only at this time.

However, the Water Tiger Jie relied on this dragon boat to firmly suppress the Water Tiger Wings, which made the crown very depressed. Although the emperor did not blame him for this, there is no need for others to say that this is not a good job, and the attention and promotion opportunities he has received will naturally be less.

"I have a way to make Brother Wang win, I don't know if I want to try?" Hong Tao is also idle and painful, this festival is not interesting, and when he heard the description of the crown, he suddenly remembered a funny thing.

"That's true!" Wang Guan was born in the navy, and in the past few days of contact with Hong Tao, he has talked about the advantages and disadvantages of the building ship, whether he knows how to know it as soon as he hears it. He doesn't have the right to modify the boat, but the dragon boat can.

"It's really not true, I don't dare to pack tickets, but Brother Wang has no hope of winning the championship, so it's better to give it a go. I don't have trouble with this method, I just need to add a few crossbars to the dragon boat, and then change the oars. If Brother Wang is willing to transform the dragon boat, I will bet ten times on behalf of the brothers of the Water Tiger Wing, and after winning, the gambling capital will be returned, and all the profits will go to the soldiers, which can be regarded as giving everyone a holiday reward! ”

Every time Hong Tao comes to Jinmingchi, he can see the dragon boat with water tiger wings, more than ten meters long and one meter wide, twelve oarsmen each have a single oar, and there is a drummer at the stern. Not only did they have to row, but they also had to control the direction of the boat according to the drummer's instructions, because there were no rudders.

There is still a lot of room for improvement in this dragon boat, and the main body will not move, so it will be too late, but adding some accessories will definitely increase the speed significantly.

For example, the single long oars of the post-world racing boats were replaced, and a stern rudder was added, which was operated by the drummer with his feet. In this way, the thrust is increased, and there is no need to be distracted to control the direction of the boat, and the chances of winning will be much higher.

But because he had never seen what the dragon boat of Shui Hujie looked like, Hong Tao was not 100% sure that his method would work, so he could only bet on it and give an explanation to the crown.

"Just according to what Jin Qing said!" The crown thought a little and made a decision. In fact, there is no loss for him, maybe there is still a chance to change, if he doesn't change, there is no chance, he will definitely lose!

With the order of the crown, dozens of forbidden soldiers immediately carried another dragon boat onto the dock shelf, and the craftsmen in the shipyard began to prepare materials according to Hong Tao's request.

The first is the oars, which are made of carbon fiber and fiberglass, each 1.8 to 2.4 meters long, adjustable in length, and weighs only about one kilogram.

The only material Hong Tao can choose is wood, and there are ready-made camphor wood in the shipyard, and the thinnest one is also thigh-thick. The weight is a little heavier, but the strength should be enough. It is estimated that the sailors at this time are not so squeamish, and they may not be used to the oars that are too light.

The whole camphor wood is cut into 7 feet long, and then broken into two pieces with a large saw, and the rest has to be sharpened by hand by craftsmen. To cut this half of the wood into a whole oar, the grip must be oval, the blade and the grip are not perpendicular, and there must be a declination angle of about 10 degrees.

This allows the paddle to be smoothly inserted into the water when the arms are stretched forward, and gradually emerges from the water as the arms are retracted, allowing for the most efficient strokes.

It is the highest efficiency but not the highest power, if the paddle is completely perpendicular to the water, the force is large, but the resistance is also large, too laborious.

As for how the data of this 11-degree declination came from, Hong Tao really doesn't know, it must have been calculated by a large number of experts in later generations, and it has been verified by many professional rowing teams for decades, so it can be used with confidence.

Another problem is the bracket of the oar, such a long oar cannot be controlled by both hands alone, it must have a fulcrum as the center of the circle, and this center of the circle is the top of the bracket.

In later generations, the paddle frame and hull of the boat were integrated, and the fixing bolts were left when building the ship. There are certainly no dragon boats now, but fortunately they are made of wood, so it is not difficult to fix them temporarily.

After the craftsmen understood the meaning of the horse and understood the drawings of the horse, they quickly found the strongest and easiest way to modify it.

An arm-thick piece of timber is fastened horizontally to both sides of the ship, and the wrong ends are sawed off in order of odd and even numbers, so that there are six oars on one side.

So how can the oars be fixed on the oars and still move freely? Later generations adopted a more advanced method, it had an escapement, which would certainly not be able to be built now.

But the craftsmen had a solution, and they put an iron hoop on the wooden handle of the oar, and under the hoop was an iron rod half a foot long. The top of the paddle rack is also tightened with an iron hoop, and a hole slightly thicker than the iron rod is made in the middle.

After the sailor got aboard, the iron rod on the wooden handle of the oar was inserted into the hole, and the oar could be rotated horizontally. But don't move up and down too much, as it will be easy to pull the rod out. Once out of the support of the oars, you will definitely not be able to control such a length of oars with your hands alone.

How to make the oars row smoothly without detaching from the water depends on training, so that the sailors must become familiar with this new type of oars, and change the habits of the previous oars. Judging by Hong Tao's experience in training sailors and the quality of these sailors, it should be possible to complete it in a few days, which is not a difficult task.
