Chapter 279: Sail

"Yes, remember."

Zhou Yi also whispered to Zhao Xu.

The two looked at each other and everything was self-evident.

After giving Zhou Yi a few more instructions, Zhao Xu, Chen Shou and others returned to Pingcheng City.

Because it's getting late, we won't be able to return to Yancheng until tomorrow.

He simply called Chen Shou and discussed with him the details of the construction of the sail warship.

For Chen Shou, although King Yan gave him the drawings.

But I don’t quite agree with the existence of some unique structures on the sailing battleship.

Then he said: "Your Highness, I don't understand why the sails on this ship need to be soft sails instead of hard sails. It seems that hard sails require fewer people to maneuver."

Zhao Xu nodded slightly.

After a detailed discussion, he was quite certain of Chen Shou's shipbuilding skills.

He can basically tell you the structure of a battleship.

He also understands the different functions of hard sails and soft sails.

The two disputed which structure was optimal.

"Hard sails do require fewer people to control the sail, but hard sails have a disadvantage, which is that the wind-eating area is small and cannot increase the speed of the warship. Soft sails have a large wind-eating area, which can increase its speed at sea." Zhao Xu said.

In modern times, most ships in ancient times and Dasung use hard sails.

This kind of hard sail has a dense keel, so the sail will not be greatly deformed when the wind blows.

Soft sails have fewer keels and will show a large arc when the wind blows, so the area affected by the wind is larger.

This is just like a kite. A single-sided kite is definitely not as powerful as a tube-mounted kite.

Same principle.

A soft sail would give the battleship more power at sea.

"That's it." Chen Shou suddenly realized.

He continued to ask: "Then why are the buildings on the battleship moved to the hull?"

"This is a question of the center of gravity. If the center of gravity is down, the footplate will be more stable, and the ship will be more resistant to wind and waves when sailing on the sea." Zhao Xu explained patiently.

Dasong's boats have a special feature, such as building boats.

This kind of ship has a house-like structure built on the deck.

This results in the top being heavy and the bottom being light.

This structure can hold more troops for boarding battles, but it can easily capsize in strong winds and waves.

Therefore, this structure is not bad for navigation in inland rivers and offshore waters, but it will not work when encountering strong winds and waves in the ocean.

"Focus?" This word is new to Chen Shou.

Seeing Chen Shou's confusion, Zhao Xu explained what the center of gravity was.

When Chen Shou heard this, his eyes gradually changed when he looked at Zhao Xu.

Just now, when King Yan asked him about the construction of warships, he spoke clearly and clearly, and he was still a little proud.

Now after two questions, he found that King Yan was hiding something secretly.

He doesn't understand these things either.

His own master never taught him this.

"If you still have something you don't understand in the future, I will go to Yancheng often to ask His Highness for advice." Chen Shou was like a student at this time.

Zhao Xu smiled and said: "That's okay, but Mr. Chen, don't belittle yourself. Your shipbuilding skills are indeed good. It's just that the ships that have always been praised either travel on inland rivers or offshore, and there has never been a need to cross the sea. You guys These shipwrights just don’t think about these structures.”

Chen Shou nodded and had to say that King Yan really made the point.

Even he had never thought of going deeper into the sea.

So when he saw the blueprint of a battleship that King Yan said could go deep into the sea, he was moved and wanted to try and challenge himself.

"Your Highness, please continue to explain to me why this battleship does not use watertight cabins?" Chen Shou pondered for a while and then asked.

King Yan will go back tomorrow, and he doesn't want to miss this opportunity.

Not only must he be able to build it, but he must also understand everything about this battleship.

"The watertight cabin can certainly make the warship resist sinking, but it makes it impossible to thicken the hull and lay multiple decks. As a result, the warship's anti-strike ability is weak and it has fewer artillery guns."

The drawings he gave Chen Shou this time were actually designed with reference to the Galen ship.

This kind of ship has a multi-layer superimposed hull, which is half a meter thick. It is very strong and has strong resistance to shelling.

At the same time, a diagonal rib structure is used to lay multiple decks, and each deck can be equipped with a large number of artillery.

It adopts soft sails, has a large wind area, and can sail at extremely high speeds.

The disadvantage is that soft sails are troublesome to operate and require a large number of skilled sailors.

Simply put, this kind of warship is suitable for ocean going and naval artillery battles.

But in the offshore, the wind direction changes quickly, and this kind of warship is not as good as the hard sailing ship of Da Song.

Therefore, in the end, the functions of the two ships are different.

One is suitable for use as a battleship, and the other is suitable for commercial use.

Dasong never wanted to conquer the ocean and explore other continents.

Emperors of all dynasties thought that China was the world.

Naturally, craftsmen will not be allowed to explore ocean-going ship technology, and it is really not the craftsmen of Dasong who can do it.

until midnight.

Chen Shou was really embarrassed when he saw that Zhao Xu kept yawning, so he left with satisfaction.

The next day, although Zhao Xu was very sleepy, he still got up early.

Chen Shou sent Zhao Xu outside the west gate of Pingcheng City before going back reluctantly.

For him, he finally had a confidant in the matter of shipbuilding.

After more than one day, Zhao Xu arrived in Yancheng.

When he returned to the palace, Luan'er took off his fox fur and brought him a hand stove.

He sat down and gave him a squeeze on his shoulders and a pat on his back. He was very obedient.

At this time Feng'er also came over, her pretty eyes filled with authority.

But when she saw Zhao Xu, she immediately turned into a charming girl.

Seeing this, Zhao Xu joked: "Hey, who offended Butler Feng again."

"Puff..." Feng'er couldn't help laughing when she heard that.

She came over and pinched Zhao Xu's right arm, and said in a tender voice: "Your Highness, you don't know that yesterday, someone from the Xie family came to give a gift. There was a vase in it. Just now, a maid accidentally broke it. I said a few words to her, and she argued with me."

"The Xie family is here?" Zhao Xu heard the key information from Feng'er's words.

"Hehe..." Luan'er covered her mouth and laughed at this time. She said to Feng'er: "Look, I said that Your Highness would not care about these trivial matters."

"You know." Feng'er reached out to scratch Luan'er, and the two of them played for a while.

Then Feng'er said coquettishly: "Your Highness, the affairs of the palace are also matters."

Zhao Xu came back to his senses and laughed, "I have called you Feng Butler, so the affairs of the palace are naturally up to you. The country has its own laws, the family has its own rules, and the palace naturally has its own rules. If there is punishment, it must be punished."

Feng'er laughed, and this Feng Butler made her very useful.

But at that time, the King of Yan just casually said that he wanted her to manage the palace.

Now many servants in the palace thought that she was a personal maid of the King of Yan, so she liked to meddle in other people's affairs.

So she told this story.

After hearing this, Zhao Xu finally understood why Feng'er was aggrieved.

He said, "Okay, I will write a handwritten order to officially let you be the housekeeper and satisfy your desire to be a housekeeper."

Luan'er is quiet and only likes to do needlework.

But Feng'er can't sit still. If you don't give her something to do, she will make trouble.

"Thank you, Your Highness." Feng'er was overjoyed and was much happier when her arms were pinched.

Zhao Xu shook his head helplessly and said to her, "Then the first order I will give you as the housekeeper is to invite the people of the Xie family to the palace."

"Yes, Your Highness." Feng'er responded with a yes and left with light steps.
