Of course, this modular production is only suitable for large-scale mass-produced ships. At present, the Ming Dynasty only has several official shipyards operating in Longjiang Factory, Qingjiang Factory and Suzhou Factory.

In the private shipyards in Fujian and Guangdong, every ship is still staked on site by masters, so every ship built in the south is different, and most of them are crooked.

Then Mr. Zhao came to the tent workshop and visited the process of sailors weaving sails with bamboo strips. Whenever they weaved a tent, they would clamp into a tent with a tent reins as a backbone, so that they could not only fold one piece by one, but also let the sails rise tightly against the mast.

In terms of performance, this bamboo scattered sail is certainly not as good as a canvas sail, but when used on transport ships and merchant ships, this affordable and durable sail is enough.

Then in the oyster shell workshop, he saw the workers crush the collected oyster shells and then send them to the kiln to burn lime. The calcium carbonate content of oyster shell ash is more than 90%. Lime sintered at high temperature is most suitable for mixing tung oil and forming calcium tung oleate with excellent waterproofness.

Then mix it with hemp silk to make putty twisted material to fill the seams of the hull and the nail holes of the iron nails. Only brush oil once a year, you don’t have to worry about the hull leaking, and it can also prevent the iron nails from rusting.

Zhao Hao asked Blanco, the chief ship maker on the Oriental Beauty, that European shipyards used oiled hemp fiber twill seams and coated with a layer of asphalt to make tar waterproof.

Not only is toxic, the tar is not as waterproof as the putty twist of the Ming Dynasty... When Zhao Hao returned on the Oriental Princess, he encountered water seepage in the hull. Fortunately, the treatment was timely, so there was no tragedy.

The entire punishment fleet went to sea for two months and almost no water leakage occurred. Well, this is also related to the fact that the fleet is full of new ships...

However, even if the old ship leaks, it is not afraid of it. The unique watertight cabin design of the Ming Dynasty can greatly improve the survivability of the ship.

Zhao Hao was in the ironwork workshop again and saw the blacksmith masters wearing naked upper body in the middle of winter, sweating profusely to create iron nails for ships.

Chinese ships have been using iron nails to fix ship boards since the Warring States Period, and by the Tang and Song Dynasties, the technology was fully mature. Zhao Hao saw that there were seven or eight types of finished iron nails created in the workshop. There were shovel nails, square nails, tartars, date pit nails, crawling nails, and flat nails... Obviously, they all have their own uses.

At this time, there was no iron nail on the European ship, and all of them were made of wooden nails. Although wooden nails were good as wooden nails, for example, they would not affect the accuracy of the compass and would not rust.

However, just by weaving tens of thousands of wooden nails into the board, the labor hours consumed will exceed the iron nails. This item alone is enough to make a clear judgment. Europe does not use iron nails at present, mainly because they are not good at iron smelting industry and are too expensive to afford.

Therefore, the shipbuilding process of the Ming Dynasty is still ahead of Europe in many places...

After visiting the workshops one by one, Mr. Zhao’s biggest feeling was that the boat is really not that easy to build!

No wonder Li Chao and Japan's shipbuilding level are not up, because this is a complex system project. If you want to improve the shipbuilding level, there are too many places that require tutoring. This is not something that can be done by hiring a few boatmen. You have to move the entire system over.

Bah, go dream!

After a quick look at the flowers in various workshops, it was already noon. Everyone followed Mr. Zhao to the third canteen of the shipyard for lunch... Secretary Ma said hello in advance. The young master was in a tight time and didn't hold a banquet. He just used some casually in the employee canteen. He also inspected the workers' food.

In the three canteens of the huge boat yard, there are rows of long tables that can accommodate 2,000 people to eat at the same time. There are two canteens like this in the boat yard. Otherwise, they would not be able to feed the entire factory area, craftsmen, apprentices, security guards, and civilians, a total of more than 5,000 mouths.

The cafeteria was filled with people. After Mr. Zhao and his party came in, their voices suddenly lowered a lot.

"Eat yours." Ma Hu waved his hands quickly, and the workers continued to bury their heads to eat.

The shipyard uses meal supplementary products, with 600 yuan per person per month, and is paid with the wages.

There are not many dishes in the cafeteria, but they are very cheap. Vegan dishes such as winter melon and fried radish are all one cents; leek, egg, garlic, pork with pork costs 2 cents; a chicken leg costs 3 cents, and a portion of fat pork is also three cents; rice costs 3 taels, and a large steamed bun costs 1 cents. Normally, 20 cents can be eaten for three meals a day. Of course, if you have a big appetite, you have to pay more.

Zhao Hao used seven cents to make two meat, one vegetable and one portion of rice, and found an empty seat to sit down and chatted with several workers next to him. During the three months of going out to sea, Mr. Zhao finally learned to put down his figure, go deep into the grassroots, and ask the people about their well-being.

But it is impossible to get along with the masses. After all, this is an era that emphasizes high and low rank. Just sitting at the same table with Mr. Zhao has already made several workers tremble and poked their chopsticks into their nostrils, let alone chatting with him.

If Ma Laohu hadn't warned him with his eyes, they would have run away with a wooden dining plate.

Mr. Zhao can’t just eat like this, right? That’s too funny. He could only continue chatting with others and ask where they were from? He was not satisfied with their meals and accommodations.

The workers were stuttering at first, but Mr. Zhao asked questions about family matters, and their answers gradually became smoother.

They told Zhao Hao that he earned a lot here, ate well, and had no problem with accommodation. The only problem was that the boat yard was on the island, so it was too inconvenient to go home. Most of them hadn't been home for a year.

Of course, in this era, those who go out to work are not during the New Year, but who can go home? So they just talk about it casually.

"Then move the house here." Mr. Zhao smiled and said, "Will you be able to go home every day? Isn't it so good to have a warm kang?"

"Then the relationship is good, but I can't get rid of the house." The workers were moved when they heard this, but then shook their heads and said, "Where are you here to stay?"

"This is simple. If you want to rent out the land for your own, you will not rent out the land for others." Zhao Hao smiled and said, "There is no shortage of land on Chongming Island. Go back and build a shipyard farm, it depends on how much you can grow in your family."

"The place to live is even simpler. Director Ma, he built a family courtyard outside the factory at the beginning of the year, which is specially provided to the workers' families." Zhao Hao first ordered Ma Hu. After he responded, he also said to Jin Xuezeng: "Your county should also support you. He shouted all day long to absorb the population and increase the population. With so many high-quality populations here, why are you indifferent?"

"Oh yes, why didn't the disciple expect it?" Jin Xuezeng quickly slapped his forehead and said with annoyance: "Let me go back and take out a charter to attract the workers in the shipyard, and all of them settle their homes on Chongming Island!"

"Haha, the county magistrate heard this? You stared at him behind his butt, don't let him lose his words." Zhao Hao smiled at Ma Hu.

"I dare not, don't dare." Ma Hu hurriedly smiled embarrassedly, and even if he had the courage to take Joe with his parents, he would not dare to take Joe.

The workers around then realized that the parents of a county came and were so scared that they knelt down and kowtowed to Jin Xuezeng.

"Get up!" Jin Xuezeng had no choice but to show off the dignity of his parents in a county, and encouraged everyone with a few words of warm voice, and welcomed them to bring their families to Chongming Island to settle down.

Now that the seawall has been repaired, he has the confidence to say this. If it were in the past, it would probably make people look like they were slap!

You have just come to this ghost place to settle down, your whole family has collapsed into the sea...

~~

After a while after lunch, Mr. Zhao came to Zuolang on the shore with everyone.

Zutang is a dry dock, which is also a very mature technology in the Song Dynasty. The major Zutangs in Longjiang Bao Shipyard left a deep impression on Zhao Hao.

The Jiangnan Shipyard is built on the shore of the silt and sand. It is not as good as the Longjiang Factory. It cannot directly connect the pond to the river, so it cannot be as simple as digging a hole on the shore.

The pond here is a semi-open rectangular structure. You must first dig deep troughs on the shore, then pour and reinforce the walls and bottom of the pond with bamboo gravel concrete, and then use concrete structures to extend the deep trough into the sea.

When workers build ships in the pond, they use the sluice gate at the end of the pond to block the sea water outside the pond. When the ship is completed and can be put into the water, they will remove the support and open the sluice gate. When the sea water injects into the pond, they can take the opportunity to drive the ship out.

The ships that need to enter the factory to repair must also enter the pond while the tide is high. Before the tide is low, temporary support should be provided to prevent the water level from falling and rolling. After the tide is low, the water gate falls and drains the water inside. Workers can go down the pond to strengthen the support, and then repair the ship and paint it.

At this time, the Oriental Beauty stood quietly in the pond No. 7, which was specially built for it. Dozens of logs support its huge hull, and the entire ship was all in the sky from top to bottom.

It was also the first time that Zhao Hao looked at this "Oriental Beauty". He saw that the hull under the water line was obviously wider than on the water. This round belly was the secret that the Garen ship could withstand the side volley.

"I didn't expect that I was still a pregnant beauty." After looking up and down for a while, he asked the Yang brothers standing beside him, "How is it? Do you have the confidence to copy it?"

Yang Mi hesitated for a moment and replied cautiously: "You have to understand this boat thoroughly before you can answer the young master."

"When can we understand it thoroughly?" Zhao Hao asked afterwards.

"The structure of this ship is much more complicated than our lucky ship, and I'm afraid I can't understand it for a while." Yang Mi said as she glanced at Yang Fan beside her and said, "If my brother could be together, the model should be built in a few months."

"Are you a ship model?" Zhao Hao's eyes lit up. He likes to play with ship model the most.

"Yes." Yang Fan nodded and said, "The first step in imitating the ship's model is to build a reduced ship model. Although the ship model looks like a child's toy, there is no shortage of components on the ship, and the internal and external structures are exactly the same, but they are all small in size."

"Yeah." Zhao Hao didn't feel offended at all, and still nodded with interest. "It's time to reduce the proportion."

"By building a ship model, you can clearly understand the components, structure, and construction order of the ship. So as long as you can build a ship model, we will be clear about how the ship should be built." Yang Fan said again: "And it can also replace a real ship to test the performance and defects of the ship model."
Chapter completed!
