Sui and Tang Dynasties: Killing Emperor Wen of the Sui Dynasty to sacrifice to heaven at the beginni

Chapter 581
As the saying goes, more people make things easier.

With more people, the strength is naturally greater. After gathering these [-] laborers, the construction of the entire project will increase at a speed visible to the naked eye.

After a few months, the overall structure of the shipyard has been built.Of the six docks planned, one has already been repaired.

Once you have a dock for the time being, you can start building ships.

Shipyard, inside the office.

"The deeper the keel, the deeper the draft. On the sea, the deeper the draft, the safer the boat!"

"Keel, the manufacturing process of the keel must be guaranteed!"

"A sea-going ship needs to use pine wood as its board and cypress wood as its bone. The cost of a ship is probably sky-high!"

Under Li Chun's leadership, these craftsmen from the Ministry of Industry began to discuss how the ship should be built.

Li Mu also raised some opinions from time to time among the people in the meeting.

Although craftsmen in the Sui Dynasty seldom built seagoing ships, they had never eaten pork, but they had seen pigs run away.

Sarina seldom builds sea boats, but they also know that sea boats are different from inland flat-bottomed boats.

There are strong winds and waves everywhere in the sea. If you use a flat-bottomed boat to sail, it means that the old birthday star has hanged himself and is impatient to live.

Therefore, if you want to start building a sea-going ship, the first difficulty you must overcome is the keel.

As long as the keel is designed well, the rest will be easy to handle.

It's not okay to hold meetings all the time and talk about military affairs on paper, and it can't solve any practical problems.Talking too much on paper cannot replace practice.

Under Li Mu's urging, Li Chun led the craftsmen under him to try to make it.

Now, one of the docks has been built, which can be used to make oaths.

At this time, while the shipyard was continuing to improve, Li Chun and the others also began to manufacture sea-going ships experimentally.

The sea ship that Li Mu wanted first was the huge treasure ship that Zheng He used during his voyages to the Western Seas. However, with the current craftsmanship of the Sui Dynasty, it is difficult to complete the manufacture of such a huge treasure ship.

After all, it is difficult to become a fat man by eating in one breath.Huge treasure ships could not be built, so Li Mu could only settle for the next best thing, ordering Li Chun and others to start building from the slightly smaller blessing ships.

Although the craftsmen of the Sui Dynasty were quite skilled, the maritime trade in the Sui and Tang Dynasties was not as developed as the Song and Ming dynasties.

He also has little knowledge of the sea, so he is not skilled in sea-going ship technology.So it's all about feeling the stones.

Relying on the current skills of the craftsmen of the Sui Dynasty, let them build treasure ships of more than 50 feet, that is, more than 150 meters, I am afraid that it is really difficult for them.

Therefore, we can only start building from these lucky boats that are more than ten feet long and four to fifty meters long.

For a large ship of 50 meters, this is not a problem for the boatmen of the Sui Dynasty.Because, the flagship ship of the Sui Navy is also about 50 meters long.They have built such a big ship, and now it is nothing more than a chaotic ship that has become a sea ship.

Moreover, from the perspective of the internal structure alone, the internal structure of the Sui Army's navy ships is much more complicated than the sea ships they built.

Navy building ships need to build places to hide soldiers, towers, etc. inside.But Fuchuan does not need to be so complicated. It is enough to build a large warehouse and a simple residence.

These craftsmen of the Ministry of Industry can start with the lucky boats of more than ten feet to practice making sea boats.After the lucky boat is proficient in manufacturing, it can gradually increase the size of the ship, from a dozen feet, to twenty feet, thirty feet, and finally to a giant treasure ship of fifty feet.

It is still in the Sui and Tang Dynasties, as long as a huge treasure ship can be built in the past few years, or even more than ten years, then it is enough for the Sui Dynasty to travel all over the world.

After about two more months, the first lucky boat was finally repaired in sevens and eighties, and after a few days of perfection, it was recorded and launched for sea trial.

The length of this blessing boat is about thirteen feet, and the width is about five feet. If converted into the measurement units of later generations, it is about forty meters long and 15 meters wide.

This lucky boat has four floors, the bottom floor is a warehouse, the middle two floors are used for living, and the top floor is a simple tower.

Fu Chuan is a sea ship, which is different from an inland ship.Sea ships have no oars, and all power comes from wind and waves.

In front of the sea, manpower is insignificant and not worth mentioning.Therefore, when sailing on the sea, you can only raise the sails with the wind and lower the sails with the wind.

Even if the sea boat is equipped with oars and wants to sail against the wind, even if the Hulk comes, he can't shake the oars.

To put it simply, sailing on the sea does not require oars, but relies entirely on waves.

In the era before the invention of the internal combustion engine or the steam engine, all the power of sea ships was to rely on sails.

There are three sails on this lucky boat. In the middle of the hull is a big sail. The function of this big sail is to provide power for the hull.

In addition to the big sail, there are also small sails at the bow and stern of the blessing boat.

The function of these two small sails is not to provide power, but to adjust the direction and turn around.

These three sails are all made of tanned cowhide, which can effectively prevent the erosion of the sea.

The deck of the fuchuan is very flat, and the head and tail are sharp knife-shaped, which are used to chop the waves.The bottom of the ship is a deep keel, and the draft is very deep, which can ensure the stability of the hull during sailing.

Whether the car is good or not depends on the three major parts, and whether the boat is good or not, it depends on the keel.

The keel of Fu Chuan is an inverted triangle. As we all know, the stability of a triangle is the strongest, and the stability of this inverted triangle is even stronger.

The inverted triangular keel made of strong cypress can withstand the huge twisting force of seawater while being able to bear huge weight.

Li Mu looked around the hull for a long time, and found that the ship was really well built.That's right, after all, these craftsmen have experience in making dragon boats for Yang Guang.

Compared with Yang Guang's dragon boat, the craftsmanship of this lucky boat is actually nothing.

What these craftsmen have to do is to correct the thinking of making inland ships and study what sea ships need.

In terms of this technology, there is no problem with the craftsmen of the Sui Dynasty, it is just that their thinking needs to be corrected.

After the first ship was manufactured, these craftsmen actually realized a lot in their hearts.After having this first manufacturing experience, they also understood what sea ships need.

"Not bad!"

"It's pretty good. I don't know when we will be able to build a ship of more than [-] feet?" Li Mu asked Li Chun.

Everything is difficult at the beginning. After the first sea-going ship was built, the difficulty of making sea-going ships gradually increased.
