In the Quanzhou Port Shipyard, at this time the shipyard is starting to build the first sea vessels, a total of two sea ships, will be built at the same time. Pen "Fun" Pavilion www.biquge.info

A fortune ship, that is, Zheng He's treasure ship, has a total length of more than 140 meters and a width of 60 meters.

This built ship has four floors, nine masts on the ship can hang twelve sails, and one anchor alone costs several thousand catties, and it takes at least two to three hundred people to operate a ship.

Li Mu also knew that the draft of this lucky ship under construction would exceed six meters.

Next to the Fuku, a seagoing ship that was also under construction, was a much smaller clipper ship, built on the template of the American Grand Republic.

It is no more than 100 meters long, 17 meters wide, 9 meters deep, has a displacement of 3,400 tons, and the main mast is 61 meters high.

This clipper is like a teenager to the lucky ship next to it, but the clipper is extremely fast, and his clipper style makes it sail at sea at the speed of a wooden sailboat.

Although the flying shear ship has a hull of less than 100 meters, it can be regarded as a big ship compared to the ships of the Tang Dynasty.

"Master, is this the Fortune Boat and the Flying Clippers?" Mei'er, who accompanied Li Mu to see the construction of the sea ship, pointed to the keel of the sea ship being built and asked.

"Well, that's the Fortune Boat and the Clipper Boat." Li Mu nodded, and after speaking, he looked at the craftsman who was building the keels of the two sea ships.

"Then why did they build the skeleton? Is this any different from a building ship? Mei'er was a little puzzled, looking at the keel of the sea ship being built, which was very different from the building ship she knew.

The Fuchuan looks somewhat similar, after all, the bottom of the Fufu boat is flat, and the bottom of the building boat sailing on the rivers and lakes is the same.

In order to pursue speed, the clipper ship is not only slender, but also the bottom of the hull is also the pointed bottom of the modern sea ship, in order to break the water surface well, reduce the resistance of the water, and increase the speed of the ship.

Coupled with the keel that Meier has never seen before, there will inevitably be some doubts.

"This is the difference between the sea ship and the building ship, only the ship built in this way can safely sail on the sea, and the building ship, when it goes to the sea, it is estimated that it will collapse soon." Li Mu replied simply.

Both the Fu boat and the clipper ship are built with a full-body keel, so that the wooden sailing ship will be more stable when sailing on the sea, and can better protect the safety of the personnel on board.

"Oh, I still don't understand." After listening to Li Mu's words, Mei'er tilted her head, she only felt that the sea ship under construction in front of her must be very big, but it was not as big as the Muhai.

"Okay, let's go back, it's easy to catch a cold when the sea breeze blows here." It was rare to see such a cute side of Mei'er, Li Mu smiled and touched Mei'er's hair, and saw that Mei'er was wearing a gauze skirt, under the action of the sea breeze, blowing the skirt to a chilling sound.

"Hmm." was killed by Li Mu's touching of the head, Mei'er became even weaker, and she lost her courage and heroism in the face of others.

After Li Mu finished watching the construction of the sea boat, he took Mei'er back to the camp.

As for the construction of the sea ship, it is natural that there will be people below to supervise it at any time, unless something will disturb Li Mu's rare moment of peace.

This may be the benefit of the elite class, as long as you give an order, someone will naturally do it for you, and you just need to sit back and enjoy its achievements.

....

Thanks to the assembly line operation introduced by Li Mu, the shipyard was divided into three shifts, and three shifts were carried out every day, and the entire shipyard was working day and night.

In addition, the construction size of each Fu ship and clipper ship, Li Mu has already unified it with the shipbuilders in advance.

All the Fu Ship and the Clipper Ship are of the same size, the same design, and will not make any major changes to the hull, and the changes will only be made after the construction of the sea ship will be made minor internal modifications.

In this way, since the size of the Fu ship and the clipper ship had been determined in advance, there would be no change, so Li Mu asked the craftsmen to divide the two types of sea boats, and then subdivide and number them according to each section of the hull parts.

Each part that has been numbered is subdivided, the size of the size is strictly refined, and the data of these parts is presented on the drawing.

In this way, the craftsmen can use the electric tools brought by Li Mu according to the drawings and start to manufacture the parts and components needed for the sea ship in large quantities.

This is the mold proposed by Li Mu, such an advantage is that when the ship is repaired in the future, the broken part can be replaced according to the drawings.

Another point is that in this way, the mold can produce parts for the construction of sea ships in an assembly line, so that the speed of building sea ships can be accelerated.

If there were no three-shift, assembly-line, and mold-based construction of sea ships in the past, it would take a year to build a Fu ship using crowd tactics in the case of a Fu ship.

Then, after having these three common methods in modern industrial production, plus the tactics of crowds, it will take three months to build a lucky ship without skill.

It takes a month to build a clipper.

Then, after the craftsmen who built the sea ship were skilled, the construction period could be shortened again, and the construction time of the Fukufu ship could be shortened to only two months.

The construction time of the clipper ship is 20 days.

When the Quanzhou sailors surrounded and suppressed pirates, captured strong men, and then carried out brutal training to expand the sailors, the shipyard also built sea ships in three shifts day and night.

Li Mu, who came down in his spare time, did not completely stop his steps.

At this time, he had already set his sights on the matter after the construction of the sea ship was completed and the Quanzhou Navy Division was expanded.

After the Quanzhou Navy Division took over the first batch of clippers and really formed a fleet, Li Mu needed to equip this fleet with weapons.

And Li Mu didn't want the Quanzhou Sailor to be like other Tang Sailors, so he wanted to prepare something special for the Quanzhou Sailor.

The things prepared by Li Mu are just ordinary things for modern times, but in the Tang Dynasty, only Taoist priests will occasionally refine some for consumption.

That's right, black powder, a kind of gunpowder made with sulfur saltpeter charcoal, stir-fried.

In addition to the cold weapons brought to him from modern times, Li Mu also wanted to make large quantities of black powder in Datang.

Although this kind of gunpowder is very ordinary in modern times, it has been reduced to gunpowder used by ordinary people to play fireworks, for modern people, black powder is already a very low-grade gunpowder.

However, black powder still occupies an important position in Datang, and the current Quanzhou Navy Division also needs this gunpowder to increase combat effectiveness.

With black powder, the Quanzhou sailors will be like a tiger with wings on the sea or on land.

In the following days, Li Mu asked Mufeng to buy a large amount of saltpeter and sulfur in Datang and transported them to Mawei Port in Quanzhou, and charcoal could be made locally in Quanzhou.

Time flies!

(Warm reminder to book friends, don't try to fry black powder in reality, because if the police uncle finds out, he will be arrested and imprisoned.) ）
