Chapter 73 Black Ship (first update, please recommend, please collect)
The man of One Piece needs to have a sea ship first.
When Yan Ruxue came to the saltworks, she brought Fang Dayang's message that the ship was almost finished.
The boat is almost finished!
After getting the news, Shi Yiwen hurried back to the stockade in the early morning of the next day. He didn't even wash his face, and went directly to the shipyard because of his ship. To be called a shipyard.
Guo Huaiyi followed him as a matter of course. As soon as he entered the shipyard, Fang Dayang greeted him happily and said.
"Master, you see, our boat is basically finished now, as long as the seams are finished and a layer of tung oil is applied, the boat can be launched."
Seams are a necessary craft for wooden boats. Specialized craftsmen use tools to fill hemp threads into wood gaps, tamp them, and then apply tung putty on the gaps, and use tools to scrape the sealing surface and remove excess. putty.After completing this procedure, the boat can be launched.
This process was an indispensable process for building wooden boats in the 17th century, and it is also the same in the 21st century, except that the hemp silk has become a synthetic fiber.
"Well, I see!"
Nodding his head, Shi Yiwen looked at the sailboat that was almost completed. On the legs on both sides of the hull, there were dozens of craftsmen standing, filling the hemp silk bit by bit. Press the chisel tightly, otherwise the hemp thread chiseled into the gap will be of different thickness, and there is a possibility of leakage in the water.
After this process is completed, the ship will be completed!
"This, this is the ship you built?"
Guo Huai said in surprise.
"Correct."
"He's a sloop,"
"What happened to the sloop?"
"How can a sloop go out to sea?"
Guo Huaiyi's rhetorical question made Shi Yiwen laugh out loud.
"Why can't a single-masted ship go out to sea, don't worry, this ship is not a problem in the offshore, even crossing the ocean is no problem, and its speed is faster."
In the age of great voyages, I don’t know how many pirate captains crossed the Atlantic Ocean with such a Sroop ship not much bigger than a fishing boat, circumvented the Cape of Good Hope, and tried their luck in the Indian Ocean and the Pacific Ocean.Most of the time, they sail thousands of kilometers without encountering suitable ports or sheltered harbors. Some of these voyages are not much worse than the epic journeys of the most famous navigators.
For such a small boat, the seaworthiness is absolutely first-class, and the load capacity is also extremely good.
When walking towards the boat, Shi Yiwen said while walking.
"By the way, Dayang, last time I asked you to tell you that you used asphalt for the caulking, and you used asphalt, right?"
Tung putty was used for shipbuilding seams in ancient China. After solidification and hardening, tung putty will fall off when it collides. Compared with asphalt, it is more suitable. However, the source of asphalt in ancient China is limited. Although the source of petroleum asphalt is limited, there is a similar Product - Asphalt, also known as wood pitch, is a by-product of burning charcoal and is the same as wood tar.The scope of application is also very wide.The term asphalt has even influenced later generations, and even until the 21st century, many people still call asphalt roads as asphalt roads.
"It's ready, it's worth a thousand catties, master, those asphalt caulks are good, and they are elastic after drying, but we don't need that much. Those things are really not cheap."
"I have other great uses."
Shi Yiwen pretended to be mysterious and said.
"Master, is it painted on the boat? A black boat like Hongmaofan?"
Black Ships - European ships of this era were called black ships because they were tarred.
"more or less,"
Shi Yiwen still didn't explain.
In fact, he did this on purpose. After all, sometimes some things inevitably need to be kept secret. Using asphalt caulking is nothing worth keeping secret. European shipbuilding in this era is all using this process.
But he had to keep secret about another use of asphalt.Because it is related to a core technology.
The main resistance of the ship when sailing is the friction caused by the rough surface of the hull, and the marine life attached to the hull seriously drags down the speed of the ship.Although the ancients did not understand these scientific principles, they also understood that large ocean-going warships and merchant ships needed regular hull cleaning to maintain their speed.
When sailing in the tropics, the warm waters also harbor scary creatures called "shipworms."Like a shield machine, shipworms will drill into the wood of the hull of the sailboat bottom, and within a year, the hull plates of the bottom of the boat will become honeycombed.To deal with the threat of these epiphytic and burrowing organisms, the bottom of the ship would have to be painted with some sort of protective coating, just like ships do today.
In this era, the most popular method was to use "black material", that is, a mixture of pine gum and tar to coat the bottom of the ship, but it was used for a year at most, and the surface was overgrown with marine life, which was broken by shipworms.This requires scraping off the original coating and applying a new coating.Repeatedly, such a protective coating is always unsatisfactory.
In the late 18th century, the British found a solution once and for all—their warships were covered with a layer of copper on the bottom of the ship. The copper skin has a good underwater resistance to epiphysis and decay.In this way, the problem of ship worms eating into the ship's plank was solved, but the cost was a bit too high. After all, copper is a precious metal in this era. It takes a lot of copper to cover the bottom of the ship, and most people really don't need it. Needless to say, what's more important is that the copper skin needs a rolling mill, which is obviously not what Shi Yiwen can provide.
But he has another cheat - science, science solves everything.In the 18th century, the British did not know why the copper skin had the function of resisting epiphysis and corrosion under water, but 100 years later, scientists discovered the reason—copper ions produced after copper was corroded by seawater were easily catalyzed Superoxide, these substances can effectively kill organisms.After this discovery, "three-proof paint" for wooden boats that can prevent fouling, corrosion, and maggots soon appeared. This kind of paint that replaces the copper skin is actually based on asphalt-based paints, copper poisons, pigments, etc. Several main components make up the paint, and the so-called copper poison can be either the original copper powder, low-carbon copper, or copper oxide.
The simplest and most primitive way is to add asphalt to copper powder.This technology is simple, but it can replace expensive copper skins, and like copper skins, it can increase the speed of ships.All it takes is a few handfuls of copper powder...
That's the power of science.
That night, under Shi Yiwen's instructions, more than a dozen students used wood tar, tar and copper powder to prepare the most primitive wooden boat "three-proof paint" of this era. The next day, when the craftsmen put the black bottom When Qiqi was on the boat, they didn't know that these black paints were special, at most they just said something in their hearts - just like Fanren's boats, they were all black boats.
