Anjiang Shipyard has launched two types of all-wood sailing boats: Taiwan-class rigid sailing boats and Taiwan-class soft sailing boats.

The model of the sailing ship he built two times proved to be inapplicable in the actual test, not to mention the manpower required to operate it, and the process was troublesome and quite dangerous.

After reading the materials handed over to him by Director Wu Jie, Chairman Wu Dapeng asked curiously: "Director Wu, isn't there a dispute between the two parties?" Didn't you watch them argue? ”

"I saw the records later, but they didn't seem to be right—"

"Fake fans!" Wu Dapeng shouted excitedly and said, "I said, only pseudo-fans are the most noisy!" ”

Director Wu Jie smiled generously.

Chairman Wu Dapeng snorted and said, "I've tired you these days, let's go take a shower together, and I'll rub your back!" ”

In the bathhouse, Director Wu Jie soaked comfortably in the hot water and said: "First of all, there are indeed two types of sails, crosssails and longitudinal sails.

The Chinese-style hard sail is a sylon sail because it can rotate with the wind, so it can sail regardless of downwind and upwind.

Western-style soft sails are divided into crosssails and sylvestithlers, and its sails are fixed, and the sails are not officially available until 1700. ”

"I understood it at once, come, Lao Wu, I'll rub your back."

Lying on the bed, Director Wu Jie said: "The merchant ships of the East India Company that we have seized are all sailing ships, and it is not easy for unknown sailors to control them. ”

"Old Wu, it's not easy for us, you raise your gods for a while, don't talk about it."

Director Wu Jie fell asleep after a while, and Chairman Wu Dapeng's movements were lighter.

The Taiwan-class Chinese schooner has a total length of more than 30 meters and a width of about 6 meters. The full load draft is 2.8 meters, the displacement is about 250 tons, the design load is 170 tons, the bottom of the ship is densely covered with ribs and divided into nine watertight compartments, the bottom bilge is ballast with cast iron scrap, there are twin masts, the main mast is 21 meters high and the foremast is 16 meters high, the main and auxiliary sails are all Daming style flat-topped high sails, and the huge main sail with the slats on the sail surface is 2.8 tons; the suspended tail rudder ensures safety in shallow water; its freeboard is about 1 meter high, and it can even carry 300 tons of sailing in a breezy weather.

The ship fully borrowed from the North American fast sailing boats, and took into account the climate of Fujian and Taiwan, where the wind direction is changeable and the strength is uncertain, and the Chinese sail installation has obvious advantages, and the whole ship needs a total of 21 crew members.

On the coast of the Ming Continent, the Fu ship and the Guangzhou ship are the famous pointed bottom ships in the deep-water routes of the South Seas, they are all on the basis of the past flat-bottomed ships, after the transitional changes of the hull structure rebuilt, and the two upturned ship types with keels in Europe in the same period are completely different, the bottom of these two ships is particularly sharp, swinging faster at sea, but not easy to sink, most of its rudder materials are made of iron wood, which is strong in the waves, and it is not easy to break, which is very important in sea navigation.

At this time, seagoing vessels generally adopt perforated rudder technology, which not only reduces the rudder shaft torque, but also improves the steering efficiency.

Since the Song Dynasty, there have been many improvements in the equipment of sea ships, the most important of which is the application of the compass.

The compass helped the navigator to find the right direction when the weather was dark, and the Ming continent was a world leader in navigation, and the rudder technology was also innovative.

For example, many holes are cut in the rudder blades to reduce the resistance of the water, and do not underestimate this little improvement, which was not adopted until the 20th century in the West.

In fact, when Anjiang Shipyard designed the Taiwan-class Chinese schooner, it absorbed the advantages of these two types of ships and made improvements in some key areas.

This is fully reflected in the ship model, and it also comes up with a detailed test number, leaving the people who have been arguing on the Internet speechless.

There must be better, this is nonsense, but, at the moment it is the most suitable, if you are not convinced, please see the number jù.

Counting jù is one of the best ways to resolve an argument.

In this ship model, the two first used CAD modeling technology to make the design and construction of the hull more in line with the streamlined body. Then on the outside of the hull, the seam is soaked in hemp silk with wood asphalt and tung oil, which is tighter than in the past when only tung oil and lime are used to fill the seam, and it is more resistant to sea borers, and the inside is made of celluloid seam, which is far better than the method of the ancients; In the place where the Daming sail is retracted, the fixed pulley block technology is redesigned.

In fact, I originally wanted to use small steam power to replace it, but later Director Wu Jie and Fan Xiu Technology calculated that they did save four sailors who lifted sails, but this is different from the sailboat, people originally had steam engine equipment, if they install it now, the volume and weight of the extra equipment and fuel will be greater than six people......

In the end, they determined that without more than 750 tons of deadweight tonnage, the equipment of the steam engine was not cost-effective; Then the long rudder was changed to a mechanical transmission control of the rudder, and at the same time, the rudder and the captain's room were combined to place, and a large celluloid window was installed to protect it from wind and rain......

The Taiwanese-class Western-style schooner has a waterline of 25 meters in length, 5.6 meters in width, 2.6 meters in depth, and a deadweight of 200 tons. The crew on board is limited to seventeen people.

In fact, the two of them directly took out the 1851 version of the "Baltimore Schooner" without the slightest change. Because this type of ship has undergone countless tests, it has been stored for up to a hundred years.

It has a long protruding head and stern post, which increases the effective length of the deck, and the keel has a tendency to tilt down to the tail to obtain a larger tail draft, which not only improves the longitudinal stability and speed of the ship, but also makes the transverse hydrodynamic center of the underwater hull move back greatly, so as to better balance with the sail pressure center, which is conducive to wind riding and reducing drift.

Its cross-section is V-shaped in the ship, which is very different from the U-shaped cross-section used in the previous merchant ships, the ship is also slenderer than the general commercial sailboat, the length-to-width ratio is about 5:1, the ship uses a flat deck, there is no superstructure on the ship, its appearance is low and long, and the bow and stern line is beautiful, which is conducive to reducing drag, facilitating sail and wind, and increasing the speed of the ship.

The boat did not have a hind cable, and the mast was tilted back to balance the sail thrust.

Then, Director Wu Jie and technician Fan Xiu tried to make a little improvement on the mast, adding a suspended jib spinnaker.

After repeated deductions, the duo found that this work well and further improved the sailing performance.

In the end, the Anjiang shipyard finally finalized the two ship types.

There is a reason why Director Wu Jie and Technician Fan Xiu determined the tonnage of about 200 for the two ship types, and the two fully considered the logging, transportation and processing capacity of Hantang Group during this period.

Of course, the technological capacity of shipbuilding is the first consideration...... This time, the manufacture of all-wooden sailboats is based on Akito craftsmen as the main technical force, and to be honest, the two of them are always vaguely worried...... For the first two ships, the tonnage is still a little smaller.

Shipbuilding requires a large number of giant trees, and those that can be used as ship timber are "not hundreds of years old wood, not medium-range".

For example, the average growth cycle of a mast tree is 60 years, compared to 80 years in Fujian. At the end of the Ming Dynasty, the Zheng Group was able to build a large number of ships at sea for decades, mainly because the eastern coast of Fujian could obtain timber from the mountainous areas of northern Fujian.

At this time, there were also more suitable large trees in Taiwan, which was close at hand, but the armed forces of only a few hundred people in the city of Geranza, a branch of the East India Company, the Dayuan Merchant House, could block the eyes of all the shipyards in southern Fujian at that time...... Everyone ignores Taiwan's abundant timber resources...... It really makes the people of the Hantang Group despised, but they can only accept these people...... They are our ancestors......

In the history of that world, at the end of the 17th century, in order to pacify Taiwan, the so-called Qing government also began to build a large number of warships in Fujian. At that time, it seemed that Shi Lang was in charge of shipbuilding.

This shipbuilding competition between the Qing Dynasty and the Zheng Dynasty consumed excessive shipbuilding giant timber along the Yangtze River, which made the shipbuilding materials very scarce after the opening of the sea much later.

On the one hand, timber resources are tight, and on the other hand, a new round of shipbuilding activities requires more timber supply, and as a result, the price of wood and ship prices rise at the same time.

At the beginning of the Qing Dynasty, the value of a large tree in Fujian was not more than a few taels; During the Qianlong period, the mast wood in Fujian had risen to four or five hundred gold per piece.

According to records, during the Kangxi period, foreign ships were built, but each only needed thousands or more than a thousand gold.

During the Yongzheng period, a foreign ship was built in the mainland, the big one was seven or eight thousand gold, and the small one was two or three thousand gold. In the first half of the eighteenth century, the average cost of a foreign ship was about 5,000 taels of silver, and by the nineteenth century, it was tens of thousands of gold for building a large ship.

Of course, in addition to the fact that there is less and less wood available for shipbuilding, this higher and higher price is also related to the fact that the ship type is getting bigger and bigger.

Director Wu Jie and technician Fan Xiu didn't care about these price issues, but they were more interested in the other depictions in this information.

At the end of the Ming Dynasty, the shipowners who returned from selling goods in Nanyang brought exciting news to some shipyards in southern Fujian.

During the voyage, they saw that the Siamese country was 2,400 miles long from the mouth of the sea to the national city, and the banks were lined with large trees and forests, and the wood was solid and suitable for ships.

Especially in the Quang Nam area, a kind of mast and salt rudder wood that is eight zhang long and has no knots are produced.

In the Luzon Islands, there are about 4,200 species of trees, about 50 zhang high, which is convenient for building boats and houses, and the island is particularly rich in ironwood.

On the north shore of Borneo, there are also a lot of pine trees, which can be used as large masts, all of which delight the Ming merchants.

In fact, during this period, because the Ming government believed that its country was very distinctive, and it strictly controlled the private shipbuilding industry, some maritime merchants who had strength in the Ming Dynasty put their shipbuilding business outside the Ming Dynasty...... This is much better, and the Ming government can't even collect a dime in taxes.

During this period, no matter how the Ming government tossed in the wind and rain, the overseas shipbuilding activities of these maritime merchants did not stop.

This phenomenon can even happen. When some ships of the Ming maritime merchants set off from various places in Guangdong and Fujian, they carried their own craftsmen and other technicians on board and sailed in the direction of Siam. These technicians know merchant ships inside and out, and in the event of a shipwreck, the ship's personnel can repair them themselves or prepare the ship immediately.

On their way to Siam, they cut timber along the coast of Vietnam, bought some more when they arrived in Bangkok, and built a sailboat directly from the wood, and within two months they had a sea-going boat – all the sails, ropes, anchors and other work made by hand. ”

Materials such as oil, hemp, oyster ash and nail iron needed in shipbuilding are generally shipped out of the country together.

Later, after the establishment of the Qing Dynasty and their ban on the export of ironware, a large amount of ironware could still be smuggled overseas.

Later, since the third year of Yongzheng, the Qing government allowed ships to carry a certain amount of iron nails, putty, silk, jute and other materials for repairing ships.

This should be a good opportunity to obtain ship materials from overseas. Oyster ash for shipbuilding, because of the coastal waters of Southeast Asia, should not be difficult to solve. As for iron nails, they can also be made in Southeast Asia.

…… Some of the Ming craftsmen who had previously emigrated to Penang, Malacca and Singapore also made a large number of hardware products such as hoes, nails, axes, chains, etc.

In Southeast Asia, the restrictions on shipbuilding are too relaxed, and most of the ships built are large ships, with a carrying capacity of between 7,000 and 10,000 stones, which is about 400 to 600 tons, and the cost of shipbuilding in the local area is only half of that in China.

Akito's talent was on full display overseas.

The Anjiang shipyard needed them to showcase their talents in Taiwan as well.

After comprehensive consideration, Director Wu Jie and Fan Xiu technician officially put forward the requirements for the introduction of shipbuilding technical workers on the Internet.

This request was approved immediately, and because the required personnel were specifically implemented in this request, when this request was sent to Guangzhou and Xiamen, the people there quickly recruited Ming technicians like taking medicine according to a prescription, and soon sent it to the Anjiang shipyard.

Director Wu Jie said: "If these two ships are officially completed and can complete the sea trials, it will mark the official establishment of our shipyard......

Fan Xiu technician said, "What about the flying clippers?" Do you really let those enthusiasts get their hands dirty? ”

"Why not? Do-it-yourself and get enough food and clothing...... Save them a day of chattering on the Internet...... If it doesn't work, we can still help, and if it doesn't, there are Akito technicians, fuck, Akito craftsmen are better than us, at least they have built all-wooden boats of more than 100 tons. ”

"Are you alright? We have CNC woodworking machine tools ......"

Thank you for the support of our friends at the beginning, mabol.
