[This chapter draws on some professional introductions of the cat jumping god, so I would like to explain it here!]

"That's right!" Liu Jin replied with a nod.

"Since that's right, then ask the owner to announce the results of the game!" Jiang Liu looked at the sky and said proudly.

Hearing this, Xu Chen glanced at him, and Liu Jin also glanced at him, then turned his head away and ignored it.

As for the rest of the people, Lu Hao and the others were silent, Chai Lao was just a guard, and the guys behind Liu Jin had already seen the boat built by the shopkeeper, and they couldn't feel any turmoil in their hearts, so they naturally didn't jump out to hold grievances for their own boss, but let the boatmen who were waiting to ridicule each other on the opposite side be at a loss for a while.

The field was quiet, and Jiang Liu saw that the expected effect had not been achieved, so he could only finish it by himself. At first, he laughed "haha", and then said to himself: "Alas! Look at my memory, I almost forgot, Shopkeeper Liu hasn't appeared yet! Haha, don't worry! Boss, let's let Shopkeeper Liu try it first, and then announce the results!"

From beginning to end, only Jiang Liu was performing, and there was not even a single person on the field who answered.

"Hmph, load it for Lao Tzu! Wait until your broken boat comes out, and it's up to you to load it up again!" Jiang Liu thought fiercely in his heart.

"Lao Liu, it's your turn!" Xu Chen called.

Liu Jin bowed slightly, and then waved his hand to the guy behind him, it was also a conch, but the sound of the blow was slightly different, this method of transmitting information through guò was learned from the fishermen on the beach.

A moment later, a dark shadow sailed out from the west side of the island. The white boat and white sail, but the huge figure cut off the sunlight, which is quite like covering the sky and the sun.

On the long mast, the white sail is blown round, and the huge power is transmitted to the streamlined hull through the mast; the freeboard is low, and the less superstructure makes the ship have excellent stability, and at the same time, the low center of gravity makes it easy for the mast height to reach three-quarters of the length of the hull, and the sail area is particularly large.

The bow is sharp, sticking out like a shark's head, with a slightly concave surface that lifts up to split the waves, and a narrowing waterline at the rear of the ship that harmoniously transitions to a narrow round tail, which together with the bow and the middle of the hull form a minimum drag.

Along the bow of the ship, a mast is stretched out in the direction of the direction directly in front of the ship, and four sail ropes are pulled up between the mast and the foremast, and a spinnaker is hung; the foremast, mainmast, and aftermast are hung with full sails, and the width of the sail greatly exceeds the width of the hull, and the transverse mast extends beyond the hull, and each mast uses the mainsail, the top mast and other large and small square sails, as well as the support sails, wing sails, and other triangular sails. The complete set of sails is able to accept the wind blowing in all directions, and unlike the complex canopy ceiling cables of some of the larger European sailboats, the cables of these sails have been optimised to handle up to twenty sailors.

Yes, this is the pinnacle of human exploitation of sailboats in history...... The flying clipper sailboat, so named after its hollow bow that cleaves the waves, is widely believed to have reached the limit of a large sailing ship at thirteen knots per hour.

This type of ship was supposed to appear only in the middle of the XIX century, but now, it was born more than a thousand years earlier.

"It's finally made!" Seeing this pinnacle in the history of sailing really appear in front of his eyes, Xu Chen couldn't help himself and was excited.

The "Great Republic" built by the United States in 1853 is 93 meters long, 16.2 meters wide, 9.1 meters deep, with a displacement of 3,400 tons, a mainmast height of 61 meters, a full sail area of 3,760 square meters, a speed of 12~14 nautical miles per hour, and only 13 days to cross the Atlantic.

The ship in front of Xu Chen is an imitation of the "Great Republic", about 30 zhang long, more than 5 zhang wide, the distance from the keel line perpendicular to the deck is a total of three zhang, the main mast is about 20 zhang high, and the sail area is not much different from the original.

But to say that it is a scissor sailing yacht with pure blood, it seems unfair. Many ancient Chinese shipbuilding techniques are embodied in it:

China was six centuries ahead of Europe in watertight compartments. The ship is divided into seven compartments, and if one of them is flooded, the ship can continue sailing, if two compartments are flooded, the ship can drain and save itself, and even if the luck is at worst, more compartments will be flooded, which will slow down the sinking of the ship and give the crew enough time to escape.

Invented during the Northern Song Dynasty, the retractable balance rudder was not used in England until around the nineteenth century. When the wind direction is stable and the rudder is sailing for long distances, the rudder plate is raised without underwater resistance, and when you need to turn quickly, the rudder pressure center of the balance rudder is small and the distance from the rudder axis is small, so the rudder torque is small, and the course can be controlled very easily. Such rudders can not only adapt to ocean navigation, but also be flexible and comfortable in the complex sea conditions of high winds and waves.

The ropes and pulleys worn in large bamboo tubes allow the captain to stand in the bow with an open line of sight and turn the rudder plate to control the rudder plate at the stern.

As the most superior wind-powered boat, the flying clipper sailing boat has risen rapidly and declined suddenly, making its short and glorious life sigh to many sailing enthusiasts. For this reason, although in the era of gas-fired engine ships, there are still many enthusiasts or environmental enthusiasts who put the design drawings of the scissor sailboat on the Internet to discuss, and at the same time constantly make improvements, and many well-funded local tycoons have taken the initiative to design and build sailboats that can be used for sailing.

For this reason, it was not difficult for Xu Chen to get such a detailed drawing, but the difficulty was to memorize the things in his memory again. Since coming to this era, Xu Chen has always had a sense of crisis, and for this reason, he naturally attaches the most importance to sharp weapons such as flying scissor sailboats.

After racking his brains, he finally repeated the rough drawings, but there were many ambiguities in the details, so Xu Chen had to hire the old shipwright of Hongzhou Shipyard as a consultant while thinking about it himself. Fortunately, Xu Chen only knocked on the side every time, so he was not noticed by the Wan family.

There is still a lot to do, from the blueprint to the launching of the ship.

Water wheels, circular sawing machines, pulley sets, sewing machines, lathes, it is not difficult to achieve these.

In the eighth century B.C., pulleys appeared in China, in the fifth century B.C., there were forty-tooth bronze ratchets in China, and soon after, iron ratchets appeared, and in the Han Dynasty B.C., China had the technology to process steel down to the millimeter, which could be further improved if craftsmen were given enough time to grind by hand...... It can even be said that craftsmen can build their own machines by simply coming up with ideas and sketches, and the machine tools used for woodworking have very low precision and strength requirements.

Only the sewing machine is more complicated, fortunately only the thick needle is used to sew the sail, the components do not need to be so fine, the simpler the structure, the better, as long as it can be used. The designed pedals transmit power to the fuselage through a guò belt, and the eccentric wheel converts the rotational motion into reciprocating motion, so that the needle can be pricked up and down.

In addition to tools, the form of organization of production is also an important factor in determining labor productivity. In the Qin Dynasty, the arms manufacturing industry realized assembly line operations, and the Chinese shipbuilding industry achieved professional subdivision at least when Sun Quan built the sea ship "Chang'an", but I don't know why, maybe it was the devastation of the war or the loss of written records, but there was no assembly line operation in the handicraft industry of later generations.

But this qiē is not a problem for Xu Chen, an "outsider"! As soon as the specialized public loft is built, the guys who have been trained for several months in advance will be able to get started quickly, and the production efficiency will naturally be greatly improved.

In addition, the benign competition mechanism and the wages and remuneration for more work have fully mobilized the enthusiasm of the workers, and more than 500 people have worked tirelessly for ten days to finally build this fantastic sailing ship.

Of course, in this competition, Xu Chen did open a small stove for Liu Jin, and the required parts had already gone through a lot of processes before, so that Liu Jin could build the sailboat in just ten days.

As soon as this boat came out, Jiang Liu was really as Shi Lei said first, and he was shocked on the spot!

Although Jiang Liu's temperament has become extreme, but the ability is still there, Zhenzhen only glanced at it, and saw the superiority of this ship, after all, there are always many similarities between the same craftsmanship, and under the bypass, some basic appreciation ability is still there.

Just looking at the size of this ship, it can be seen, after all, just like Jiang Liu himself said, shipbuilding is not simply a few wooden planks grafted together, to be able to build a ship of this size, without some skills can never be done!

But that's all, Jiang Liu will not bow down and admit defeat!

"Quick! Try it!" At this moment, Xu Chen has already put aside the competition in his heart, and now that the sailboat has come out, if the performance is not much different from the original after the test, then with this Xu Chen, his own strength will get a qualitative leap!

"Okay!" Liu Jin smiled and nodded, and then gave the order to start the sailboat.

I saw that the white sailboat was like a dexterous dolphin, just a slight sideways, not much movement, the hull made a 90-degree turn, the speed is extremely fast!

The sound of the snail sounded, and the flying scissor sailboat broke through the waves, and disappeared in a moment, worthy of its name of "flying".

Just an hour later, the sailboat reappeared.

"Report! Master Jiang's boat goes back and forth for two and a half hours, and the speed of the ship is eighty miles and one hour, and the boat of Shopkeeper Liu goes back and forth for exactly one hour, and the speed of the ship is two hundred miles and one hour!" A young man who specialized in statistics came to Xu Chen with a booklet in his hand and announced loudly.

"Okay, good! Sure enough, we can reach this speed!Haha! Success! Success!" Xu Chen laughed out loud at this moment, like a child.

……

"Boss, I haven't counted the cargo capacity yet! I don't believe that this ship can still have this speed when it is full, and the ship must be empty!"

Jiang Liu was speechless, his face was full of earth, but a boatman behind him stood up and questioned.
