"Ah, look, the ship, the ship, the ship is..." A sharp-eyed sailor on the ferry suddenly pointed at the transport ship and shouted
"Look, the ship is moving!" After the man shouted, more and more people noticed that the ship was really moving again, and the speed also slowly increased.
"Haha, we succeeded. We succeeded, patriarch. You really know everything and are omnipotent!" Everyone gathered around the patriarch Hua Xi and shouted excitedly.
"Haha, okay, now how about you go sailing with me and test the speed of the new ship?" Hua Xi said with a smile, her mood was also surging, and she couldn't calm down for a long time!
"Follow the clan leader to the death! The clan leader, inherits the martial virtues and benefits the common people; the Chinese clan, for thousands of years, will dominate the world!" All the sailors shouted in unison (the latter sentence was added by me as a joke). Because of the reason in the bay,
It is a natural and excellent harbor with good wind shelter, so the sea breeze in the bay is very weak. The effect of the sails has not been reflected for a while, and the speed of the boat is still maintained at a turtle speed. Even the rafts that go out to fish are faster than the boat.
Several times faster
Amid everyone's slightly skeptical, but mostly eager gazes and expectations, the transport ship finally left the harbor after a cup of tea. At this important moment when the new ship left the port and tested the new bamboo sail, naturally
Indispensable, there are groups of rafts and warships following the new ship. Primitive means of transportation on the sea, large and small, are crowded around the new ship. Countless pairs of eyes are eagerly watching the bamboo rafts hanging high on the ship's masts, and always paying attention to the wind direction.
and changes in wind strength
As soon as the new ship came out of the bay, its speed immediately changed a lot. God also took advantage of this happy moment, and the wind direction suddenly changed, turning to the west wind and a little southerly. Although the wind was not very strong, the impact was still strong.
The steady wind on the bamboo sails has made the relatively large new ship a little faster than the flexible warship. As the new ship sailed farther and farther from the shore, the wind became stronger and stronger. Finally, the new ship sailed farther and farther from the shore, and the wind became stronger and stronger.
The ship used the power of the wind to leave the warship powered by oars far behind.
"Wow, clan leader, the boat is really fast!" Shuitong stood on the side of the boat, holding on to the side of the boat and said excitedly.
"Yeah, I never thought that we could use wind to make such a heavy ship sail so fast!" Mulu, the main shipbuilder, and several shipwrights also said in unison.
"Haha, now I want to teach you how to control the sail and make the sail and rudder cooperate with each other!" Hua Xi laughed.
Hearing that there was something new to learn, the sailors cheered up and stared at Hua Xi's every move without saying a word. The reaction of the shipwrights was also the same, because the shipwrights needed to know more about shipbuilding methods and experience.
, you must know how to operate a ship. Otherwise, how can you come up with practical improvements without practicing?
Hua Xi first took out a thin animal skin and placed it in the air. Under the constantly blowing sea breeze, the animal skin was fluttering. It was obvious that the southwest wind was blowing now.
"Can you tell what kind of wind is blowing from this animal skin?" Hua Xi shouted
"Southwest wind!" Sailors who have sailed many times can naturally tell the direction of the wind from the sway of the animal skin at a glance.
"Okay, now our ship is sailing southwest and I want to turn south now. How can we keep the ship's speed at the maximum?" Hua Xi asked everyone.
"Just turn the rudder!" Most people said in unison, because this is a common sense issue, and any sailor who has sailed knows this.
"Yes, but in this case, the ship will still sail a little westward instead of heading south!" Hua Xi said with a smile.
"Patriarch, do you need to move the bamboo sail? Change the angle between the surface of the bamboo sail and the wind direction?" Suddenly, a strange voice came out among the crowd's response.
Hua Xi was shocked. How could the clansmen think of this? Hua Xi quickly looked around and found that it was Shuitong.
"That's right, Shuitong, how did you come up with it?" Hua Xi asked strangely, with a look of admiration in his eyes.
"Haha, clan leader, isn't this all what you taught me?" Shuitong shook his head slightly in embarrassment and replied with a smile.
"Did I teach you?" Hua Xi asked in surprise.
"Yes, Patriarch, have you forgotten that there is a subject called physics in Zhonghua College? It talks about wind force and angles!" Shuitong said in surprise.
"Ah, yes! I almost forgot that you are a missionary and you can learn these things from the priest!" Hua Xi suddenly realized.
Amidst Hua Xi's admiration, the sailors looked at Shuitong with envy. Being able to study with the priest is the greatest honor second only to studying with the clan leader! Fortunately, the clan leader is different from the leaders of other tribes.
This is too high and mighty, everything is so amiable, and imparting all knowledge to the tribesmen. Perhaps this is the essential difference between the leaders of gods and mortals.
"Yes, as long as we twist the bamboo sail slightly and change the angle between the bamboo sail and the wind, the speed and direction of the ship will naturally change!" Hua Xi said while twisting the wooden piece connecting the top of the T-shaped mast.
Liang's five or six reins were pulled hard to the right for a while, and then tied to the side of the ship.
At the same time, Hua Xi shouted to the sailor at the stern who was controlling the rudder: "The ship is heading due south, turn the rudder!"
The sailor who controlled the rudder had already figured out the current and wind direction. When Hua Xi gave the order, the sailor made a slight change to the rudder based on past experience. Just such a change. The rudder cooperated with the bamboo sail to move the ship.
The sailing direction slowly changed with the changing direction of the bamboo sail. The speed of the ship seemed to be slowed down a lot. The people standing on the deck seemed to feel that the center of the earth had changed. Their bodies tilted to the right, and the course was changing.
change
In just one cup of tea, the transport ship was sailing quickly towards the due south pointed by the compass. Then, Hua Xi asked the sailors to drive the ship in person, manipulating the bamboo sails and rudders, and cooperating with each other to operate the transport ship in different directions.
While sailing in the same direction, Hua Xi was constantly guiding the sailors on what to pay attention to. Soon, most of the sailors were able to control the bamboo sails more skillfully, and cooperated with the rudder to allow the ship to sail in different wind directions, so as to achieve a comparison as much as possible.
high speed
During this trial voyage, not only did the sailors get training and learn about sails, but Hua Xi also personally manipulated the sails and taught the sailors, and finally knew what the jib, the quadrilateral, and the sails on the bow and stern of the ship were for.
During the age of human navigation from the 15th to the 17th century, the jib and quadrilateral sails created were indeed very important. As the main power sail, the large area of the quadrilateral sail can provide sufficient power for sea-going ships. The bow and stern mounts
The jib can provide more sufficient power for the ship to change direction, so that when the ship is turning, the jib can make the ship more flexible and faster. In a sense, the jib is the directional sail of the ship.
, and the power quadrilateral sail, which can also provide additional assistance to the sailing ship, is the power sail of the sea ship!
After the sky got dark, the ship, under the control of everyone, slowly sailed to the vicinity of the bay. Because the wind force had weakened significantly, the speed of the ship had also been greatly weakened.
"Okay, let's furl the sails! The inertia of the current seagoing ship is enough to allow the ship to return to the ferry." Hua Xi looked at the slightly bulging bamboo sails and the retreating water, and shouted loudly
"Yes!" the sailors responded in unison.
Soon, the bamboo sail was lowered, and the ship's speed also slowed down the moment the bamboo sail came down. Unfortunately, there is always a gap between the budget and the reality. The inertia of the sea ship is indeed enough for the ship to return to the ferry, but the inertia is very sufficient.
In Hua Xi and others' exclamations, the ship inevitably hit the ferry.
"Hurry up!" The tribesmen on the ferry saw the ship, which was several meters high, approaching like a mountain. Although the speed was not high, the pressure made them feel a hint of danger, and they all shouted and ran away from the ferry.
"Boom -" Although the impact was not very violent, it still smashed the fragile ferry to pieces, and the people on the ship were also shaken to the ground by the shock of the impact.
"Hurry, go and see if the transport ship is damaged, hurry!" Hua Xi, who was anxious about the ship, lay on the deck and shouted loudly at the person with his identity.
After a while, several sailors came back and shouted: "Chief, there is no damage. The parts of the hull that hit the ferry are still the same as before!"
"Huh..." After confirming that the hull was in good condition, Hua Xi relaxed his heart in his throat and exhaled a long breath.
"Patriarch, don't worry, the wood used to build the ship is all pear wood and lychee wood, which is very strong! The ferry is just ordinary wood, and it has been soaked in sea water for so long. The bottom has already rotted! How can it withstand the new
The ship collided like this!" Mulu, who had calmed down from panic, stood up with Hua Xi's support and said.
"Well, I just attach too much importance to this new ship!" Hua Xi nodded, and then stepped off the new ship.
After such a collision, Hua Xi woke up, and there was still one thing missing from this ship - "Ying!"
The anchorage is the earliest mooring tool for ships, and it is also the originator of anchors!
A stone anchor from the late Neolithic Age was unearthed at the Hemudu site in Yuyao, Zhejiang. It can be said to be the earliest anchor. The early anchor was made of stones tied with ropes. When the ship was anchored in the water, the stones were placed on the bottom of the water to use the strength of the stones.
If you want to sail a weight-fixed ship, you only need to pull up the rope and the stone, which is very convenient. However, these primitive anchors have a drawback, that is, they can only be used on rafts and small boats, and are not suitable for large ships.
Although the new ships being built now are small ships in the history of mankind, they are still sea ships that can carry thirty people. The weight of the hull itself is no longer enough to be anchored by just a few stones. It is necessary to berth such ships that go out to sea.
, must change the shape, rather than blindly increase the weight of the stone
The original four-claw anchor in ancient my country still plays an important role in the world today. Simple and easy to make, and its strong grip are the main reasons for the enduring popularity of the four-claw anchor. In addition to the four-claw anchor, there are many triangular or and The anchor is like a plow, but Hua Xi still loves the four-claw anchor.
Hua Xi’s classmates from his hometown use four-claw anchors for their seagoing ships. With just four claws, they can anchor a fishing boat. This shows the advantages of four-claw anchors.
To make a four-claw anchor, you can use wood, stone, or bronze to make it. Hua Xi naturally chose bronze to make the four-claw anchor. The four-claw anchor is very simple to make. It is to weld four large hooks to a main handle.
Just weld them together at 90 degrees. After Hua Xi explained and drew an original drawing on the paper, the craftsmen quickly built a four-claw anchor weighing over a hundred kilograms.
A few days later, the four-claw anchor was transported back from the iron wall and sent to the newly built dock.
"Come on, lift this four-claw anchor to the ship. Let's go to sea and see if we can stop the ship!" Hua Xi greeted the sailors and lifted the four-claw anchor to the ship.
While the ship was sailing, Hua Xi tied the long rein tightly to the loop specially made by the four-claw anchor. Not long after, the ship sailed out of the bay and came to the shallow sea.
"Lower the sails! Drop the anchor!" Hua Xi gave the order to drop the anchor to see if the ship could really be anchored.
"Yes!" In the response of the sailors, the anchor weighing hundreds of pounds was thrown into the water from the stern of the ship by three sailors, and the bamboo sail was quickly lowered.
With a "bang" sound, the anchor quickly disappeared on the water and sank into the water. The reins tied to the anchor also quickly submerged into the sea water under the action of the pulling force. The reins tied to a newly designed steering handle quickly
The ground started to turn in circles, and the hand uncle made a whirring sound.
After about tens of seconds, the handle suddenly stopped rotating rapidly and slowed down greatly. It was obvious that the anchor had fallen to the bottom of the sea. Hua Xi quickly grabbed the handle, then stuck a large wooden stick on the handle, and pulled the handle away.
The rudder is fixed
Boom————The sea-going ship suddenly experienced some obvious lag, and the hull experienced violent vibrations and swaying. The originally loose reins also tightened instantly. It was obvious that the four-claw anchor that had fallen to the seabed was using the sea-going ship to sail.
Pulling force, constantly grabbing the ground and rocks on the seabed
Not long after, the ship finally stopped sailing forward and drifted back and forth within a range of about tens of meters.
"Chief, the ship has anchored, it has anchored!" Every success surprised these sailors, and their excitement was palpable.
"Well, now pull up the anchor," Hua Xi nodded.
"yes!"
After a long time, the anchor was put away. Although the anchor was put away
