Daming Town Haiwang

Chapter 162, stargazing

In the Bohai Sea, the five blessing boats are separated by hundreds of meters from each other, looking out to each other, sailing quietly in the turbulent waves.

On the 'Taishan', Tian Erniu was basically free from seasickness, because he found a way to divert his attention, that is to get busy.

Walking around on the ship, constantly inspecting every situation, putting all my attention on the work on the ship, I quickly got used to it.

"Uh~"

The situation of Sha Xiong is still not very optimistic, and even looks a bit serious, but Sha Xiong seems to be stimulated by Tian Erniu's words. While seasick and vomiting, he keeps carrying heavy objects and diverting his attention. Ginger slices, rely on the pungentness of ginger to stimulate your brain nerves and relieve the symptoms of seasickness.

There are people on the boat and other people are in the same situation. Some people quickly adapt to the bumps on the boat, some people are not born with seasickness, and some people are like the silly bear. The situation is a little serious, but they are still persisting. .

The sun gradually set in the west, and the afterglow of the setting sun turned the place between the sea and the sky into a fiery red world, which was so beautiful and spectacular that Tian Erniu was stunned.

"It's so beautiful!"

Tian Erniu couldn't help sighing softly.

Soon, night fell, and the silver moon hung high in the sky, casting a trace of cold moonlight. Under the moonlight, everything became darker and hazy. Only the lights from other adjacent ships could make the You feel a sense of security.

Otherwise, in such an environment, people will feel lonely and feel as if they have been abandoned by the world.

Tian Erniu took out a pen, paper, compass, and sextant. The pen is a black charcoal pen specially made by Liu Jin, not an ink pen. Naturally, it is impossible to use an ink pen when the boat is bumping all the time. It is more convenient to make something like a pencil to write.

Needless to say about the compass, the compass has always been used to look at Feng Shui. It is not difficult to make a qualified compass without any technical content.

The true nautical magic is the sextant, which was first invented by Europeans in the 18th century. It is an optical instrument that can measure the angle between two distant targets-the most commonly used is The latitude of the observer can be determined by measuring the angle between the celestial body and the sea (horizon) or between the celestial body and the celestial body, measuring the angle, and then checking the latitude of the direct sun point on the day according to the calendar.

The sextant is considered to be the most important positioning and navigation instrument in the nautical age, and it was not really invented by Europeans until the 18th century.

Of course, its principle is not complicated, it is very simple. What is really difficult is to make the colorless glass of the sextant and the telescope. The colorless glass was not made by Europeans until the [-]th century, and the telescope was not made until the [-]th century. was invented.

Now that Liu Jin has made colorless glass and understands the principles and methods of making telescopes, there is no problem in making a sextant.

Tian Erniu skillfully placed the sextant on the horizontal position, pressed the clip, released the reading ruler, adjusted the Polaris to the sea level in the field of vision through the telescope above the sextant, and then began to constantly adjust the reading ruler below position, so that the position of Polaris is in the middle of the field of view of the telescope.

Then swing it repeatedly to make sure that Polaris is indeed in the middle of the field of vision, and then write down the degree, then turn to the comparison table designed by Liu Jin, and start to keep counting on paper with a pen.

"39 degrees 12 minutes north latitude~"

Soon, Tian Erniu calculated a result, and then carefully recalculated several times, the difference between the obtained data was very small, and he could basically determine his position.

He took out a simple globe, found the location of Bohai Sea on the globe, opened the map, and recorded today's location in his nautical diary.

"It's Er Niu, you are amazing, you can understand such complicated things."

Zhao Houzi has been following Tian Erniu's side, seeing Tian Erniu's busy appearance, he is very envious.

If a student of the Maritime Academy wants to be a captain, the first thing to do is to learn to use a sextant. Calculate dimensions according to the Polaris, which requires a good brain and good mathematical knowledge.

Although Zhao Houzi is known as a monkey, he has always been unable to learn it. Tian Erniu is willing to learn it with his heart. After learning this thing, coupled with his performance in other aspects, he became the captain of the Taishan.

"This thing is actually very simple. As long as you learn it with your heart, you will learn it soon. Come on, let me teach you. You have already learned the use of the sextant. Now the most important thing is mathematical calculation. This There are formulas in it, and we can calculate the dimensions of the ship based on the measured angles.”

Tian Erniu smiled, and then began to teach Zhao Houzi hand in hand.

Life on board is actually very boring, because the ship is so big, all the space is fully arranged, and sleeping is also a very painful and difficult thing for the crew.

The sound of sea water on the sea has been ringing non-stop. From time to time, some people are seasick and vomit. In addition, the ship is constantly heaving and drifting with the waves. Most of the more than [-] people on the Taishan have difficulty falling asleep and can only lie on the bed. I kept tossing and turning, and sometimes I really couldn't sleep, so I hurried to the deck to enjoy the cool night.

The next day, Tian Erniu was woken up by the screams of seagulls, put on his clothes and went outside, and found groups of seagulls around the boat.

These seagulls fly in the sea, and they also need a place to rest. Ships sailing in the sea knock on the mast that can provide them with a rest, so the presence of seagulls is always indispensable around the ship.

"The Bohai Sea is an inland sea. It's very close to the coast. It's normal to have seagulls."

Tian Erniu remembered what Liu Jin said in class, the seagull cannot be too far away from the land, so if there is a seagull, it means that there must be land around, and this is also the reason for looking for land One method, Tian Erniu firmly remembered this point.

"creak~kick~"

Just as Tian Erniu was watching the seagulls thinking, the beams and wooden frames supporting the trawl net made an unpleasant sound, which immediately gave people goosebumps and a toothache feeling.

"Monkey, ring the bell immediately. It's time for our trawl net to be collected. It seems that the income should be quite a lot, otherwise we wouldn't make such a sound."

When Tian Erniu heard it, and then looked at the supporting beams showing a slight arc, he immediately said to Zhao Houzi.
