I have a sea in ancient times

Chapter 331 Compass and Sextant
Ever since he saw the number of fish schools in the warm current zone of Aomori County in the Neon Country, Lu Hai has always wanted to do something after returning to his country.

Always fished in coastal areas.

Waiting for the fish to come by itself is really not an option.

Coupled with the fact that he has 100 million acres of exploration space on hand, which has not yet been allocated, Lu Hai always feels that he can do something.

Like going on a voyage or something.

During this period of time, he has been studying nautical charts and learning some traditional fishing boat driving knowledge, such as how fishing boats go to sea in the era without GPS.

There is also some learning about sudden sea conditions, such as how to deal with big waves and strong winds, etc.

For land and sea, a large number of radio signal buoys was ordered from a buoy factory.

This buoy is placed in the sea.

Even if there is no GPS, you can also point out the direction to the fishing boat, as long as you set a simple data, you can also know where the fishing boat is.

The premise is: the world of exploring space is consistent with the real world.

And Lu Hai, who has been observing for so long.

Not just from Xiaqi Island.

It is still the waters around Aomori Prefecture, the overall similarity reached 99%, but some coral reefs are quite different.

There are no coral reefs around Xiaqi Island for a long time, but in the exploration space, there are still a large number of coral reefs, and there are even guano islands.

Explore the space.

The transport ship was carrying a large number of signal buoys on the sea. Lu Hai planned to go to the easternmost part of Wanwan Province, a hundred kilometers away, and drop the radio buoys along the way.

Transport ships are slow.

Only about ten verses like this.

In conversion, it is about 18.52 km/h.

at this rate.

It will take at least ten hours to drive to reach the destination that Lu Hai wants to go to.

Since there is no GPS.

Land and sea had to use a compass for orientation and then a sextant for orientation.

The use of these two things was taught by his grandfather. At the beginning, due to backward technology, domestic fishing boats could only navigate in this way when they went to the open sea.

If the world of space exploration is still the original earth, then there is no GPS.

Through the sextant, observe the height difference between the sun, the moon and the sea level at a specific time, and read the included angle on the sextant.

Then, by comparing with a special table, you can know the latitude and longitude where you are, and you can roughly determine your location through the latitude and longitude.

Using these two ancient technologies, Luhai's fishing boats are driving on the sea surface. In order to facilitate the fishing boats, Luhai has determined the exact position.

Directly in the exploration space, a 200-meter-wide and 15-kilometer-long navigation channel was purchased, consuming a total of [-] mu of exploration space.

Every 10 nautical miles between land and sea.

Just throw a radio signal buoy for positioning, and the receiver on the fishing boat can clearly know the position of the radio buoy.

After having this stuff.

Even if Lu Hai is not around.

With these wireless buoys, Xiaobai will not get lost at sea. At the same time, Lu Hai taught her how to use the compass and sextant.

It is unrealistic to buy the entire ocean area of ​​the earth, but Xiaobai, as a native of space exploration, is not limited by space.

Feel free to go anywhere.

For example, if you master it well in the future, you can completely drive the fishing boat to the exploration space in Aomori County. Lu Hai only needs to fly there, and enter Aomori County from the landing point to meet Xiaobai and the others.

At that time, after fishing, Xiaobai will sail the boat to transport the things back, and he does not need to go back with the boat. With this method, he can even go to Australia to catch lobsters, king crabs, etc.

The products sold in the future will not be so monotonous. They will always be these things, these things caught in the open sea, and they need to be declared. Uncle Zhao emphasized this point.

If there is a declaration, it is not called smuggling. If there is no declaration, all the products sold in the market will be dealt with as smuggling.

As for what Lu Hai caught.

According to Uncle Zhao's words: In theory, even if you catch a whole boat of bluefin tuna, as long as the other party doesn't catch it on the spot, you can fish in other people's territorial waters.

Then
The fish is still yours, unless the other side can provide real evidence, otherwise you can say that it was caught on the high seas.

After all, the migration of marine life is not so stable. There will always be a few horses, which may lead the way astray and take the group to other places.

In the same way, other seafood is the same, that is, some endangered marine life, try not to touch it, because it will cause a lot of trouble.

After Lu Hai avoided the risk through the official explanation.

Probably know a truth.

Work hard to pay taxes, as long as you don't smuggle. To put it bluntly, even if it is another world's resources, as long as you pay taxes and pass the safety inspection.

Then it's legal.

The transport ship sailed on the sea for about 10 hours, and set off at dawn. The sun is now slanting westward, and a lot of fish were found along the way.

Lu Hai passed the sextant and tested it.

latitude 25°.30 north,

121°.53 E,

Lu Hai didn't check the chart, picked up his phone directly, opened an app, entered specific information, and found that he had already reached the easternmost part of Wanwan Province.

Land and sea slowed down the transport ships.

(Funny, already slow.)
Using a DJI drone, I flew to a high altitude to investigate the situation in the nearby sea area. As a result, when I rose to an altitude of 1000 meters, I passed the transmitted image.

It can be found that there are several small islands directly in front of the bow, and a vast land to the west.

If it is correct, the protruding land in the west should be the northernmost Fuguijiao Lighthouse in Wanwan Province.

Lu Hai stopped the transport ship.

I don't know where I got a red flag, put down a spare speedboat on board, and set off towards the protruding land.

After login.

The national flag of the motherland was directly inserted on it. In reality, there is no way to insert it. In this exploration space, insert it first. Although it is useless, it is cool!
After returning to the transport ship, Lu Hai did not stay, but chose to continue, this time the destination was the Yaeyama Islands, which is difficult to face in Wanwan Province.

Although this island is very close to the Wanwan Province of the motherland, it belongs to the Neon Country and belongs to Okinawa County. It is about 400 kilometers from the Fuki Cape Lighthouse to the Yaeyama Islands.

Luhai spent another 30 mu of exploration space, extending the scope of exploration to the Yaeyama Islands.

As for why Lu Hai wants to go to that place, the reason is relatively simple. It is where the Kuroshio Current passes. Relatively speaking, the fishery resources are relatively rich.

At the same time, there are also a variety of large fish, such as swordfish, bluefin tuna, yellowfin tuna, etc., and even eel fry rely on this Kuroshio warm current to go to the coast.

According to the speed of the transport ship, it will take about 20 hours to reach the destination.

After the sky darkened.

It didn't take long for the land and sea to darken, and the night darkened. The fishing boat was driving slowly on the dark sea. In the moonless sea, the night was really quite scary.

It was pitch black all around.

Fortunately, Lu Hai has already determined the direction to go, and because of the exploration of space, the fishing boat seems to be driving on a big river, and there is no need to worry about drifting, just go forward boldly.
