Daming: The system rejected my request for salted fish

In fact, Wei Wu did not drive the yacht at a very high speed.

After all, this trip to the sea was not for fun, but to prevent the Japanese pirates from leaving, so he would not go too far away from the seaport.

As before, the ship will probably only stop in the sea area about ten to twenty kilometers offshore to facilitate radar scanning.

After all, although the radar on the yacht has a detection range of 25 nautical miles, due to various factors, the actual range may only be 10 nautical miles.

After coming out of the seaport, Wei Wu sailed for about three hours and dropped anchor eighteen kilometers offshore.

As soon as the ship stopped, he turned on the ship's navigation radar to scan the surrounding waters.

Today is a sunny day, and the performance of the radar is close to the theoretical value, directly covering the surrounding twenty nautical miles.

In an instant, more than a dozen ships around the yacht appeared on the radar.

Seeing the small dots displayed on the screen, Zhang Hai was completely confused and had no idea what they were.

After hesitating for a long time, he finally couldn't help but ask.

"Master, what is that thing that keeps spinning around, and those little flashing dots? Why are you staring at it?"

Wei Wu felt a little bored sitting in front of the radar, and then he saw Zhang Hai's eyes full of curiosity.

Wei Wu thought for a while and decided to explain to Zhang Hai the function of radar and its operating principle.

Later, in Wei Wu's description, Zhang Hai's expression quickly changed from initial confusion to shock.

"Young Master, are you saying that electromagnetic wave thing can detect a distance of nearly a hundred miles in an instant?"

One nautical mile is equal to 1.85 kilometers, and 25 nautical miles is equivalent to 46 kilometers, which is almost the same as miles.

So what Zhang Hai said about the radar detection range being nearly 100 miles was not wrong, but his reaction was still a bit too exaggerated.

Wei Wu didn't know how to respond, but at this time, Zhang Hai continued to point at the radar screen and said:

"And those tiny flashing dots on this thing are the ships it detected dozens of miles away? This is too, too, too..."

Seeing that Zhang Hai couldn't say anything for a long time, Wei Wu simply interrupted him.

"Too much, too much! The Institute of Science and Technology can already produce electricity, you know that, why is there such a big reaction?"

"Electromagnetic waves are just another form of electrical energy. How are you going to hang out with me in the future if you're making such a fuss?"

After saying a few unpleasant words to Zhang Hai, Wei Wu turned his attention to the radar screen to check the ships scanned by the radar.

Most of these ships were sailing along the coastline, and a small number of ships remained where they were.

There was only one boat behind the yacht, sailing towards the deep sea, but the boat stopped not long after.

Wei Wu originally planned to ride a motorboat to investigate, but he immediately gave up the idea after seeing this situation.

The reason is very simple. If it was a Japanese pirate ship, it would not stop but continue to move towards the deep sea.

Since the boat has stopped, it is likely that the fishermen are fishing near that sea area.

The fact was just as Wei Wu guessed, the ship stayed in the same place for about an hour.

It was not until the sky darkened and the sun was about to set that it started moving again, heading towards the coastline.

During this process, Wei Wu stared at the radar screen while explaining to Zhang Hai so that he could get started quickly.

Fortunately, it was not difficult to understand the data displayed on the radar, and with Wei Wu's explanation, Zhang Hai quickly knew what to do.

In the following time, the four girls played mahjong on the second deck, while Wei Wu and Zhang Hai stared at the radar screen.
