Jack shrugged his shoulders and said, "Who made me the deputy boatswain?" You know, it's not a popular position on the ship. But the good thing is that everyone is in awe of this position. And they couldn't beat me in a fight, not to mention that I had been on the ship longer than all of them. So naturally they will listen to me. ”

Jack bowed and said, "As you wish." ”

At this time, Liu Pei suddenly roared: "Now the south wind is blowing!" The wind is very strong, force seven. ”

The calculations followed the rapid movement of the command, and in a matter of moments, all the mainsails were lowered by one notch. The spinnaker was also pulled up quickly. Liu Pei's movements were in place, and he nodded dissatisfied. Even Jack made a smug face at Liu Pei.

Jack, who had been prepared, immediately commanded loudly: "Put away the spinnaker!" All mainsails are lowered one more block. Attention helmsman, zigzag sailing. Sailors who keep timekeepers pay attention to timing. ”

The sailors cheered quickly after listening to Liu Dahai's translation. Liu Pei continued: "Because of your outstanding efforts, your salary will increase by 20% every month! At the same time, I appointed Jack Jack as the chief instructor of the instructor corps. His salary will go up by 50%! ”

Liu Pei said: "So do you still have any problems to solve in your life here? ”

Liu Pei said

Jack said unhappily, "Okay, boss, we can accept this." But there is a more serious problem. That's that there are no women here, it's all men, and it's terrible! And we went to the hospital, but the hospital refused to receive us! And say that we are barbarians! I don't know what barbarian means, but I guess it's certainly not a good name! ”

So Liu Pei thought for a while and said, "Okay, I'll help you solve this problem." How about finding a wife for each of you? ”

After they finished asking questions, Liu Pei said, "Then do you think there are any other things to pay attention to in training?" ”

Liu Pei was also very proud and said, "Then implement it as soon as possible, understand?" Do you have any other questions? ”

Liu Pei said solemnly: "Jack, don't even think about this!" These secrets must be kept in our fleet. Don't forget that you're getting my salary. Also, Jack, if you can keep these secrets from the rest of the world, I can give you an additional silver bounty, 100 taels each! What do you think? ”

Of course, Liu Pei is not worried about them leaking out. Because Jack, these people at the hands of the sailors, are all

At that time, it was easy to determine the latitude when it was at sea, and it was possible to determine it by the height of the North Star or by using the height of the sun in the sky. However, it is much more difficult to determine longitude, and the longitude can only be estimated by measuring speed and other auxiliary methods. More often than not, the captain relied on experience to deal with the ship, and there were often shipwrecks caused by miscalculation of the position of the ship.

In 1714, Parliament passed the "Longitude Act", declaring in the form of law that the longitude measurement at sea can control the error within 1 degree and reward 10,000 pounds; If the error is less than 2/3 degree, the reward is £15,000, and if the error is less than half degree, the reward is £20,000.

That's when a carpenter's son, John Harrison, appeared. Harrison was born into a family of carpenters in Yorkshire, England, and although he learned his father's skilled carpentry, he did not follow his father's business and moved to mechanical watches.

As for the latitude and longitude, Liu Pei proudly named his pier 0 degree longitude! Anyway, in his opinion, the reason why everyone adopted the longitude and latitude standards formulated by the United Kingdom was simply because Britain was strong enough at that time. When he becomes strong in the future, maybe the whole world will act according to Liu Pei's standards. Anyway, Liu Pei had already started training sailors among those orphans. They used Liu Pei's standard latitude and longitude. As for marine clocks, is it hard to buy a watch in modern times?
