Xu Yuanzuo was no stranger to Ming Dynasty ships – just when they were in books. When he got to the ship in person, it took two days to find out that it was a lucky boat, not a preconceived sand boat.

Indeed, although the Shen family is famous for the Sand Boat Gang, they can't prohibit people from using the lucky boat. They can even buy a Tessie boat, but they just don't want to.

"It's not bad to ship Tessie, it's just not good for sailing offshore. They use soft sails and high masts, although the wind surface is large, but it is easy to twist and turn and lose the wind, which is not as good as our hard sails. Shen Yujun is very familiar with this: "And the hard sail is also easy to operate, and no one needs to climb onto the mast." Many of them fall from the mast and die every year. ”

Xu Yuanzuo didn't know much about this, and with his shallow knowledge of physics, he could barely make up a few figures in his mind. He added, "Then according to you, what kind of ship is good when it comes to the ocean?" ”

Shen Yujun thought for a while and said, "If you go to the ocean, maybe the Taixi ship is better." She added: "In the end, people can sail thousands of miles to our doorstep, but it is a little difficult for us to drive so far." ”

"How do I think I can drive far, the key lies in the port supply along the way......" Xu Yuanzuo said weakly.

Shen Yujun thought about it again: "Their ship is indeed faster than ours. In terms of commerce and trade, one day later than others, the price of goods is afraid that it will be suppressed. But now that the Fur Men of Oyster Realm have loaded our hard sails on their ships, they also think that it is better to still be our hard sails near the sea. ”

"I see." Xu Yuanzuo has won popular science, and his confidence in maritime trade is even stronger.

Shen Yujun said that he was addicted, and then popularized the truth that the flat-bottomed sand boat took the northern route, and the sharp-bottomed Fu boat took the southern route. Because there are many dark sands in the northern coastal waters, it is not easy for flat-bottomed boats to run aground. The south is deep and less sandy. With multiple islands and reefs, the culet boat is more agile and faster.

Xu Yuanzuo listened to it with relish, but he couldn't accept that Ming Ren gave a name to every kind of ship. Just listening to the sea eagle ship and the egg boat, God knows what type of ship it is and how much it is loaded. If you can use the No. 1 Fu boat, the No. 2 sand boat, 、......、 the No. 9 sentry ship...... From big to small. Wouldn't it be clear and clear to classify and name ships like this?

Shen Yujun listened to Xu Yuanzuo's idea and scoffed: "What you want is that you landlubbers can't understand!" ”

- Otherwise, how would you make money from landlubbers?

Xu Yuanzuo secretly added a sentence to Shen Yujun, and led the topic to the "needle road".

The needle road originated in the Song Dynasty, because the most important thing in the navigation identification route is the needle - the compass, so the name is actually the route.

Under the guidance of the compass, there are directions of navigation from a certain point to a certain place on a certain route from A to B, and these courses are connected into a line. And painted on paper, that is, the needle warp, the needle book. From A to B, the needle path on different routes is different; Going back and forth on the same route, the needle path is not the same.

When the ship sails at night, it is necessary to write the record of the star in the needle path. During the voyage, the depth of the water must be constantly measured, and the needle path must also be written.

If you leave the needle, you will have no eyes. Once the course is deviated, it encounters undercurrents and reefs. All of them may cause the tragedy of ship destruction and death.

The navigator who masters the needle path has a very high status on the ship, if not the captain. It's the fire chief.

The Shen family also has a few needle scriptures, which are handed over to the nephews of the clan to use when Shen Benjing is not out of the sea. Even so, it is necessary to disassemble the needle warp, and one person can only master one trip. Although Shen Yujun goes to sea all the year round, it is because it is his daughter's family. I also don't know much about the needle scriptures.

As for those hired fire chiefs, they are extremely well paid, with bonuses and shares, and they each hold an ancestral needle scripture. Never show it easily. Even an owner like Shen Yujun can't peep.

Xu Yuanzuo was puzzled after hearing this, and said: "Since he follows the needle road, then the route should be the same every time." ”

"Of course." Shen Yujun couldn't understand why Xu Yuanzuo asked such an obvious question.

Xu Yuanzuo said again: "Isn't it possible to trace the needle path after walking so many times?" ”

Shen Yujun almost laughed: "The wind direction and wind speed are not the same, how do you describe it?" ”

"The speed and direction are recorded at all times, and the voyage is calculated according to the sailing time. When I reach a certain point and turn to the course I have traveled, why should I care about the direction of the wind and the speed of the wind? Xu Yuanzuo looked puzzled: "And often measure the water depth and mark the islands and reefs, maybe you can improve the needle path." In the end, the French way of shipbuilding has been changing. ”

Shen Yujun was stunned: It seems very simple to tell him!

――It's easy! If the speed is fast, then what is recorded is the broken line, and there is danger. Nowadays, this maximum speed is only seven or eight knots, and it is accurate enough to remember it once in five minutes.

Xu Yuanzuo said: "Send another shrewd person to the side of the fire chief, and record every order he makes, so how can you not trace the needle spectrum after five or seven times like this?" If you want to be a little more cautious, you can also send an empty boat to explore the way before the official voyage to make sure that it happens. Isn't it better than being held in the hands all the time? ”

Shen Yujun did not doubt that Xu Yuanzuo was reasonable, but he refused to bow his head and soften: "This is a rule since ancient times, and if the rules are broken, I am afraid it will not be beautiful." ”

――It's a little unkind to learn other people's crafts and kick them aside!

Shen Yujun was secretly entangled in his heart.

"You have your own needle path, you can expand the fleet, and it doesn't prevent you from treating the old man well." Xu Yuanzuo said: "And the more money your family earns, the better the benefits for your employees, the more willing they are to work for your family." What's not beautiful about that? ”

"Hmm...... Let's see. Shen Yujun suddenly felt that his realm was slightly lower, and he actually started the idea of crossing the river and demolishing the bridge to unload the mill and kill the donkey, he was not as good as a bear child, he was really ashamed.

Xu Yuanzuo continued to pay attention to the ship, asking some familiar but never-before-seen proper nouns, which greatly improved his knowledge system.

The boat traveled for a day and a night, and finally saw the land before noon the next day, and after another section, the color of the water body was obviously differentiated, and it was to the mouth of the Cao'e River.

You have to change to river boats to get in, and the larger ships will run aground because of the lack of draft.

Shen Yujun sent someone to put down the firewood boat, and in a short time, the boat brought a river boat with a different style from Sha and Fu.

"This is Zhejiang's bird boat." Shen Yujun knew that Xu Yuanzuo was interested in the boat, and he was happy to say more.

Xu Yuanzuo looked at it and asked, "Where is the bird?" ”

Shen Yujun glared at Xu Yuanzuo: "Can't you see that the bow of the ship looks like a bird's beak?" ”

Xu Yuanzuo listened to Shen Yujun's answer, and then looked closely, it really looked like a bird, it was really three parts image and seven points imagination.

"Zhejiang, especially here, has a lot of beaches in the north and reefs in the south, so this type of ship is quite enjoyable." Shen Yujun said again: "I'll wait for you here." ”

After saying this, I felt that it was a little misleading, and I couldn't help but jump in my heart, and my face was slightly red. (To be continued......)
