After the two wooden boat models were fished up, the old man looked at Fang Zi'an proudly and said, "Fang Gongzi can see that the door is coming?" ”

Fang Zi'an frowned and said, "The two ships are exactly the same, why is there such a big difference in their ability to resist wind and waves?" Is it a problem with the material? ”

"The material is exactly the same, the two wooden boats are made of wood from the same tree, so to speak, they are the same." The old man laughed.

"It must be a structural difference, but I don't see any difference." Fang Zi'an smacked his lips and said.

"Hahaha, Fang Gongzi is really smart, it is indeed a difference in structure that leads to different results. Young Master Fang, please see, what is the difference between the bottom of the two ships? The old man proudly flipped the two models of the boats that had been fished up and put them on the grass.

Fang Zi'an squatted down to take a closer look, and this time he could see the difference at a glance. It turns out that there is a difference between the positions on both sides of the belly of the two ship models. The bottom of one boat is normal, while the other boat has two more side panels on both sides of the belly, like two protruding fins, smoothly distributed from bow to stern, and integrated into the hull. Because of the small size of the model, these two side panels protruded no more than an inch, so Fang Zi'an didn't notice it at all before.

"These two fin-like side plates...... Is that the key point? Fang Zi'an said in surprise.

"Awesome, awesome. Fang Gongzi really impressed the old man and me, and he broke through the trick in one sentence. The word "fin" is used very appropriately. It was only from the fact that the fish did not roll over when swimming and thus understood the wonderful use of the fish's side fins, so he understood that the boat would have the same effect when it was fitted with this kind of side plate. Fang Gongzi saw through it at a glance, it was really admirable. After many comparisons, I found that these two side panels do have a strong effect on preventing the ship from capsizing. That's why I thought of installing this kind of side fin on Childe's ship. That's why I have to discuss this matter with my son. ”

Fang Zi'an smiled: "Since it has such an effect, what is it to spend an extra five hundred taels of silver?" I always think that if I think it is, then I can put it on. ”

Liu Lao hurriedly waved his head and said, "No, no, the old man has to make his words clear, so as not to make the son complain in the future." For one, this side fin has only been tried on small boats, but it has never been installed on a large sea boat. It's one thing to experiment, it's another thing to go to sea and encounter wind and waves. If the effect is not great, and Fang Gongzi's five hundred taels of silver are wasted, then Fang Gongzi will definitely have an opinion on the old man at that time. Second, Fang Gongzi did not look at these two side fin plates as simple, but there were many tricks involved in the installation, and the side fin plates should be deep into the watertight compartment to become a whole, so that it could also strengthen the firmness of the entire ship and the stability it hoped would bring. But what is even more difficult is to be able to move, adjust the angle according to various situations, and maximize stability without affecting the navigation of the ship. Therefore, the construction period that could have been completed in half a month will be extended by at least ten days. The materials of the side fin plates on both sides are also very particular, and they are by no means competent for ordinary ship boards, so they cost as much as five hundred taels of silver. You have to make these things clear to your son, otherwise your son will think that the old man will ask for five hundred taels of silver just to install two side fin plates, which is a black-hearted move. When these things are clearly explained, the old man can feel at ease. ”

Fang Zi'an nodded slowly, Liu Lao is a simple and honest person, he can say these words, it is really honest and has no reservations. Dealing with such a person, Fang Zi's peace of mind is very down-to-earth.

But he also heard it, and the old man meant that his five hundred taels of silver might have been lost

Target. The effectiveness of this side fin has only been tested on models and has never actually been used on a seagoing vessel. In other words, the old boss is actually using his own big ship as an experiment. This made Fang Zi'an hesitate. There were five hundred taels of silver extra for no reason, and the construction period would be delayed by ten days, which would disrupt Fang Zi'an's plan.

Fang Zi'an's original plan was to recruit shipwrights to go to sea as soon as the ship was built, and he did not plan to wait for the winter monsoon. He wanted to take advantage of the time when other ships were waiting for the winter monsoon to go to sea in advance to trade, and make a time difference. In addition, going to sea at this time will not attract the attention of the government, after all, Fang Zi'an did not plan to obtain the government's permission to trade at sea, and at the same time as being extracted by the city shipping company, he had to sell the goods to the city shipping department at a parity price. To put it bluntly, Fang Zi'an planned to use this ship to smuggle trade, beat the time difference, and seek extreme profits. Because he did not have the strength of other shipping companies, he could only go to sea with one ship, and he wanted to grab the maximum profit. This is a very risky thing, and to put it bluntly, it is a one-shot deal. Once successful, the money is full, and the capital is immediately available. But if you fail, you will have no return, and there will be no chance to turn over.

The efficacy of the side fin plates is unknown, and that's fine. However, the delay of ten days had a greater impact on Fang Zi'an's plan. So Fang Zi'an hesitated a little.

"Young Master Fang, the old man knows that this matter is indeed a little embarrassing, and others have rejected me like this before. If you don't agree, the old man won't force it. Don't be embarrassed. Liu Lao looked at Fang Zi'an's face and said with a smile.

Fang Zi'an stood up and said with a smile: "Old boss, you are open and honest with me, and I also have a heart to you." How about we make a deal? ”

The old boss said: "Deal? How is the transaction? ”

Fang Zi'an said: "Since you always think that this side fin plate is very good for the stability of the ship, I will let you go out and let you prove your idea." I give the silver, and the side fin plates can also be installed. However, I have two small requests. ”

Liu turned his head and said, "You say." ”

Fang Zi'an said: "If this side fin plate has no effect, it will be fine, and I will not pursue the wasted silver." But if it really works, from now on, the old boss can only install this kind of side fin for our boat, not for others. Including your apprentices, after learning your method, they can only be used for my ship. This is my first request. I don't know if the old boss can agree. ”

Liu Lao put his head on the spot, and didn't figure out what Fang Zi'an's request was for a long time. He knew that Fang Zi'an was going to use the five hundred taels of silver as a monopoly investment. Once the side fins proved useful for the stability of the boat, Fang Zi'an had to monopolize the technology. Fang Zi'an feels that this kind of technology, which is related to the safety of ships, must be of great value if it is practical. Five hundred taels of silver to buy a monopoly technology, it is definitely a good deal.

Moreover, Fang Zi'an actually knew in his heart that this kind of side fin plate structure should be useful. This is an anti-rollover structure, and Fang Zi'an seems to have seen it there in his memory. So, it's not really a blind gamble. Don't look at the side fin board is only two wooden boards, but the angle length of its installation is actually exquisite. Liu Lao also said that the two side panels can also adjust the angle, which is not something that anyone can imitate. Therefore, monopolizing the whole person of Liu Lao can monopolize this technology.

Old Liu thought for a while, and finally nodded and said in a deep voice: "Young Master Fang, old man, I don't know what your intentions are for doing this

But the only one who is willing to spend money to let the old man confirm this matter is you, Young Master Fang. Well, I promise you. You Fang Gongzi don't nod, old man, I will never pretend this thing for others. Besides, no one wants me to pretend. ”

Fang Zi'an smiled and said, "Okay, the old boss is really human." Then the second condition is that I want to ask the boss to continue to cooperate with me. After this ship is built, I hope that the old boss will continue to repair the ship for me. I'll give the money, you will give the technology and manpower, and let's set up a ship repair yard together. You have such good ship repair skills, we can buy some abandoned ships to repair. or sell or use it to transport things to make money, and there is a considerable income. In this way, the old boss can continue to use your full skills and not be wasted. Second, it is also conducive to the inheritance of skills, so that your apprentices can learn more skills from you, and you can also make money to support your family. What do you think? ”

Liu Lao looked at Fang Zi'an in a daze, and said with a shaky beard for a while: "This ...... Can it be done? ”

Fang Zi'an smiled: "What's not to do?" If you're worried, I'll give you two options, one is to repair the shipyard and you repair the ship for me, and you don't have to worry about the rest. Second, let's operate in partnership, the profit and loss are halved, I will pay the silver, and you will contribute the technology and manpower. The choice is yours. ”

Liu Lao thought for a while and said: "Then I'll choose the first one, the old man, I will work for your son, and the other old men don't understand." ”

Fang Zi'an laughed and said, "Okay, that's done, it's safer to do this." Let's make a decision. ”

Liu Lao turned his head and said: "Don't, I also have a request, the old man can agree to your conditions, but you also have to agree to the request." ”

Fang Zi'an smiled: "But that's it." ”

Liu Lao turned his head and said: "When the ship is repaired in the future, if the old man and I have other ideas about the structure and equipment of the big ship, you have to allow the old man to try it on the ship." Of course, it's all about the stability of the boat's handling and the small idea of driving, and it won't be messed around. ”

Fang Zi said in an an: "Listening to the old leader's tone, do you seem to have many other ideas about ships?" ”

Liu Lao stroked his head and said with a smile: "That's natural, old man, I have been dealing with ships all my life, and I dream of building ships and repairing ships, how can I have no ideas." For example, seeing the eight-sided mast of your ship reminds me of a convenient maneuvering mast sail device that I was thinking about before, and I am thinking about it these days. ”

Fang Zi'an said curiously: "What kind of thing is that?" ”

Liu Lao smiled and said: "It's nothing, it's just that because the mast is raised, it takes manpower to change the sails, and the eight-masted ship like you is more complicated, and it is extremely difficult to control, requiring a lot of manpower and strength." So, what I think of is actually a kind of transmission. To put it simply, it is to integrate the movements of all the masts and sails and use a winch wooden wheel to drive them. At that time, it would have required fifteen or sixteen people to climb up and down, pulling back and forth, and the complex action of pulling back and forth would have been completed by only seven or eight people on the winch of the general assembly. Similar to the rudder operation, it is more convenient and fast. ”

Fang Zi'an looked at Liu Lao in a daze. He understood that Liu Lao was designing a control console with integrated control, although it was a mechanical winch operation, it was more efficient and convenient. This is extremely important during sailing. In fact, it is already a semi-mechanical, slightly more complex means of manipulation and transmission. Fang Zi'an didn't expect that Old Boss Liu would have such powerful thoughts and thinking.

"So this is a treasure old man." Fang Zi'an thought excitedly.
