It only took one day for Hong Tao and Wen Qi to make the model of the ship he wanted to build, which was very beautiful and light, and it also made Wen Qi scratch his head. Because he had never made a ship of this scale, he had to hold the model and ask his grandfather.

"Why do you have a piece of upright wood at the bottom of the ship?" Craftsmen have a common problem, that is, they are curious about the same craft, extremely curious! If he doesn't understand it, he won't be able to eat and sleep. Wen Lao Er originally didn't look down on Hong Tao, a foreigner, and he didn't plan to meddle in Hong Tao's shipbuilding affairs, so he let his youngest son help, which was already a big face for Huang Haitian. But not long after he saw this model, the old man changed his previous thoughts, this strange-looking boat made him feel both reasonable and unreasonable, there was always a hazy feeling, and he would not be practical if he didn't ask clearly.

"This is the type of ship from our hometown, which is suitable for sailing on the open sea, and I don't know why." What is the situation of the Wen family, and whether it can be drawn into its own interest group in the end, it is still unclear, and Hong Tao will not tell it clearly. This kind of thing called the stability plate has a proportion and weight limit, if you don't know the clear proportion, even if you install it, it will not play a corresponding role, maybe it is still a burden, so Hong Tao is not afraid of others to imitate. At this point, it is very similar to the principle of Wen's family model ship drawings, just look at it, and you are not afraid to imitate!

"This kind of plank must be a hundred-year-old wood, very expensive, and it will be wasted on such a small boat!" Huang Hai conveyed Wen Laoer's meaning again.

"Don't be afraid, you can pay as much as you want!" Hong Tao felt that this Wen Lao Er was playing tricks with him, and he would use the price to pressure himself without telling him the data of the stable board, buddy is rich! More than 100 times! With rolling hooks, ground cages and crab pots, money will continue to pour in, and if you can't build a 40-foot boat, you can't make a 20-foot boat?

"Tao Lingzi, Wen Bo said, the hull of this ship is too thin, the partition board has to be dense, and it needs to be made of good oil vertebral wood, which costs 70 yuan!" Huang Hai and Wen Lao Er chatted for a long time, and finally gave Hong Tao an offer.

"Uncle Huang, will he trap us?" Hong Tao felt that 70 guan was a bit much, and the small wooden boat of the Tanjia rocking oar was also four or five meters long, only about 30 guan. My ship is more than six meters long, in addition to the keel, stabilizer plate, mast requirements are relatively high, and there is no need for any big materials, how to double the cost.

"No, the Wen family won't do such a thing, you get what you pay for! He says the thinner your boat is, the more good wood you need. Look at the wood he piled up on the shore, some of them were bought by his grandfather from Li Min in the mountains when he was young, and they will be used for a few years or even more than ten years. Big stuff is even rarer, so the price will be more expensive, or build two pointed boats. Huang Hai trusts the Wen family, but he is also a little wary of the price. For 70 yuan, you can buy more than 30 stone of rice, which is enough for an adult to eat for ten years.

"Build one first, if it succeeds, we will have a better life in the future, believe me!" The 70 yuan is not Hong Tao's alone, the cooperative, everyone has shares, and he can't have the final say.

"Tao Lingzi, if you say this, I have no place to put my old face, you earned all this money, you can spend it whatever you say!" Huang Hai was afraid that Hong Tao would be annoyed, so he hurriedly expressed his attitude, although 70 yuan is a lot, but compared with Hong Tao, he can still calculate the severity.

After setting the price and model, it is time to choose the right wood to start building, Wen Lao Er said that he wanted to use oil vertebral wood, Hong Tao didn't know what this oil vertebral wood was, anyway, he hadn't heard of it, those timbers were all old wood that had been stacked on the shore for several years, and there were no leaves, and they couldn't be identified. However, Wen Lao Er said that the high-quality oil vertebral wood is not deformed, corrosion-resistant, and is a very good shipbuilding material, so Hong Tao is relieved, and he follows Huang Qi to work in the wood pile every day. Although he doesn't know how to work as a carpenter, he is a good hand and has a strong body.

"Uncle Huang, you go back and pick up that guy from the Great Qin Kingdom, the ransom I helped him pay, he should help me work, rightfully so! He also doesn't know how to fish, so it's inconvenient to put it at home. After moving wood for a day, Hong Tao remembered that he still had a slave, so he didn't have to use it in vain!

So, the beach on the west side of Zhenzhou Port became lively, a Han people, a Daqin people, and several Tan family members were busy from morning to night, in addition to the Tan family dialect and Chinese dialect, from time to time there could be a few grunts of ancient Latin and ancient German. The children of the Tan family in the neighborhood came here to see the Western scenery when they had nothing to do, and by the way, they commented on where the big rat's head on Hong Tao's back was sacred, why it could be tattooed so exquisitely, what kind of paint those lines were painted with, and why the colors were so bright.

This keel is probably the one that Wen Lao Er and Wen Qi brothers have done the hardest, it is not a strip, but a plate with two pointed ends and a protruding middle, which looks a bit like a kitchen knife for cutting meat. The six partitions are embedded in the top of this keel, and the two ends must not only be bent, but also have a slightly contracted arc inward. Just for this pattern, Hong Tao had to add another ten yuan to Wen Laoer, because it was too laborious to make the partition board like this, and it was necessary to steam the wood and fix it with a wooden wedge, bend it little by little, and it would take six or seven days to take shape.

It took 25 days for this keel to finish the partition board, and when it was time to lay the auxiliary keel, Hong Tao had another moth, and he had to use two more long auxiliary keels at the position of the waterline on both sides, and he had to protrude the hull and tie it wide. Wen Lao Er stared at the red eyes and quarreled with Hong Tao through the Yellow Sea interpreter, and personally took a small boat to Zhenzhou Port to take a look, and then reluctantly agreed with Hong Tao's idea and installed these two strange-looking auxiliary keels.

This is not Hong Tao's whim, this thing is called a shake keel, also called a terrier water wood, in fact, it has been used in the Great Song Dynasty, and Luo Youde's big bird boat has it, the purpose is to reduce the side swing of the ship and increase stability. Don't underestimate the protruding wide wooden edge, the actual effect is very obvious, and many ships in later generations are also using this technology. Maybe at present, this technology is not particularly widely used, such as Wen Laoer's private small workshop has not yet learned, the general high-tech should be in the Great Song Dynasty in the national construction shipyard, where the craftsmen are all drawn from the whole country, not only the southern shipwright, but also the northern Dengzhou side of the boatwright, after the integration, it is easy to invent new technology.
