When Huangshi contacted the manufacturer, he heard the manufacturer's sales manager telling some clichés about their products that are lightweight and high in strength, and mentioned that they can produce carbon fiber masts of different specifications and shapes according to customer requirements. The length of carbon fiber masts produced can reach up to 16 meters.

In general, it is low cost and short manufacturing cycle, so Huangshi asked, "Can you still customize a 16-meter-long mast?"

"Yes, Boss Huang, we not only produce cross-truss and struts, but also produce this mast. Our products have reasonable overall structure, easy storage and handling, and simple switching. Moreover, all products, with a surface package of 3K or electroplated colored glass fibers, can be used."

When I heard the sales staff of the manufacturer say this, Huangshi, which originally only planned to replace the cross-truss and struts, had his eyes shining, and I thought that the mast as thick as a bowl could be replaced.

"It's 16 meters, it seems that my sea boat is not available." Huang Shi thought so in his mind. Although he had not measured the height of the mast in detail, he had visually measured that the main mast was only about six or seven meters high.

In terms of mast height, it is also another obvious difference between Chinese sailboats and Western sailboats. The masts of Chinese sailboats are far lower than those of Western ships in height, so the requirements for mast strength are not as strict as those of Western ships, and they must be strictly fixed with dense ropes.

The masts of Western sailboats are generally composed of three or two independent masts through masts. The masts are towering, and some even reach 3/4 of the length of the hull. Later warships also have additional wing sails. The area of ​​sails that can be suspended will far exceed that of Chinese sailboats, so their advantage in speed is also significantly better than that of Chinese sailboats.

The masts of Chinese sailboats are generally only 1/5 of the length of the hull. The most intuitive example is Zheng Chenggong's "three-masted gun ship". This kind of ship is a large lucky ship. Its data is "three masts in the tree, the main mast is 4 zhang high, the length of the ship is 20 zhang, the cabin is five floors, the surface of the ship is as high as a city, and it can accommodate 300 people." That is to say, its length is 67 meters, the mast is only 13.3 meters, and it is equipped with 8 Red Cannons and 40 Qianjin Folang Machinery.

The largest warship in the West during the same period was the "King of the Sea". It was built by shipbuilder Peter Pett in 1637 during the reign of King Charles I of England. Its data is that its displacement is 1,500 tons, its length, including the bow splint, the total length, the main mast is 35 meters high, the draft is 5 to 6 meters, and the speed is 10 knots. In terms of military equipment, there are 104 cannons, including 20 60-pound cannons, 8 30-pound cannons, 32 18-pound cannons, 44 9-pound cannons, and the crew is about 800.

Therefore, although the "three-masted gunship" is only less than 4 meters narrower than the "Sea King", the height of the mast is nearly twice as low, so its data in various aspects is also much worse.

So after a brief consideration, Huangshi customized two masts from this manufacturer, one 15 meters and the other 10 meters, namely the main mast and the rear mast.

...

After waiting for a few days, the manufacturer sent the masts, trusses and struts to the shipyard, and Huangshi took them together with the Oxford-spun sailing fabric to Dongluo Island.

Huangshi asked Hong'er to select a few people from the servants who were good at Hong's eldest daughter in Jiangjiazhuang, and asked them to sew the cross truss and straps to the sail surface with special silk threads. Later, they called Zhu Mingxin, Wang Luobin, Zhan Wuya and other carpenters to come.

"Chief, are you looking for us?" Zhu Mingxin and the others were building several wooden racks at the time. When they heard that the chief was called up for something, they hurriedly brought the tools and rushed over.

Huangshi pointed to the two masts on the sea boat and said, "You three think about how to replace these two masts for me."

"Yes, Chief."

Zhu Mingxin, Wang Luobin and Zhan Wuya only noticed that there were two dark tall poles on the ground, about 3 or 4 meters long.

"Chief, let's call a few more people to come and help." Zhu Mingxin and the others saw that the pole was very long and thick, and black, and thought it was made of fine iron, so they wanted to find some people to come and carry it onto the boat together.

Huangshi didn't know their concerns, so he nodded and agreed, "Go."

When they called people back and stood next to the main mast as big as a blue ball, Huang Shi realized that it was like this and said, "Mingxin, this mast made of lightweight carbon fiber composite is very light. You should not call so many people to come."

Seeing that he seemed to be a little suspicious, he continued, "Haha, if you don't believe it, you can lift it up any one of you."

"Hehe, Chief, then I'll try it." Wang Luobin touched his head and said with a smile to Huang Shi.

"Okay, you can try it."

Wang Luobin walked to one end of the main mast. Although he had just heard from the leader that he could lift it by just one person, but after all, hearing it is weak and seeing it is solid. So when he was sinking, he took a deep breath in secret, then held the pole in both hands, trying to exert force to lift it up, but he didn't know that he exerted too much force in an instant. The pole was light and fluttering like a bamboo pole. The person suddenly leaned back and fell down his butt.

"Chief, is this kind of pole strong?" Wang Luobin stood up rubbing his butt, ignoring the people laughing beside him, walked to Huangshi and asked him.

Because in his understanding, the heavier the mast, the stronger it will be. The pole like the leader brought now is so light that it is floating. If it stands on the boat to make a mast, will it be blown off when the strong wind comes?

Huang Shi almost laughed out loud just now, but he still suppressed his smile and replied, "Lobin, don't worry, this pole is also used as a mast in the upper world, and it is even used on the 'aircraft' and 'rocket' that I told you about. You don't have to worry about the strength."

"Airplanes, rockets also use them?" Wang Luobin and the others widened their eyes. These two things had been mentioned by the leader before, saying that they were "magic weapons" that could fly in the sky. Even mortals like them could ride on them and fly over the blue sky and white clouds, like immortals, which was extremely envious.
