Opening Mangekyō Sharingan: War On The Top

Chapter 290

After listening to Melly’s professional explanation, Yu Nan seemed to understand, thinking it would be better to let Jessica listen to it, and quickly boarded the boat with Melly.

After boarding the ship, Yu Nan was still looking around curiously. The deck was about nine to ten meters wide. The bottom of the mast was covered with ropes, and the rigid sails with bamboo ribs were folded at the bottom of the mast.

Yu Nan took a closer look at the mast and sails, and always felt something was wrong.

At this moment, Jessica came over and asked Melly: “Why is the sail of this ship so strange?”

Meli smiled and replied: “It must be different from your usual soft sails. This is a hard sail.”

Jessica cried out in surprise, “Yeah, I have only seen it in the history of the development of sea ships, no wonder it’s a bit familiar, but it’s the first time I have seen it in kind.”

Although the ships of Joe and the Elves are older, they have always used soft sails. At this time, they were surprised when they saw the hard sails, and asked, “What is the difference between the hard sail and the soft sail?”

Just as Meli was about to answer, Jessica preemptively said: “I have learned before that hard sails and soft sails have their own advantages. Hard sails are relatively easy to make, and the requirements for materials are not high.

Ordinary fabrics will do. In an emergency, even straw mats and reed curtains can be replaced. Even if the sail surface is slightly damaged, it can continue to be used. Temporary repairs are also very convenient. ”

Melly looked at Jessica in surprise. She didn’t expect that this girl was not only pretty, but she also knew boats well.

Jessica continued: “In fact, the main advantage is that it can rotate around the mast, making the surface of the sail more efficient in receiving wind. There is even a saying that a hard sail can use wind from all directions.

Even in the face of an oblique headwind, the angle of the sail can be adjusted at any time to make the ship sail in a zigzag pattern, which is not possible with soft sails. ”

Meili nodded and added: “Yes, it is especially suitable for small teams like yours. It is extremely easy to operate, and does not require frequent adjustments. It saves manpower. Have you found out?”

He pointed to the mast and continued: “This type of sail has no pulleys, and no complicated sail cables and rigging. Ordinary people can do the work of retracting and unwinding the sails.

And the speed is very fast. When you are in danger, you can even cut off the main rope in a few seconds, but it takes more effort to raise the sail.”

Meli said, and gave a demonstration. He tried to raise his hands, but he didn’t move at all. He panted, “This sail has ribs in it, although it is wooden.

But the number is large, so the weight is very large, not to mention the manpower required to raise the sail, and the strong man can control it. ”

Charlie walked over and tried again. After all, he was not an ordinary person. Although he still had a little effort, he lifted it smoothly. He turned his head and nodded at Yu Nan, indicating that he was completely controllable.

When Yu Nan saw this, he relaxed. Meli’s eyes rounded, still amazed by Charlie’s brute force, but Jessica took the conversation, “But there is a fatal flaw. The price of a hard sail is too much weight and restrictions. The key to improving the ship’s carrying capacity is that the speed cannot be raised. Compared with the soft sail boat, it must be far behind.”

Meli nodded and said, “Yes, if you want to convert it into a soft sail, it’s a big problem. It may only be solved in the Capital of Seven Waters.”

Yu Nan smiled mysteriously at everyone: “This is not a problem at all for the time being.”

Jessica is very confident about sailing knowledge. Just about to say something, Yu Nan interrupted and said, “Don’t talk about this, let Melly introduce the others.”

Jessica looked at Yu Nan strangely, and swallowed the words that came to her lips.

“I have learned a lot from the design drawings of this ship. For the first time, I knew that there is also the ingenious design of watertight bulkheads. There are ten channels in the entire hull, which are mainly used for…”

When Yu Nan heard this kind of professional terminology, she couldn’t understand it at all, and quickly said to Melly: “Just tell Jessica about this. I’m a headache.”

Jessica chuckled, and talked about it triumphantly with Melly when she thought that your kid couldn’t do it.

“This watertight bulkhead increases the structural strength of the hull and can strengthen the hull.”

Jessica was surprised, and then asked Melly: “Then tell me, what other good things are on this boat.”

“I just told Yu Nan that the drape has another magical effect. Using it in combination with this hard sail and rudder can make the boat have the ability to sail in all wind directions.”

Jessica kept asking Meli questions, and Meli answered them patiently.

An hour later, Jessica was finally satisfied, letting Melly leave with a smile, and Charlie couldn’t wait to stick Melly on, it turned out to be asking about artillery equipment.

“The bow and the stern each have a fixed gun position. Because the ship is inclined to explore, there is only one gun window on the side. In addition, there is a movable artillery on the deck.” May used her finger to point to the deck. In a corner of, there is a big guy, wrapped in a big tarp.

Charlie rushed away impatiently. Melly smiled and shouted at Charlie: “Attention, fire on the deck and install it on a fixed track. The hardwood at the end of the track can offset the recoil. !”

Charlie studied the artillery, and was disappointed: “This artillery is not very good, it must have insufficient range.”

“I can’t do anything about this. I can only build ships. Casting guns is not good. These are only a few years ago, and they were finally purchased a few years ago. If you want to replace them, you can only find them in big towns.

And better ones can only be bought on the black market. ”

Charlie suddenly realized that he went to Busy Green, and Joe found Melly again and wanted him to take it to the cabin for a look.

Yu Nan was standing by the guardrail beside the ship’s gunwale, and the voices of his friends kept echoing in his ears.

In this voice, it represents joy, excitement, and even happiness. Yu Nan looked at the endless sea and said silently in his heart: “Grand Line, I am coming!”

At this time, Jessica walked to Yu Nan, with a sweet smile on her face, and whispered to him: “Yu Nan, with this boat, we can finally set off and find that place!”

Yu Nan suddenly raised his head and looked at the sky, his eyes seemed to have crossed time and space, and his mouth opened silently, as if speaking to another person, he shouted with a voice that only he could hear;

“Don’t worry, I’m already on my way home!”

At the same time, the marines were very busy on the warship, waiting for the commander to order, they had to bombard the unknown incoming ship.

Suddenly, a black shadow shot out from the sea, and the marines on the deck were taken aback, and then there was a commotion, staring blankly at the incoming person.

The dark shadow was still in the air, so he heard a cold snort, “Water gun!”

As soon as the voice fell, there was a pop, and something suddenly spit out from his mouth, which flew out like lightning.
