The opening kaleidoscope writing wheel eye: the war on the top

Chapter 290 Zigzag Navigation

After listening to Merry's professional explanation, Hanan half-understood, thinking it would be better for Jessica to listen, so he hurriedly boarded the boat with Merry.

After boarding the boat, Hanan was still looking around curiously. The width of the deck was about nine to ten meters. The bottom of the mast was full of ropes, and the hard sail with bamboo ribs was folded at the bottom of the mast.

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

At this moment, Jessica came over and asked Melly, "Why is the sail of this boat so strange?"

Melly smiled and replied: "It must be different from the soft sails you often see. This is a hard sail."

Jessica exclaimed in surprise, "Ah, I've only seen it in the history of the development of sea ships, no wonder it looks familiar, but this is the first time I've seen the real thing."

Although the ships of Qiao and his elves were older, they had always used soft sails. When they saw the hard sails, they were also very surprised, and asked, "What's the difference between the hard sails and the soft sails?"

Just as Melly was about to answer, Jessica said first: "I have learned before that hard sails and soft sails have their own advantages. Hard sails are relatively easy to make and do not require high materials.

Ordinary fabrics are fine, and in an emergency, even straw mats and reed curtains can be used instead. Even if the sail surface is slightly damaged, it can still be used, and temporary repairs are also very convenient. "

Mellie looked at Jessica in surprise. She didn't expect that this girl was not only beautiful, but also knew a lot about ships.

Jessica continued: "Actually, the most important advantage is that it can rotate around the mast, making the sail surface more efficient in receiving wind. There is even a saying that a hard sail can use wind from eight sides.

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

Meli nodded and added: "That's right, it's especially suitable for a small team like yours. It's extremely easy to operate, and doesn't require frequent adjustments, saving manpower. Have you noticed?"

Pointing to the mast, he continued: "This kind of sail has no pulley block, and no complicated sail cables and rigging, and ordinary people can do the work of retracting and retracting the sail.

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

While talking, Meili showed a demonstration, tried to raise his hands, but remained motionless, panting: "This sail has ribs inside, although it is made of wood.

But the number is large, so the weight is very heavy. Not to mention a lot of manpower is needed to hoist the sail, and a strong person is required to control it. "

Charlie walked over with a limp, and tried it out. He was not an ordinary person after all. Although it was still a bit laborious, he lifted it up smoothly. He turned his head and nodded at Hanan, indicating that it was completely controllable.

Hanan felt relieved when he saw this, and Melly stared wide-eyed, still surprised by Charlie's brute force, but Jessica continued, "But there is a fatal flaw, the price of a hard sail is that it is too heavy and restricts In order to determine the carrying capacity of the ship, the key is to increase the speed. Compared with the soft-sailed sea-going ship, it is definitely far behind."

Meili nodded, and said, "That's right, it's a big problem to convert it into a soft sail, and it may only be solved in the capital of seven waters."

However, Hanan smiled mysteriously at everyone: "This is not a problem at all for the time being."

Jessica is very confident in her sailing knowledge, just when she was about to say something, Hanan interrupted: "Let's not talk about this, let Melly introduce the others."

Jessica looked at Hanan 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 know that there is also the ingenious design of watertight bulkheads. There are ten lines in the entire hull, mainly for..."

When Hanan heard this kind of technical terminology, he couldn't understand it at all, so he quickly said to Melly, "Just tell Jessica about this, it sounds like a headache to me."

Jessica chuckled, thinking that there are times when you can't do it, so she proudly discussed it with Melly.

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

Jessica was pleasantly surprised, and then asked Melly, "Then tell me, what other good things are there on this boat."

"I told Hanan just now that the water board has another magical effect. It can be used in combination with this hard sail and rudder to allow the boat to sail in all wind directions."

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

An hour later, Jessica was finally satisfied and let Mellie go with a happy smile. Charlie couldn't wait to cling to Mellie again. It turned out that he was asking about artillery equipment.

"The bow and the stern each have a fixed gun emplacement. Because this ship is more adventurous, there is only one gun port on the side. In addition, there is a movable cannon on the deck," Meili pointed to the deck. In one corner, there was a big guy, wrapped in a big oilcloth.

Charlie rushed away impatiently, and Melly shouted at Charlie with a smile: "Attention, when you fire a cannon on the deck, it must be installed on a fixed track. The hardwood at the end of the track can counteract the recoil. !"

Charlie studied the artillery for a while, and said disappointedly: "This artillery is not very good, and the range must be insufficient."

"I can't do anything about it. I only know how to build ships, but I'm not good at casting cannons. Just these few were purchased with great difficulty a few years ago. If you want to buy new ones, you can only go to big towns to look for them.

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

Suddenly, Charlie realized that he was busy on his own, and Joe found Merry again, and wanted to ask him to take him to the cabin to have a look.

Hanan stood by the railing on the side of the ship, the voices of his friends kept echoing in his ears.

This voice represented happiness, excitement, and even happiness. Looking at the endless sea, Hanan silently said in his heart: "Great route, here I come!"

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

Hanan suddenly raised his head to look at the sky, his eyes seemed to span time and space, he opened his mouth silently, as if he was talking to another person, he shouted in a voice that only he could hear;

"Don't worry, I'm already on my way home!"

At the same time, on the warship, the sailors were busy, waiting for the commander's order, and then fired bombardment at the unidentified incoming ship.

Suddenly, a black shadow shot out from the sea, the sailors on the deck were startled, and then there was a commotion, staring blankly at the person coming.

The black figure was still in the air, and he snorted coldly, "Water gun!"

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