Why, as a national naval division, its main combat power is all standard 400-material warships, and the reason is also incomprehensible to Li Tianyang, who used to be a layman. It wasn't until he went into battle in person and followed Li De and them through a few pirate journeys that he didn't get anything.

The 400-block ship, according to modern calculations, is about 230 tons of displacement. In the era of the Ming Dynasty, there are reliable records, except for the Zheng He's treasure ship, which no one knows about, and only hears its voice so far, and does not know where it is, the sea ships of more than 1,000 materials, with the shipbuilding technology of the Ming Dynasty, can indeed be manufactured, and there are even about 2,000 large ships.

This is what Li Tianyang has seen with himself, and he can't fake it.

In this way, the 400-material warship is really compared with those thousand-material sea ships, but in terms of volume, it is too different. But in fact, in terms of their practicality for naval operations, the two are much smaller than larger. Of course, we are talking here about our Chinese shipbuilding technology, not European shipbuilding technology of the same period.

In the shipbuilding industry of the Ming Dynasty, in the ocean trade, eight or nine times out of ten are actually based on lucky ships, among which the advantages, the first tip is conducive to breaking the waves, the bottom tip can reduce the resistance of the seawater, and the draft depth can help the shipowner to transport more goods; At the same time, as the advantage of hard sail manoeuvre, it can maximize the use of wind power and reduce the difficulty of personnel to operate the sail. Because the hard sail can rotate 360 degrees, this means that the wind blowing from any angle will adjust the angle in time to match.

However, relatively, the larger the ship, the area of the hard sail that it needs to be equipped with will increase accordingly, and in the Ming and Qing dynasties, the hard sail is mostly made of bamboo strips, straw mats and the like. This means that the area of the hard sail should not be too large from the beginning, because the larger the sail, the heavier its weight, so there is the so-called two-masted, three-masted and other sailing ships.

However, this method can only treat the symptoms, not the root cause. That is to say, the larger the ship, the slower its speed will be, because the sail area is not enough, resulting in insufficient wind surface of the sail, which makes the thrust insufficient.

As the first choice of pirates and sailors, the requirement for speed is the first consideration in their hearts. If you can't even catch up with a sea ship, then as a pirate, it is really a failure, and if a huge warship can't keep up with the speed of the pirates, and can't ensure the safety of the surrounding seas, the sailor and the rock wool face many maritime groups with deep backgrounds!

In terms of flexibility, there is no need to say anything more. If you want to make a U-turn, you need to make a big turn, which takes more than twice as long as a small boat in terms of a simple sailing distance.

In the same way, as the top technology of the Ming Dynasty at that time, the watertight compartment technology created the risk of water leakage and sinking of the ocean-going ships of the Ming Dynasty, and with it, the decline of the firmness of the hull. Although the Ming Dynasty also had a remedy, such as the 400-material battle seat ship, the double-bottom structure was used to strengthen the thickness and solidity of the ship's walls, but it also reduced the internal volume of the hull and increased the cost of shipbuilding, which was a technology that merchant ships would not adopt.

(Of course, there are many reasons for the main position of the Ming Dynasty's four hundred warships, so I won't say much here, if you like this buddy, you can go to Baidu.) I'm only a half-ass, so I won't be ugly here, lest there be buddies who like to specialize in research to pick out thorns. ）

Therefore, in the coastal area of the Ming Dynasty, whether it was pirates or sailors, in fact, most of the warships were about 400 lucky ships, or other sea ships were transformed. To sum up, in the choice of sailor and pirate car, speed is greater than flexibility, and flexibility is greater than sturdiness, and finally the size of the space inside the hull will be considered.

And the centipede ship is the most outstanding pirate ship that Li Tianyang has seen over the years, and it is also the reason why he took a big risk to get his hands on it.

Although it can only reflect the dim moonlight, it is not difficult to find that this is an excellent sea ship. The narrow hull alone tells you how fast it is from simple physics.

The length is about ten zhang, but the width is only a little more than one zhang, such a design, from the beginning to minimize the resistance of the seawater, although these are at the expense of most of the storage space inside the hull; However, the speed advantage that comes with it makes it difficult for any target it targets to escape its clutches. Whether it is tracking prey or escaping the pursuit of the sailor, Li De has been proud of all these years.

Since obtaining this centipede ship, Li De spared no effort to renovate and upgrade it, with two masts about three feet high in the middle of the hull, and hundreds of oars stored between the walls of the ship on both sides, whether it is downwind or upwind, the speed of the ship can be guaranteed to be above a very fast standard, which is convenient for pirates to seize the upper hand, or escape from the search of the sailor warship as soon as possible.

The front and rear of the hull are pointed heads and sharp tails, which can allow the hull to quickly change direction without turning the rudder in a critical situation, which is a huge advantage that no other ship can match. This makes the already streamlined centipede ship a lot more flexible than other ships.

Of course, there is another point, the centipede ship was originally a Dutch ship imitated by the Ming Dynasty dockyard in order to fight pirates and pirates. At that time, this can be said to be an outlier in the shipbuilding industry of the Ming Dynasty, which mainly focused on carrying capacity; Correspondingly, the sturdiness of the centipede ship is not up to the level of European ships, but compared with the vast majority of sea ships in the Ming Dynasty, it can even be used as a collision angle in the sea, directly knocking out a big hole in the wall of an ordinary lucky ship, without the slightest damage to itself.

At that time, the Ming Dynasty sailors only made a batch of centipede ships in the Jiajing period, and made a lot of contributions to the Ming Dynasty's great cause of resisting the Japanese, and even made great achievements in the famous Battle of Lianglu in Korea. However, in the Wanli period, I don't know why, but the sailor took the initiative to give up this water weapon; It's just that this shipbuilding technology, in the end, still went to the people, was preserved by the masses, until the end of the Qing Dynasty, was transformed into a 'fast crab' ship, shining brightly.

Of course, this is a later story, as for where Li De got this centipede ship, it can be regarded as a secret between their adults, and it is not known to outsiders. However, with the current net worth and power of Li De's team, there is only such a centipede ship, and the preciousness of it can be imagined. If it weren't for the fact that he was going to come back for Halloween before the first day of the seventh month, he might not have been able to see a long-distance sea ship within a radius of dozens of miles, and Li De might not have driven the centipede boat back to the village.

You must know that this centipede ship itself is named after Li De's nickname, and the ship is called 'Crazy Shark'. Now in the Qiongzhou sea area with a radius of hundreds of miles, the legend of this thief ship is even broader than Li De himself, and it can be said that this is also a business card of his Li De. If it is discovered that this sea ship is now docked outside Tanmen Village, as long as you are not stupid, you can also think of the famous wild shark, and there must be an extraordinary connection with a small Tanmen village.
