Chapter 1940: "The most advanced in history"

In order to ensure the confidentiality of Cork Port and the possible appearance of ships of other countries on the Cork Port to North America route, Marin decided to station a fleet of 10 warships in Cork Port.

Just use a 250-level armed merchant ship, but all equipped with 20 artillery, instead of just a few artillery like the merchant ship. As soon as a vessel attempting to approach this route was found, the gun was fired immediately. If you do not listen to the warning, sink it.

Marin estimated that the six Calais ships in France are now almost fighting. Maybe they will take the initiative to provoke provocation. Marin did not want to interfere in the battle between the Calais and the British Cork, but he would never allow those Calais to be near Cork and the route from Cork to North America.

In the future, Marin also intends to station a fleet of 20 warships in Port Cork to cruise the southern waters of the Cork port to North America route. In addition to preventing foreign ships from seeing flying shears, there are also French ships and commercial ships that venture to North America.

Historically, the French's adventurous merchant ships went to the Canadian waters. Moreover, they are often actively involved in the **** skin trade in Canada.

In fact, the latitude of France and Canada are basically parallel. French merchant ships can reach the east coast of Canada as long as they travel straight west on the Atlantic Ocean.

It is also interesting to say that the latitude of France is obviously very high. It is the same as the latitude of eastern Canada and northeastern China. However, France is a warm area, but Canada and the northeast are bitter cold places.

This is related to the influence of ocean currents. Because of the influence of the North Atlantic warm current, although the British and French latitudes are very high, they are warmer than Northeast China. The situation on the Canadian side is more complicated. It is divided into two situations-Newfoundland as the dividing line. The north side is affected by the Labrador cold current, and it has a cold climate that is just as good as the northeast. On the south side of Newfoundland, it is relatively warmer due to the warm current branch of the North Atlantic Ocean (the trunk is biased to the east and crooked to the European side). The confluence and collision of warm currents and cold currents also formed the Newfoundland fishing ground on the east side of Newfoundland. Similarly, the Hokkaido fishing ground was also formed after the confluence of the Japanese warm current and the Qiandao cold current.

Fortunately, Marin carried out malicious demonization propaganda on the Americas, so that the current Europeans do not have a cold for the Americas. But in the end, the paper cannot cover the fire. Just like this time, the French will send people to the Delaware Peninsula to investigate, forcing Marin to ask Kahn to play orcs.

Marin has been dragging the French now, preventing them from going. Kahn, they have already practiced almost, and are ready to go to the Delaware Peninsula to familiarize themselves with the venue, and practice there many times. When the people dispatched by France arrive, they can play on the spot.

In any case, after this time, Frenchmen who have been to the Delaware Peninsula can feel the climate of North America. Despite the intimidation of the orc drama, I am afraid that the French will not stop the determination to take risks. After all, Marin can find the Delaware Peninsula and resist the attack of the "orcs" by building the Great Wall. Why can't France?

Even if only a few people dare to take risks, and most of them are personal behaviors, it is worth being vigilant. Therefore, in the future, Marin intends to deploy 40 warships in Port Cork to fully patrol the west coast of France. As long as a vessel that wants to go west to the Americas is found, once it is far from the French coastline, it will sink ruthlessly. Then, all the Frenchmen on board were killed without leaving alive.

As long as it is far away from the French mainland and does not leave a live mouth, the French want to make trouble, Marin can also push two or five, and throw the pot to the legendary "pirate" ...

...

In order to successfully build a flying shear boat at this new shipyard in Cork Harbor, Marin selected a group of capable shipbuilders from the local Emden shipyard and moved to Cork Harbor Shipyard, which is responsible for flying shear Shipbuilding.

Marin has "designed" the drawings of the flying shears and made them into patterns. Including the bow must be hollow, also marked out.

It should be pointed out that the flying shears “designed” by Marin are very different from the original flying shears. Most of the original flying shears used full-scale sails, that is, the horizontal sails were the main ones, and the vertical sails were the second ones. In this way, the flying shear boat will not be able to drive when it encounters upwind.

Of course, that was an early flying shear. By the 20th century, in the later period of flying shears, the upper edge slant sails were basically used uniformly.

Previously, when Marin converted a 250-class armed merchant ship, he made people study the upper edge skewer sail and fin stabilizers. Moreover, they have been studied.

Now, it is just right to apply the technology of upper edge slant sail and fin stabilizer to the flying shear ship.

After using these two technologies, Marin's flying shears will surpass the "Wyoming" in the early 20th century and become a fast and stable flying shears.

You know, the flying shear ship reached its peak in the early 20th century. Although they are very fast, for example, the 6-mast flying shear ship "Wyoming" with a displacement of up to 9100 tons, the downwind speed can reach 16 knots, and the headwind can also reach more than 10 knots, which is very fast. However, because the hull is too "weak", and a large number of longitudinal sails are used, the hull is subject to strong lateral wind.

Fortunately, it is easy to roll over and overturn once it encounters a storm. At the beginning of the 20th century, several shipwrecks of large schooners rolled over continuously. At the same time, due to the steady progress of the power of steam engines and diesel engines, flying shears have withdrawn from the stage of history.

But in fact, anyone who is familiar with the history of navigation knows that flying shears are out of luck. Because, after the flying shear ship withdrew from the historical stage, an artifact that made up for the shortcomings of the flying shear ship was born, that is, fin stabilizer ...

The concept of fin stabilizer was proposed in 1889 and was also patented. However, it wasn't until 1923 that Japan's Yuanliang Shintaro designed the first set of fin stabilizers for use on ships. Then, in 1935, the British also applied fin stabilizers to ships. Since then, fin stabilizers have been widely used.

In later generations, almost all ships with faster speeds were equipped with fin stabilizers. Because, the warships of later generations, the aspect ratio is much more exaggerated than the flying shears.

The 6: 1 aspect ratio of the flying shears is already very "thin". However, the 052 destroyer of his next generation, with a length of 142.7 meters and a width of 15 meters, the aspect ratio is almost 10 to 1, which is very exaggerated.

Of course, the destroyers of later generations have several pairs of fin stabilizers. At the same time, it is also powered by machinery, without using the more dangerous vertical sails, and it is not easy to roll over.

For the flying shear ship that Beihai intends to build, Marin prepared three pairs of very original fin stabilizers, which are manually controlled. Although it lags behind the fin stabilizers of later generations, it has greatly increased the safety factor of flying shears.

The flying shear boat without fin stabilizers is almost "staggering" on the sea. The presence of fin stabilizers can make the high-speed flying shear ship much more stable, greatly reducing the chance of overturning.

Moreover, as a means of conveying news and transporting precious materials in the North Sea, Marin also plans to install four 12-horsepower single-cylinder diesel engines at the stern of some flying shears. Once encountering a storm, the flying shears will lower the sails and rely on the power of the diesel engine to withstand the storm. Wait until the storm has passed before using the sail again. In this way, the safety of flying shears has been more improved.

Of course, only the passing of important military conditions, and the small number of flying shears that carry precious materials under Marin ’s command, are eligible for diesel engines. After all, there are not many diesel engines in Marin's hands, and the mechanical type that can manage and maintain the diesel engines is lacking ~ www.wuxiaspot.com ~ And equipped with several mechanics, responsible for the management and maintenance of diesel engines.

After using the upper edge slant sail, fin stabilizers, and equipped with spare diesel engine power equipment, Marin's flying shears, dare to claim to be "the most advanced" flying shears in history. This is compared with the original flying shears in the era of flying shears, not compared with the ships of this era. Because the level of ships in this era is really too backward. Compared with them, Marin's new flying shears won even if they won. Only compared with the authentic flying shears of the 19th and early 20th centuries, the evaluation of the "most advanced" flying shears in history is valuable ...

Because the average speed can be three times faster, this means that whether it is to convey military sentiment or to transport precious goods from Daming, the speed will be three times the original. Originally it took two round trips in two years, and it only took more than half a year to get it done. Moreover, because of the use of "the most advanced" technology, its safety is also much higher than the original flying shear ship.

With the greatly shortened travel time, Marin's ability to control the American colonies can also be greatly enhanced. In the past, it took more than four months for ships to travel between North America and the mainland. Today, more than a month is enough to run back and forth ...
