Chapter 123 Ten Boat Speeds

A day's test voyage finally ended when it was dark. Yu Xiaotian returned to Nanri Island with a ship and was surrounded by ships into the bay.

The craftsmen who couldn't catch up with the ship to go to sea to test the water have been waiting here for a long time. As soon as they saw the ship's complete return, they all rushed to the shore to welcome them.

The ssam towed the new ship again, towed it near the dock, and handed it to the people on the shore to slowly tow the ship back to the dock again.

After a day of testing, the shipmen did not dare to be careless. They quickly boarded the ship and conducted a careful inspection of the ship from beginning to end to see if there were any problems with the hull structure and whether there was any leakage.

Even if such a situation occurs, it is normal. After a ship enters the water from a dry dock, the force of the hull changes dramatically. Some problems that could not be found before can be shown after launching and testing the water. Therefore, according to the conventional rules of this era, after a new ship is delivered, it must first The hull will be tested for a few days, and the hull will be thoroughly inspected. At the same time, all kinds of sails, rudder winches and other things on the ship will be inspected. It will not be delivered to the ship owner until there is no problem.

So here, everything is the same as usual. After a day of water testing, the new ship was immediately towed back to the dock for a major inspection inside and outside.

The next day, after another day of inspection, Guo Fu told Yu Xiaotian, "The big masters, the small ones of this new ship have been checked inside and outside. Except for a few seams of the boat that are somewhat leaking, the rest of the parts are very strong and no problems have been found!

I just don't know how the ship feels after the big owner takes people to test the water?

Yu Xiaotian nodded and said, "That's good! After I took someone to test the water yesterday, I felt that the overall performance of the ship was not far from the performance I wanted, and the speed had not reached the speed I wanted! The sails need to be adjusted, and the triangular sail in front can be completely enlarged! In this way, the speed of the ship can be increased.

In addition, the operation of the rudder is a little astringent, and there are a few points. It is a little difficult for the helmsman to pull the rudder. You can check it later and solve this problem.

And the rudder of the ship's rudder is a little longer, which can make the helmsman more labor-saving. The angle cannot be adjusted for the time being. If the angle of the rudder can be adjusted, the ship will be more flexible. So far, I feel that the ship has not fully exerted its performance!

In addition, the bottom of the ship is too heavy in front of the warehouse stone. When the bow runs up, it can't be raised, which also affects the speed. The horizontal shaking is a little big, which is not as stable as I thought.

However, on the whole, this ship is still good. At least in speed, there is no one out of our ship for the time being! In the next month, I will personally take the boat or ask people to go to sea to test the water every day, and try to find more problems. When the next ship is built and modified at the same time, when the next ship is caused neatly, I can basically solve the existing problems together.

Guo Fuyi wrote down the questions raised by Yu Xiaotian and promised to start checking and modifying immediately after Yu Xiaotian went back.

In the next month, although Yu Xiaotian could not take this ship out for trial every day, he would spare at least three or five days to take this ship out to try the water.

After a month, the performance of this ship was basically determined. This kind of sloop is indeed a very good boat type, with fast speed, simple operation, good flexibility, and requires a small number of sailors. It is not only very suitable for offshore navigation, but also Even in bad weather, it can maintain stability at sea.

But it can't be said that this kind of ship is perfect. The biggest problem just happened to be on the sail. Although Yu Xiaotian found a way to get a large number of Indian canvas from the Spaniards to meet the demand for sails of this new ship, because this kind of sail is relatively concentrated, this kind of Indian canvas is also heavenly. However, the material is made of cotton and linen, so the strength does not meet the requirements of Xiaotian.

After a month, during several trials, when the wind was full, the sails, especially the bow and sails, were torn, and they had no choice but to return to the island for repair.

At this time, Yu Xiaotian felt that he was still a little too optimistic. Although this kind of sloop is indeed a very good sailing boat, the problem of sailing equipment limits its performance.

If you want to solve it completely, this problem can only be completely solved if the chemical fiber fabric is invented to greatly increase the strength of the sail.

But chemical fiber fabrics can't be solved by him now. It requires a set of chemical technology to complete such a thing.

So at present, he can only thicken the force part of the sail to meet the current needs, and it is necessary to set aside a spare sail on this kind of ship. Once the sail is found to be torn, there is a set of spare sails for the people on the ship.

In addition to this problem, the ship basically gave full play to its characteristics after a month of water testing. However, due to the thickening and strengthening of the wooden structure of the hull, the dead weight of the hull has increased, which affects the speed of the ship to a certain extent. It has not been able to run at the speed that Xiaotian wanted, which is faster than he expected. It's lower.

However, even so, the speed of this ship has also made the sea wolf members very satisfied. Every time they go out for a trial voyage, there will be ships to accompany the new ship to sea, but every time they go to sea, as soon as the ship raises its sail, it will immediately break through the waves and leave the ship accompanying it to sea. I can't even smell it.

So the new ship soon got the nickname of flying on the water in the sea wolf. Every time it goes to sea to test sail, it will jump and cheer at the ship.

Later, Yu Xiaotian directly named the ship "Flying Fish" and used it as a test ship.

After testing the water several times to determine the safety of the hull structure, Yu Xiaotian ordered the ship to install four six-pound guns, two on the left and right sides, and a 12-pound short gun at the bow position for use as the bow main gun.

After installing the artillery, Yu Xiaotian first asked the ship to conduct a ttaining firing test at the seaside to check the strength of the hull under the vibration of the rear recoil of the cannon.

After the test gun was tied on the shore, the hull and internal cabin and other affected parts were inspected, and there was no cracking. Yu Xiaotian then asked the ship to go to sea for shelling tests.

After a test gun, Yu Xiaotian concluded that the ship was an absolutely strong guy. He ordered the sailors on the ship to fire two six-pound guns on the side of the side of the ship and the 12-pound short gun in the bow in one direction at the same time, and the ship successfully resisted the back seat of three guns. The force was just a huge earthquake on the hull, but it did not have a destructive impact on the hull structure.

In this way, the ship basically has combat effectiveness. Don't worry that when fighting with people at sea, it will overturn or shake its ship because of firing.

So Yu Xiaotian arranged a new task for the ship again, sending the ship's personnel to load about 20 tons of cargo, almost stuffed the whole cabin, and went to sea for Chicken Cage Bay.

Through such a voyage, the stability and safety of the ship is tested in wide and harsh waters after being fully loaded.

In order to ensure the safety of the ship and its personnel, Yu Xiaotian arranged two other boats to serve as escort ships to accompany it to Chickenlong wan.

Unexpectedly, on the fifth day, the Flying Fish ran back to Nanri Island first. The temporary captain who took the boat out told Yu Xiaotian, "The big master, the small boat came back first!"

Yu Xiaotian asked him, "Why did you come back by yourself?" What about the other two?

"Age of the great head! Those two boats are too slow! When we went, our Flying Fish was full of goods, and they couldn't catch up with us. As we walked, we had to wait for them. Later, we finally went to Chicken Cage Bay and saw them.

This ship is easy to unload. After unloading in less than a day, we set sail and returned according to the order of the great head!

The two rushes were really too slow, and the Flying Fish didn't load much goods, so I wanted to try how long it would take for the ship to come back as soon as possible, so I discussed with the brothers on the other two ships and brought the boat back by myself first!

If my subordinates are right, I guess they will be halfway through at most, and they won't be back until tomorrow night!" The captain replied proudly.

Yu Xiaotian was very happy to hear this and then asked, "So how long did it take you to start from Chicken Cage Bay and come back here?"

The captain immediately replied, "After the little one anchored from Jilong Bay, it took a day and a night and more than two hours to come back! Just run back!"

Yu Xiaotian calculated in his mind that through his two trips to Jilong Bay, the straight distance from Nanri Island to Jilong Bay is about 300 kilometers or even further away. In addition, if you have to take a certain detour, it must be more than 300 kilometers down. An hour a day and a night is 28 to 29 hours, so It can be concluded that the average speed of this new ship on the road should be more than 14 or 15 kilometers per hour. If converted into nautical miles, the average speed of this ship will reach about seven or eight knots per hour.

Such an average speed is already very fast in this era, and even the Galen ship currently used by Westerners may not be able to run out of such an average speed.

And according to his several trials experience, the maximum speed of the ship can basically reach about ten knots, or even exceed the speed of ten knots, which also shows that the speed of the ship is quite fast.

Although this is nothing compared with the speed of some modern warships that often run out of more than 30 knots or even 40 knots, the speed of some cargo ships commonly seen in later generations at sea is also about 1234 knots to 156 knots, and fast freighters are about 20 knots, but they all rely on them. The powerful power carried by himself has been hit. Nowadays, relying only on the current sail power, the ship can only run out of such a speed. Yu Xiaotian thinks that it is enough to be proud for the time being.

Of course, among the sail warships, there are also ship types that can run faster than the current sloop, such as a space shear ship, but so far, it is not yet time for him to build a spaceship, and his technical reserve is too weak. He can only build this structure step by step first, with a relatively small displacement. It is not too late to start with sloops with relatively low technical difficulty, and then gradually let shipbuilders accumulate experience, and then consider building larger and faster sailboats.
