Zhen Qian also drew the appearance of modern high-speed sailboats, which were known for their speed and were very suitable for fast sailing on the sea, and were most suitable as motor boats.

This type of ship has a small freeboard and less superstructure, which not only improves the stability of the ship, but also gives full play to the role of the sail. The boat is almost close to the surface of the water to sail, the length-to-width ratio is generally greater than six to one, and its underwater shape is designed to minimize the resistance to improve the speed, but to maintain a certain lateral resistance profile, resulting in a particularly beautiful waterline, and even in the first waterline surface has a concave, long and sharp curve scissor-type head column is a situation suitable for racing, and can split the waves (cut the waves) at sea to reduce the wave resistance, so it is called flying shear.

Zheng He's treasure ship in the West is also good, there are many masts, there are also angle sails, the hull is huge, the length-width ratio is not high, the carrying capacity is very large, in addition to the lack of soft sails and sextants, other modern ship technology has appeared on the treasure ship, it is said that the largest treasure ship has a carrying capacity of 10,000 tons, far ahead of the world navigation technology before the fifteenth century.

"This type of ship is too narrow and long, how stable is it at sea?"

"The first thing we should consider when building a ship is the load capacity and speed, and stability cannot be the first condition!"

"What is a soft sail and what is the difference between a hard sail?"

“……”

Zhen Qian can't answer many people's questions, and he is not a shipbuilder, but he has seen some models of sailing ships in later generations, and as for the overly advanced truth, he can only say that he knows only half of it, and it is not very convincing.

"So be it!" Ke Ming is a little knowledgeable, he knows what the sea ship needs most, and he agrees with Zhen Qian's opinion, but none of these things have been experimented, so it's hard to say whether it's good or not, "I think you can make a model first, and then scale it up according to the scale, from small to large, what do you think?" ”

Zhen Qian naturally has no problem, he is also ready to integrate the sailing technology of later generations, although he knows that it is somewhat unrealistic, the requirements of warships and merchant ships are different, and now there are no artillery, and there is no meaning in real warships, so he prefers the design concept of arming merchant ships, and then builds real gunboats after the appearance of truly powerful guns in the future.

Ke Ming and several people designed the model of the sea ship, and the operability, stability and speed became the primary consideration of the new merchant ship, no matter what, even if it was to load less cargo, safety was the first priority.

The flywheel device is not suitable for appearing on merchant ships, although it can increase some sailing speed, but it occupies a small half of the space of the ship, and requires a lot of human resources, so this device can only appear on some warships in the future to improve the maneuverability of warships.

Zhen Jiu was a little dissatisfied, because the battleship he wanted was denied, at least temporarily, which was a big blow to Zhen Jiu who wanted to drive a large battleship!

"The technology of warships is higher than that of merchant ships, and we can't even build merchant ships now, isn't it a joke to build warships?"

Zhen Jiu bit a grass root in his mouth, sucked the juice in it, and said, "Isn't the flyship we are driving now very good?" Why build other warships? ”

"The power of gunpowder is clear!" Zhen Qian, Wang Tianxing, and Zhen Jiu walked barefoot on the beach, the night was high, the stars in the sky were dotted, the waves washed onto the beach, the high tide of the sea water had submerged the ankles of the three people, and the cold sea water gently caressed the surface of the feet, "Now the weapons on our ship are mainly fire oil bombs and thunderbolt bombs, this kind of weapon fired with a launcher is only two hundred steps, and it is difficult to hit the target if it exceeds this effective distance, which is of course because of the reason for the projectile landing point. Is it that horizontal launches have a higher hit rate? ”

Zhen Jiu knows this very well that the Eight Bull Crossbow at sea can accurately hit the target within a distance of 400 steps, but this weapon does not carry much fire oil and gunpowder, and it cannot be compared with the fire oil bombs and thunderbolt bombs thrown by the launcher, which is also the reason why Zhen Jiu should install the Eight Bull Crossbow on the ship.

"Let's put it this way, the real battleship will wait until there is a real ship-borne weapon, I call that weapon artillery, you ask Wang Tianxing, he should have seen the prototype of the cannon in the wolf's den?"

"Artillery!" Zhen Jiu looked back at Wang Tianxing and said, "What is artillery?" ”

Wang Tianxing grinned with a big "bang", which frightened Zhen Jiuyi and said: "Like thunder, an iron ball weighing more than a pound flies out of the copper pipe, and a waist-thick tree can be broken into two knots within two hundred steps, Zhen San's guy is already enchanted, and the copper pipe made is almost one person high, and it can be stuffed into four or five pounds of iron balls, and it can destroy the world within five or six hundred steps, but unfortunately the copper pipe is not strong, and it has exploded several times......." ”

"Two hundred steps can break a waist-thick tree!"

Zhen Jiu couldn't believe that Wang Tianxing's words were true, looked at Zhen Qian, and found that Zhen Qian nodded and did not deny it, and said with a bright light in his eyes: "Master! If there really is such a powerful weapon, when will it be used on ships? Zhen Jiu can't wait anymore! ”

"It should be soon!" Zhen Qian knew that small artillery had been successfully experimented, but large and medium-sized artillery was not made by enlarging small artillery, the key was the cavities and cracks in the cannon body, today's artillery is cast, if it is changed to forging, it needs to be drilled, but drilling is also very laborious, unless a lathe can be invented.

The power of today's artillery is still too small, if measured according to the standards of modern classic artillery, the wolf's den can now make some one-pound small cannons, that is, iron balls that fire at a pound in weight, such artillery is actually not as good as the original infantry guns.

The classic infantry cannon is also called a cavalry cannon, which can be pulled by a horse to quickly change positions, the weight of the shell is three pounds, about three catties or less, the firing range is within 400 meters, and it can also be set on the deck of the ship, such artillery is the real primary artillery.

Generally, the classic artillery on large warships is a six-pounder gun, firing a projectile of less than six catties, with a firing range of about 1,400 meters.

As for the larger twelve-pounder guns and twenty-four-pounder guns, they are generally defensive guns and city defense guns, with a longer range and greater power, because the weight of the cannon body is too heavy, it is not easy to transport over long distances, and it can only be fixed in one place for use.

Zhen Qian gave Zhen Jiu a general explanation of the principle of artillery, Zhen Jiu only remembered that artillery can attack targets thousands of meters away, and the whole person was completely immersed in incomparable excitement, the real god of war!
