What Zhao Xin visited was not the hull that had been completed, but the hull that had just started, and from here, it can be seen the strength of the Dinghai Naval Shipyard.

This is the latest design, and there have been some improvements from before, mainly on the hull, but also on various structures.

Although the Dinghai Navy is based on the appearance of the Spanish sailing ship and constructs the ocean-going sailing ship of the entire Dinghai Navy, the internal structure is different.

The water chamber, synthetic wood panels, screws, and a host of other improvements have greatly enhanced its performance, almost inevitably, to adjust the entire system.

The fundamental reason why the development of ships is slow, and even in later generations, not any country can have large-scale shipbuilding technology is that the ship is a whole, and a sub-project has made a breakthrough, and if it cannot be applied to the height of the whole, it will be abandoned.

Many classic ship types are difficult to move forward in a hundred or even hundreds of years, and every improvement needs a lesson of blood and tears.

This is under the unscientific research system, in the Dinghai Navy, perhaps in the technical field, in the basic knowledge, and in the peak period of sail warships, there is a certain difference, but in terms of scientificity, from the very beginning, Zhao Xin formulated extremely strict rules.

The new type of ship is not launched casually, and must be tested by the pond before being launched.

This is completely different from traditional shipbuilding, where almost all the key steps are in the hands of master craftsmen or designers, who are at most drawings or simple models.

However, from the very beginning, it is necessary to test the scale of the ship, for example, the type of ship, all kinds of planks, mechanics, the basis of fluid mechanics, some calculations according to the scale, which may not be particularly accurate, but can detect problems in advance, without human life.

This not only greatly secures, but also speeds up the research cycle of new products.

In the initial experimental boats, almost all of them were based on the data of Western sailing ships provided by Zhao Xin, but in practice, after accumulating experience, especially some key data, especially the use of Eastern modules, these will inevitably affect the ship.

Now, after minimizing these effects and integrating all the systems, the final hull is quite different from that of a Spanish sailboat.

First of all, it's more narrow.

On the sea, it is narrow and long, which means that it receives less resistance, and some unique techniques, such as bow modifications, stern modifications, have been developed in long-term pond experiments, and these techniques have been applied to this new ship.

12,000 materials, the improvement is not obvious, but the relationship between the entire hull and the length of the hull, plus the use of some new equipment, makes it easier for the bow to break through the seawater, and the resistance is saved by at least 7%

It doesn't sound very high, but for a boat that has been sailed, it may take 10 days, or even a month, 7% may save two days, not to mention the application of sails.

Under the premise that the materials of the Dinghai Navy have surpassed the era of European sailing ships, not only the steel keel completed in one piece is used, but even the mast or something is also steel, which greatly strengthens the toughness.

Under the premise that physics can support it, a higher mast can be used.

Traditional sailboats, if the mast is too high, it is easy to tilt, but this tilt, what kind of height to avoid, what kind of situation can be avoided, these things, there is no way to try, for those designers, may only tilt to say, so in many designs, relatively conservative.

However, for the Dinghai Navy, there is no problem in this regard, and the tilt is mainly the relationship between the role of force.

The extent to which a certain amount of energy wind will produce a tilt can be calculated.

Maybe this formula is not a complete, scientific formula, but as an aid, it is possible, through a series of arrival experiments, to reach a relatively high value, this value, more radical, than the previous conservative type, a lot larger.

For sailboats, the main power is still on the sail, no matter what kind of sail, the power of the sail has a lot to do with his force, in the same wind situation, the larger the force area, the greater the power obtained.

Similar to Western sailboats, the application of soft sails is the embodiment of the whole, as for later, the emergence of clippers, it is to give this to the extreme, the various fluid mechanics, as well as the area of the sail, to the extreme, under the premise of downwind, can even reach 18 knots, or even higher speed.

The adjustment of the type of hull of the ship has reached the pinnacle of what can be achieved in this era, depending on the area of the sail, the area of force, and the wind that may be subjected, it may not be able to withstand all strong winds, at least, in the most common state, it will not roll over, and will obtain the maximum wind force.

This is the benefit of technological leadership, and the application of canvas has also solved the problem of force, and it is expected that the resistance of the whole boat will be reduced by about 10%, and the area of the entire sail will be increased by 35%.

In the end, the overall efficiency is increased by 40% without compromise, that is, the average speed of sailing ships in the past can reach at least 11.2 knots at an average of 8 knots.

Of course, it is impossible for a large ship to lose its power, even if it is a new sailing ship of the 21st century, at most, as little as possible, but a conservative estimate of about 10 knots is already predictable.

For the boat, the biggest performance indicator is the speed, especially the sailboat, because it will not use other power, there is no energy consumption, the faster the speed, the higher the benefit, this is the most important indicator of the sailing ship, and now, Dinghai Shipyard has made this indicator reach the extreme.

On-site observation of the construction situation, a large number of lifting machinery, and the use of some unique machinery, for example, the original hoisting planks, must be carried up by workers, which is a great physical labor.

The wood used on the sailing ship is all dried and the mechanism is relatively fine, this kind of wood, the specific gravity may be lighter than water, but not much lighter, the most important thing is that it is large enough.

Sometimes, specialized laborers, doing this all day, will be tired enough.

The shipyard of the Dinghai Navy has been co-ordinated before the start of the day's work, and there is a complete technical standard for how many workers are used and what is the approximate progress of the project, under which the workers and shipwrights can work at a relatively low pace, but the overall efficiency is guaranteed.

The crane is a variety of manual tools, for example, the universal screwdriver, not only can save effort, in a specific structure, such as a corner, or a corner place, in ordinary people, even the hand is not easy to reach into the place, but can easily reach in, seemingly simple change, but greatly save time.

Zhao Xin was very satisfied with the progress of the shipyard in all aspects, stayed in the Dinghai shipyard for almost a day, walked almost 4 docks, asked about the progress of the construction, and the problems encountered, solved some problems on the spot, and then returned.

In Dingjun, Zhao Xin is the absolute leader, the king, many of his actions have been paid attention to by all sides, even if there is no so-called news and the like, some middle-level and even attentive personnel are understanding Zhao Xin's movements.

The canal is certainly of interest, especially to the people in charge of the steel and cement plants, who want the construction of the wharf to start as soon as possible, so that they can work in advance near the wharf to ensure that they can use it once it is completed.

Zhao Xin went to the dock, but the time spent at the dock was not very long, and more time was placed at the Dinghai Naval Shipyard, what does this mean?

When everyone was considering Zhao Xin's meaning, Zhao Xin went back after the inspection and called some designers of the canal together to study the setting of the wharf.

The construction of the port, in the Dinghai Navy, is a relatively common thing, in the two years since the establishment of the Dinghai Navy, the Dinghai Navy has completed the construction of four docks.

These are not the original small wharves in the sense of the Northern Song Dynasty, but more than the large wharves like Jiangning and Guangzhou.

The construction of a river port is not a problem, the key lies in how much Zhao Xin wants to build and how big it is.

This was a big problem, but soon, Zhao Xin told them the result.

Two ports, you can choose a place close to the cement plant and the steel plant, two enterprises, one controls the other, and the other enterprises can use the exclusive freight yard or the public freight yard to enter and make reasonable use. As for the scale, in principle, no more than 150 acres.

Zhao Xin set the basic tone, which is much easier for the designers, the right place, relatively close, and suitable for construction, for the designers of the canal, almost instantaneously come out.

It is a 15-kilometer-long canal, and it is not a natural river, and it is necessary to test the water temperature and geographical conditions, which themselves are dug by them, and it is clear what is suitable and what is not suitable on it.

Soon, the specific location was selected, one is located 1.2 kilometers from the steel plant, and the other is located at 2.7 kilometers from the cement plant, which are relatively close places.

However, in the setting, there are certain problems, because on the canal, there are a large number of docks, some docks have not yet been opened, but the planning has been made, there are not many real places, under the leadership of Zhao Xin and the help of planning, two wharves were finally determined, one is horizontal, along the canal is longer, and the other is longitudinal, and the canal is only less than 200 meters of contact.

Zhao Xin took a brief look at the design, basically, it met his requirements, one was more than 140 acres, and the other was only 120 acres, which was slightly smaller than planned, but it did not affect the surrounding docks.

The matter of setting up a wharf is the whole Dinghai Navy, and most of the factories are concerned, and the current factories of the Dinghai Navy are almost all export-oriented, export-oriented factories, which need to be transported and need wharves.

Even if it is for those factories opened up specifically for the navy, they also need raw materials, and the area of the navy itself is a big problem, not to mention that even if there are no resources, it is impossible to exploit them, which takes up too much land.

A river port, one can be directly connected to the nearby river port, which is good news for any factory, but in the end, it is different news.

2 wharves, one led by a steel mill and one led by a cement plant, which is different from what they expected before, although they did not have the luxury, each factory has an exclusive wharf, but at least, such a long canal, there must be a dozen wharves.

What is 2, or shared, what can these capacities solve?

Suddenly, the hearts of the people below fluctuated, and even some activities were also carried out to Zhao Xin's staff team.

Zhao Xin knew what he meant after hearing at least four or five side knocks, and he gathered at least 10 heads of large enterprises, including steel and cement plants, together for a small public meeting.

The main issue, of course, is the issue of the setting of the port, there are only two, this is the limit of the canal, maybe in the future, there will be a few more, but in the last five years, there are only two.

This made everyone very disappointed, in their opinion, such a long canal, according to a port 500 meters long, 15 kilometers of ports, at least 60 ports on both sides of the river, they are not very demanding, not to say 60, there should be at least 10.

It's a pity that Zhao Xin's will is not something they can change, originally, Zhao Xin has no obligation to explain to them, but after that, Zhao Xin still told them that the reason why there are only 2 ports is because the main development direction of the Dinghai Navy in the next period of time is ocean-going sailing ships.

These people are all concerned about Zhao Xin's actions, Zhao Xin went to the canal, to the Dinghai Shipyard, they all know, they thought they were going to the dock, but they went to the shipyard for so long, then everything should be the shipyard's problem, and they all learned about the Dinghai Naval Shipyard through their own channels.

The enterprises participating in the meeting, basically, are the largest in the Dinghai Navy, accounting for almost seventy or eighty percent of the Dinghai Navy industry and commercial output, and their volume is very large, each of which uses more than 10,000 workers, and the most are steel mills and cement factories, which occupy the top spot with 90,000 and 60,000 respectively.

The shipyard, in their opinion, does not have much scale, even the largest Dinghai shipyard now, it only has four or five thousand people, which is not a very large number, but after they paid attention, they found that the seemingly small shipyard has infinite vitality, they put aside the port affairs for the time being, began to pay attention to the shipyard, a battle for ships, began again.
