I am a primitive

They used pennies to control the direction of the sailboat, trying to make the sailboat go crosswind, tailwind, and against the wind.

Said to be walking against the wind, in fact, it is not really against the wind.

When sailing against the wind, it is necessary to make some inclinations so that the sails are slanted to receive the wind. Correspondingly, the sailboat needs to zigzag.

Moreover, except when the wind is particularly positive, most of the time, the ship's navigation will have some deviations, which requires people to use pennies to adjust a course from time to time to prevent it from yaw.

After half a day like this, I watched the more and more proficient people controlling the sailboat, and the sailboat sailing continuously under the control of several people.

Han Cheng gradually frowned.

The reason why he frowned was because she suddenly remembered something.

This thing is how to control the steering of the ship.

Now, people in the tribe use pennies, which looks very convenient and easy to use.

But Han Cheng still found the problem from inside.

The purpose of letting the people in the tribe make sailboats is ultimately to let the sailboats in the tribe sail on the great rivers and seas.

The water there is very deep, which can be described as bottomless.

At that time, it would be unrealistic to use pennies to control the course of the ship.

Because there is no such long penny at all.

And even if there is such a long penny, no one can ignore the buoyancy of such a grown thing in the water itself, insert it into the bottom of the water, and use it to control the course of the ship.

So after thinking about it in his heart for a while, Han Chengcheng issued a new order to the people on the sailboat.

He told them to stop using pennies to steer the boat and use oars instead.

On the big river and the sea, the penny can't reach the bottom, and the paddle, which is originally a wave on the water, can still be used.

After hearing Han Cheng's words, several people on the boat abandoned the pennies as they said, and began to use the oars placed on the sailboat to control the direction of the sailboat.

Compared with using a penny to control the direction of the boat, when the paddle is used to control it, it appears slow and stiff.

It is necessary to keep paddling the water with the oar on one side, so that the sailboat will turn slowly and the speed is not fast.

Moreover, a person standing on a boat and holding a penny in his hand can control the direction of the boat at will, but it is not possible to use a paddle.

Of course, the narrow one, where one person can hold two oars, and the oars are on both sides of the boat is an exception.

When the time comes, Han Cheng wants to make the sailboat bigger. It is obviously impossible for one person to master the sculls on a sailboat.

So these four people hold a paddle in each hand, two by two, located on both sides of the boat, and grasp the direction of the boat by paddling.

The two people on the other side began to paddle hard with the paddles they held in their hands, while the other two remained still.

Because of the wind direction, it is necessary to adjust the course of the ship more frequently, which is much more troublesome than using pennies.

It didn't take too long for these people to be sweated out of embarrassment...

Standing here, Han Cheng frowned slightly as he watched the sailboat sailing under the control of several people.

He still doesn't like the way the steering is being used now.

This approach seems too clumsy.

It takes a lot of manpower and material resources, and the steering effect is not very good.

Today, small sailboats are being experimented with. Even so, when there are large sailboats in the tribe, how many people should be deployed on both sides of the sailboat to control the direction of the sailboat?

And the place where it is now can be called calm.

If you come to the rough river and sea, or encounter some more urgent situations, it will be even more unsightly to use this method to control the steering of the ship.

Besides using pennies and paddles, what other way to control the steering of the boat?

Han Cheng frowned and fell into deep thought.

At noon, under Han Cheng's signal, several people on the boat began to steer the boat upstream, while Han Cheng, Lie and other people who were visiting on the shore walked back along the river bank.

Several sailboats in the water stopped by the pier.

In order to prevent the sailboat from running around, they not only tied it up with cables, but also lowered the sails under Han Cheng's signal.

In this way, it can effectively prevent the sailboat from running randomly under the blowing of the wind.

After finishing these things, several people got off the sailboat, their legs were a little weak, and they all felt exhausted.

After such a long time, they will be exhausted...

"Tell me, how do you feel about this sailboat after half a day, and what do you think is not working well and needs to be changed."

Under the shade of the trees by the river, Han Cheng washed his face and upper body with clear river water, sat down on a stone, and looked around, most of them had washed their faces with river water, or were washing their faces. Man, said so aloud.

After hearing what Han Cheng said, he thought about it for a while and opened his mouth first.

"I think the steering of the sailboat is not good, especially after you can't use pennies and can only use oars, it is very difficult."

After Lame said this, everyone immediately agreed with him.

Especially those four sailors who had been steering the sailboat for a whole morning nodded their heads like chickens pecking at rice.

They definitely empathize with what Lame said.

Because now their arms are lifted up a little bit, they can feel the fatigue that is passed on.

I feel uncomfortable even washing my face.

This is all controlled by the direction of the ship.

"The sail seems to be a bit weak, it's not very good against the wind..."

"Sometimes, it's not easy to find out where the wind is blowing from, and you can't adjust the sailboat quickly..."

After the lame first spoke, the rest of the people also spoke one after another, telling some of the problems they felt in this morning's experience.

Lame and some other carpenters here have recorded all the problems that everyone said, and what they need to do next is how to solve these problems.

After solving these problems, the sailboats in the tribe can be further improved, and the performance can be improved accordingly.

However, there are some things that they don't need to worry about, because Han Cheng, who has the memory of later generations, has already thought of a solution to the problem the first time he heard about it.

For example, it is difficult to find the wind direction.
