A good night's sleep.

When Chen Yuan woke up, it was past seven o'clock.

It's sunny today, which means it's a little hot. The sun passed seven o'clock, and it had already seen firepower.

Chen Yuan got up to take a shower, shaved off the stubble, and looked in the mirror with a stinky look.

Chen Xin was cooking breakfast, but there was no heat in the kitchen.

Millet has just been put in the pot, there is a bit of water, and it is a low heat, which is cooking porridge.

Chen Yuan stirred the millet in the pot with a shovel, returned to the living room and took out his mobile phone, and clicked on WeChat......

Last night, Yan Xiaoxi sent a text message to Chen Yuan after returning home, just two words: good night.

Chen Yuan also replied with two words: good night.

After a while, Chen Xin came back with some steamed buns and steamed dumplings.

"It's time to eat." Chen Xin went to the kitchen to take a look and turned off the fire.

"When will your delivery arrive?"

"It's past nine." Chen Xin said: "I'll teach us how to surf later." ”

"Okay." Chen Yuan agreed with a smile.

Two baskets of steamed buns, two baskets of steamed dumplings.

Chen Yuan has a large amount of rice, one and a half baskets of steamed dumplings, one and a half baskets of steamed dumplings, and two bowls of millet porridge.

After eating, Chen Yuan cleaned up the kitchen and mopped the floor of the living room.

I bought a sweeping robot at home, and it feels okay to use it. However, after a long time, the floor still needs to be mopped by hand......

After finishing these things, Chen Yuan went back to the house and slept again, waiting for Chen Xin to take the windsurfing board back, then changed into a jellyfish suit, and wore a pair of cropped pants on the lower body, and waited for Chen Xin to unpack and change clothes, and then went downstairs together.

The fabric of jellyfish suits and swimsuits is similar in that they are quick-drying, stretchy, smooth, and non-absorbent.

The difference is that there is too little fabric in the swimsuit.

Go out surfing, snorkeling, in the summer or in the tropics, the scorching sun shines all the time, and the water reflects the sun. If you wear a swimsuit and go snorkeling, you will be sunburned and even peeled off in any place except where you wear a swimsuit.

Jellyfish clothing covers the body more and protects against ultraviolet rays.

Come downstairs, underground garage. Yan Xiaoxi, He Huan, they were waiting next to the car.

They are also dressed in jellyfish suits, full suits.

Chen Yuan helped put their windsurfing boards on the car, and couldn't help but glance at Yan Xiaoxi.

Yan Xiaoxi has a pure and slightly immature face, but she has a perfect figure and wears a life jacket...... The life jackets are all propped up.

Yan Xiaoxi discovered Chen Yuan's peeping.

Chen Yuan also found out that Yan Xiaoxi found that he was peeking, and he couldn't help but be embarrassed: "Hurry up and get in the car, let's go." ”

"What time is the tide today?" Chen Xin asked.

"Noon time. You have to learn fast and get a taste of what it's like to surf. Chen Yuan opened the car door for Yan Xiaoxi and went to the driver's seat as if he was running away.

Waiting for them to sit down, Chen Yuan started the car.

Come to the seaside.

Zhou Sheng and Zhou Lan had already arrived, and they had both assembled their windsurfing boards.

"Let's go down first." Zhou Sheng said.

Chen Yuan waved his hand, took the windsurf board off the car, and instructed Chen Xin and them to install the windsurf board.

Their windsurfing board length is only 2.75 meters and the sail is 3.2 square meters.

The 3.2-square-meter sail is very light, estimated to be only about 4 catties.

The board is also not very heavy, and it can be picked up lightly......

After installing the windsurfing board, Chen Yuan said: "You first stand on it and try to feel it, and then install the tail fin." ”

Yan Xiaoxi stood on the board, controlled the sail with both hands, and looked at Chen Yuan: "Right?" ”

"Your feet." Chen Yuan said.

They have foot coverings on their windsurfing boards.

Chen Yuan explained to them the essentials of controlling windsurfing again, and when he saw that it was almost possible, he asked them to install the tail fins: "You put on the foot ropes." In the overboard...... Don't panic and grab the rope with your hands, be careful of cuts. ”

"Got it. The knowledge of the foot rope you told us before. Chen Xin said.

"Let me remind you again. Also, don't panic when you fall into the water, swim over and hold the board, and then climb up. ”

Chen Yuan's board was also installed, and he led them towards the sea.

It's high tide now, and it's estimated that the tide is three or four minutes away. The surge is small and best for beginners......

Chen Xin stood on the windsurfing board, cautious, for fear of falling. It took a while to erect the sail and try to control the direction of the sail...... The windsurf board ran down, but after a while, the body lost its balance and fell.

Zhou Sheng was guiding Zhou Lan not far away, and when he saw Chen Xin falling into the water, he turned the sail and came over: "Are you okay?" ”

"It's fine." Chen Xin climbed onto the board again: "Why are you so well controlled, you can go wherever you want." ”

"You have to explore this thing yourself, and when you become proficient, you can do it too." Zhou Sheng said.

Yan Xiaoxi also set up the sail and saw Chen Yuan: "Chen Yuan...... Why doesn't my windsurfing board move? ”

Chen Yuan's gaze was on Yan Xiaoxi most of the time: "You try to turn the sail." The sail will only move if it has the strength of the wind. ”

"Oooh oh...... It's moving. ”

"You slowly feel the force of the wind on the sail, and then you control the sail to turn......"

He Huan squatted on the board, staggering.

Chen Yuan came to her side: "Huanhuan, stand up." ”

He Huan threw Chen Yuan a roll of his eyes: "I feel that the board is shaking so much." ”

"Don't worry, you can't sink the board." Chen Yuan pointed to the sail: "One or both hands are fine, stand it up." ”

Yan Xiaoxi's balance is very good, he has already run a long way, and he is trying to adjust the sail: "Chen Yuan, come here......" Yan Xiaoxi shouted.

Yan Xiaoxi controlled the windsurf for the first time, she ran out for a long time, the sail ate the wind, she wanted to pull the sail to turn, but she ran faster and faster.

Chen Yuan opened his sails and chased after him.

Chen Yuan's sail surface is larger, with 7.4 square meters. The larger the force area of the sail surface, the more force it will have. However, to catch up with Yan Xiaoxi, Chen Yuan made a circle and appeared next to her.

"I can't turn a corner." Yan Xiaoxi saw Chen Yuan appear next to him and shouted.

"Your body is relaxed, and your arms are ......," Chen Yuan said.

"Have you taken it easy?"

"Take it easy."

"Do you feel the sail tugging on your arm now......

Yan Xiaoxi nodded vigorously.

"The more wind the sail eats, the more force is transferred to the arm. You try to loosen up a little bit now......"

"Oooh oh ......"

Yan Xiaoxi's clumsy movements, Chen Yuan, who watched it, wanted to laugh.

But her figure is too eye-catching. She was wearing a life jacket but no life pants...... The hip curve is beautiful.

Chen Yuan tried hard to control his gaze, not daring to look at her figure more: "You relax slowly, don't use too much strength." ”

Waiting for Yan Xiaoxi's windsurfing board to stop, Chen Yuan leaned over and explained to her how to control the windsurfing board's turn.

Chen Yuan doesn't particularly understand the theory of sails, so he knows how to control sails.

After being able to manipulate, I will understand a little.

The sail is small above and large below. After the wind comes, pass the sail...... The air flow of the upper stroke and the wind flow below will travel a certain air pressure difference, and the combined effect will increase the flow speed of the stroke.

Looking at the information before, this phenomenon seems to be called Yangli.

The sail can go against the wind, and the lifting force is only to push the sail laterally, but not to travel forward. In order for the board to move forward, it is necessary to resist the force of the wind in the direction, which relies on the stabilizer board and tail fin mounted on the bottom of the board. Strictly speaking, the resistance will partially cancel out the lateral pressure of the wind, but the residual lateral pressure and the forward force of the windsurf form a combined force to push the windsurf diagonally forward.

Different windsurfing boards, in one direction...... The windsurf board is different, the speed is not the same, and the angle formed between the sail and the windsurf board is also different.

Generally speaking, the wind is usually drawn from the mast and the wind flows out behind the sail. So, the more upwind the windsurfing goes, the faster it will go.

Yan Xiaoxi ran with the oblique wind just now, and directly took the wind from the sail, but his body was too stiff and he grabbed the sail too tightly.

It's very troublesome to talk about these things, Chen Yuan is self-taught, and he is not a professional coach. can only explain some of the most basic things to Yan Xiaoxi.

"I told you before, it's you who control the windsurf, not the windsurfer. To control a windsurfing board, you can't just use the strength of your hands, you have to borrow the center of gravity of your body...... Don't be afraid to fall on windsurfing, just fall a few times and master the essentials. You're wearing a life jacket, don't be afraid. ”

"How am I going back?"

"Control the sail and make the board turn. Take your time and don't rush...... Yes, a small angle against the wind...... Now make the angle a little bigger...... Good ......"

Suddenly, Yan Xiaoxi fell into the sea, and quickly climbed up in a panic, seeing that Chen Yuan was laughing, he puffed up his cheeks, glared at him, and set the sail up again.

"Be careful." Chen Yuan said.

Yan Xiaoxi grimaced at Chen Yuan, set up the sails, and set the angle...... The sails followed the wind and ran.

Chen Yuan stayed not far from her, Yan Xiaoxi now let go of her courage and tried to control the direction of the sail, learning quickly, but fell into the water several times.

In about half an hour, they returned to the sea, not far from the starting point.

Chen Xin and the others also basically mastered the control of windsurfing. It can only be said that it is basic, standing on it is still wobbly, and if you don't pay attention to it, you will fall into the water.

"Go to Sanshan Island." Chen Yuan said.

"Uh-huh......" Yan Xiaoxi nodded vigorously, controlling the windsurf board with a beautiful big turn.

"Brother, you can teach me too. Look at Xiaoxi, they are about to become masters. Chen Xin squeezed his eyebrows and said.

"I learned it myself, and it doesn't have much to do with him." Yan Xiaoxi's face is a little arrogant. She learns at a fast pace, comparable to some beginners who practice for days.

Chen Yuan smiled and came to Chen Xin's side: "How are you learning?" ”

Chen Xin shook his head: "I can't control the sails well." ”

He Huan next to him also said: "Me too." ”

"When standing on a windsurfing board, you should relax your hands and feet, and don't be afraid of falling. Just fall a few times and find a good windcut angle......"

Zhou Sheng also ran over: "Don't listen to your brother's nonsense. Controlling a windsurf board is a gradual process, and you can get used to it at first, and then you will be able to get it right. It's like riding a bike. ”

Yan Xiaoxi ran in front, and he was about to reach Sanshan Island.

Sanshan Island is an undeveloped desert island.

The island is not large, about 1 km away from Hailing, and there is a wild beach near the mainland, where people often have picnics.

After a while, Yan Xiaoxi left them far behind.

"Brother, go and watch Xiaoxi, she is running too fast." Chen Xin was worried about Yan Xiaoxi's safety and said.

"Let's go. I'll take care of ......," Zhou Sheng said.

Chen Yuan nodded and chased after him.

This mother-in-law is too bold.

I almost died from drowning before, but on the first day I played windsurfing, I dared to run so fast by myself.

Chen Yuan cut the wind and chased after him around a corner: "You run slower." ”

Yan Xiaoxi turned his head and said pitifully: "I...... I can't control the speed. ”

Chen Yuan covered his forehead with one hand: "If you control the angle of the wind cut, you can control the speed." ”

Lin Xiaomian tried to tighten the sail, but the windsurf suddenly turned towards Chen Yuan, and when she saw this, she pulled it back in a hurry...... One accidentally fell off the board.
