"I have a lot of boats, use my family's test, your grandfather will not come back until the sun sets, there are still two hours, don't wait for him!" But Huang Hai was an anxious man, he saw Hong Tao sew two broken sails together, and sewed a large string of bamboo braid rings on them, and also carried two crossbars up and down, very curious, pulled Hong Tao and let him use his own boat for experiments, and took the initiative to let his son drag the small wooden boat to the beach and run aground.

"This rope is a hoisting rope, pull the sail into a suitable position, and tie it tightly. This rope is a sail rope, through the hole of the partition, used to manipulate the direction of the sail, after finding the right direction, the rope is wrapped around this bamboo tube a few times, stuck on this hole and fixed. With the help of everyone, Hong Tao loaded the broken sail on the small wooden boat in the Yellow Sea, and then began to explain to everyone the main components of this sail and how to use them. Not only did Huang Hai and his cousins come to listen, but Hong Tao also called everyone on the beach, including the three children.

This kind of sail is very easy to operate, after being familiarized, only one person and one hand is enough, and the children in the later generations can operate the sail with one hand and the helm with one hand after simple training, Hong Tao believes that these Tan family members who take the sea as their home and take the boat as a mount will at least not be worse than those urban children in later generations.

It doesn't matter if you don't have a pulley, drill a hole in the stern partition, and reluctantly replace it after polishing it smooth, and then tie some knots on the hemp rope to prevent your hands from slipping, and use a bamboo tube more than a foot long as a cable locker. When you need to fix the sail line, wrap it around it a few times and get stuck in a small hole. In this case, you only need to sit on the stern gang, pull the sail line with one hand to control the direction of the sail, pull the sail line all tight, and the sail will be parallel to the hull, and then you can choose whether to eat the wind on the port side or the starboard side. As long as the sail line is loosened to different lengths according to the wind direction and then fixed, the sail will be full of wind. At this time, the upper and lower crossbars and cable-stayed rods will prop up the canvas, so that it cannot be deformed too much, and can only be blown into a bulge by the wind, driving the boat forward.

As for the problem of steering, Hong Tao also did it according to the model of the oP boat, that is, to fix a horizontal bamboo stick on the rudder handle, not too thick, and the thickness of the pickaxe handle. In this way, sitting on the stern of the boat, the left hand can push and pull the rudder handle through this bamboo stick, and the right hand can control the sail direction by manipulating the sail rope, and at the same time, the sail rope is also tied to the partition at the stern, and if you want to raise and lower the sail, you don't need the help of others, you can do it all by yourself.

This greatly liberates the labor force on the ship, no longer has to rotate to shake the wooden oar, just operating the sail and rudder, you can save most of the physical strength, only when there is no wind or need to hurry, you need the assistance of the wooden oar, a hand-cranked boat basically becomes a sailboat powered by sails. As for whether this transformation can be achieved or not, whether it can achieve Hong Tao's expected effect, Hong Tao is not clear, the test is good, you have to try!

"Raise the sails!" After the installation and explanation, Hong Tao is about to come to a maiden voyage. Everyone pushed the small wooden boat back into the sea, and Hong Tao sat at the stern, shouted at the top of the voice, and then pulled the sail line, and lifted the sail, which was full of patches and holes.

What is science? Science is the study that works everywhere as long as the method is right. Although small wooden boats are larger and heavier than oP boats, and although thick coarse cloth is not as light and dense as synthetic raw materials, the general principle is the same. The boat drifted a little on the surface of the sea for a few minutes, and when the waves found the right direction, the sail puffed up, and then the boat began to move, and went faster and faster, towards the middle of the sea.

"Azhu, your vision is good, tell your sister-in-law, why did you fall in love with him as soon as he came?" Everyone on the shore watched as the boat went farther and farther, and it was already faster than a rocking boat, and the boat seemed to be accelerating. The men were relieved that with this thing, they would be able to go down to the sea to touch more fish and crabs without rocking the oars and from the heavy manual labor. Of course, the women also know why men are happy, and Bozhu's second sister-in-law attributes all the credit to her sister-in-law.

"I'm going to weave a net......" Bo Zhu was asked by the second sister-in-law with a big red face, the state between her and Hong Tao is known to others, but she is still very embarrassed to say it directly in front of so many people.

"The nets are all finished, you might as well help your sweetheart braid more bamboo braids, maybe in a few days, you will have your own boat, just in time!" The second sister-in-law is also a broken mouth, and she is not afraid of being hated when she jokes about her sister-in-law, Bo Zhu is hiding, and she also chased after her to make up for it.

"Hahahahaha......" The men and women on the beach immediately burst into laughter, having their own boat means that two people have a family, this is the rule of the Tan family.

Hong Tao could no longer hear the laughter on the beach, he was engrossed in the shape of the sail, and then slowly increased the draft area of the sail. Because he didn't know much about the strength of this piece of spliced rags, and he didn't know the toughness of these bamboo strips, he didn't dare to rashly let the sails all eat the wind. Breaking the sail is a trivial matter, and if the mast is broken, it will be troublesome.

"Uncle Huang, will you try it too?" After a short period of experimentation, Hong Tao had adjusted the sail to two-thirds, and listening to the creaking sound of the bamboo bars and masts, he should be able to hold on, and the speed of the boat was about the same as the full speed of the hand-cranked oar. Seeing Huang Hai and Huang Lang sitting on the bow of the boat watching him operate, Hong Tao remembered that the boat belonged to someone else, so he was polite.

"Grandpa, I'll come first!" Fake politeness is the most shot to meet true sincerity, Huang Lang is obviously more sincere, as soon as Hong Tao's voice fell, he couldn't wait to jump up, even his grandfather was not humble, and he walked to the stern first.

"You just sit opposite, grab this rope with your left hand, and hold a bamboo stick in your right hand...... "Hong Tao didn't move at all, this set of equipment can be used on the port side and starboard side, and you can hand it to Huang Lang directly face to face." Originally, Hong Tao also wanted to teach Huang Lang the skills of operation, but unfortunately Huang Lang didn't give him this opportunity at all, and his left and right hands got used to it a little, and he began to operate it himself. For a family member who has been dealing with the sea all year round, how to find the wind and how to make the sail eat the wind is almost their instinct, and they only need to be familiar with this feeling, and they don't need to be taught by others at all.

"Grandpa! %¥¥#, effort-saving! %¥%¥#&......"Huang Lang's Chinese is not good, Hong Tao can only understand relatively short words, and he doesn't understand the last word.
