This method is a boat, Hong Tao wants to drive the Haibo to Lin'an, the capital of the Southern Song Dynasty, for a circle! Was a 30-meter-long, three-mast ship big in the Southern Song Dynasty? Not really, Hong Tao has seen a bigger sea ship, it has 5 masts! Looking at that volume, the displacement must be at least 500 tons. However, Hong Tao has never seen a sailing ship like Haibo, let alone a ship with so many sails and such a high mast like Haibo. If it is really higher than the mast, the Haibo can definitely rank first, and the other ships of the Southern Song Dynasty are hard sails, and they can't make the sails too high, so they make up for it by increasing the number of masts.

In addition, the nautical charts from Hong Kong to the north have not yet been surveyed, and Hong Tao also wants to take this opportunity to take Wanwan Island, the Ryukyu Islands, the Japanese Islands, the Korean Peninsula, the Liaodong Peninsula, the Shandong Peninsula, and the southeast coast of China all around, even if the nautical charts of Asia are basically completed. Especially in the coastal areas of the Yellow Sea and the Bohai Sea, Hong Tao should pay special attention to it, which is occupied by the Mongols, and he may go to war with the Mongols.

After the rainy season in Jinhe Bay, just entering October, the Haibo with 60 crew members, facing the cool north wind, headed for Wanwan Island. At this time, it was the season of the monsoon to go down to the South Seas, and the Haibo also encountered two large Arab schooner fleets, presumably Arabs who set off from Quanzhou or Guangzhou and returned to their homeland with goods. Karl was familiar with their ships, as he had been a slave for a few months, and from time to time he would give Hong Tao instructions on which one was more like an Arab warship and how many slaves there were in it.

Hong Tao was not interested in these schooners, their tonnage rarely exceeded 100 tons, their hulls were slender and pointed, and they generally had two decks, and the lower layer was the oaring slaves. If the wind is too strong for the sails to propel the boat, the slaves have to stretch out their long oars and start rowing day and night. This kind of longitudinal spinnaker is very useful for small boats in relatively weak sea conditions, but like the Chinese hard sail, it is not suitable for large ocean-going ships in high sea conditions, and the propulsion is insufficient.

"It's a pity, I still want to capture a few Arab slaves!" Watching the five or six schooners get farther and farther away from the Haibo, Hong Tao clicked his lips. Just now, he had been thinking about how to leave all these ships behind, but he couldn't come up with a suitable way for a long time. If the Haibo was equipped with artillery, he would have tried to see if he could annihilate such a small fleet, but unfortunately now it is a crossbow arrow, even if it is equipped with incendiary bombs, the power is too small, once these ships disperse and escape, they are all galleys, and it is really difficult to chase in a short time, because a few Arab slaves put the Haibo into the situation of a pirate ship, which is still a bit uneconomical. According to Luo Youde, these Arabs are quite powerful in Guangzhou or Quanzhou, because they are rich, so rich! If you really want to make trouble, don't think about going to the Southern Song Dynasty port comfortably in the future.

"The Arab woman is very nice, my cousin loves it!" As soon as Karl heard that Hong Tao was interested in fighting against the Arabs, he immediately became interested, as a European crusader knight, he wanted everyone to be an enemy of the Arabs.

"Oh? Then I'll have to talk to your cousin and see if he has any experience. By the way, you said that my current Latin went to your side, can others understand it? "As soon as Hong Tao heard the woman, he also came to the spiritual head, this is called death and not changing, although he has been safe since marrying Bo Zhu, but when he has the opportunity, he will still expose his true face.

"Adults speak Latin better than my Chinese, just with an accent. But that's okay, if you can bring a boatload of sweet candy, they'll forget about your accent and forget about it all in no time! Maybe you'll be popular in the court with your aristocratic accent from the wonderful Orient. Hong Tao discussed the matter of sugar with Carl, mainly to ask him how to sell the sugar if it was shipped to Europe. As soon as Carl heard that Hong Tao could also make sugar, he immediately regarded Hong Tao as an existence second only to the Pope, and was basically on an equal footing with his emperor's cousin. According to Karl, a shipload of sugar to Venice is equivalent to a shipload of gold......

"Hahaha...... Oriental aristocratic accent! I hope they can still think like this, sometimes it is not necessarily Santa Claus who comes with a boatload of sweet candy, maybe it is a devil. Hong Tao wanted to tell Carl that he was not going to Europe to send warmth and sweetness to the European people, but to harm Europe. But in the end, I held back, and it was difficult to accept belittling other people's motherland in front of me, and it was pointless to be happy.

Compared with the Predator and the Whaler, the Hypo is a third slower, one is a light cruiser, the other is a light cruiser, and the speed is naturally different depending on the type and function. Now let Hong Tao choose, he will still choose the Haibo as the ocean-going ship, because this ship has combat capability, and the dozens of sailors on board and those whaling crossbows and incendiary bombs give him the courage to fight with others, and he doesn't have to flee in a hurry like a big rat who sneaks around and bites others.

"Bang bang...... "The Hypo sailed against the wind for four days and four nights, and the lookout on the lookout on the top of the mainmast rang the bronze bell.......

"My lord, the continent has been discovered at 30 degrees on the port side." As midship-apprentices, they perform a lot of daily work on deck, Carl and Bojiao are responsible for checking their work, and Hong Tao rarely goes on deck. Now he had a real captain's quarters, the largest of the three windowed cabins in the stern, which contained not only a bed, but also a bookcase and a desk, and even a three-seater sofa.

"What latitude are we in?" When Bo Jiao came in to report, Hong Tao was lying on his desk and continued to draw his chart, without raising his head.

"At 21 degrees north latitude, it should be Wanwan Island you are talking about...... Uncle, may I ask a question? Bo Jiao closed the door and asked in a low voice.

"What's the problem?" Hong Tao put down the compass and whalebone pen in his hand and rolled his little eyes.

"How did you know there was an island? You...... Haven't you ever been to the Great Song Dynasty? "Bo Jiao is 15 years old this year, and his perennial sea life and plenty of protein have made him develop quickly, and he has a layer of black fluff on his mouth, and if he doesn't listen to his voice, he looks like a young man.

"In your uncle's country, there is a thing called a satellite, which flies high in the sky, and looks down with a very large telescope, and it can see clearly wherever there is an island, where there is land, and where there is the sea." Hong Tao felt that he couldn't make up this story anymore, the more things these Tan family children knew, the harder it was to fool, and he had to tell more nonsense to fool them, and this thing would have to be exposed sooner or later.

"Is there anyone on the satellite? Uncle, have you ever been there? Bo Jiao rolled his eyes and had a new idea.

"Hurry up and get out of here, next time you come in without knocking on the door, I'll let you be a sailor, and I'll tire you to death!" Hong Tao knew what Bo Jiao wanted to ask, he longed to fly again, this Nima couldn't satisfy him, even just curiosity couldn't satisfy him, he couldn't build him a glider to prove his arguments.

"Hey, yes, glider...... If I had a squadron of gliders, and when it came time for a naval battle, I threw incendiary bombs from the sky, who would be able to beat me in this Nima! It's kind of interesting...... "Watching Bo Jiao run out, Hong Tao began to fantasize again, just thinking about it can't be done, and he has to quickly record it on the whale skin paper, or forget it in a few days, for all serious things, his memory is very short.

"But how is this glider going to take off? It can't fly without a high enough height......" Halfway through the drawing, Hong Tao put down the pen again, and pondered the take-off problem of the glider with his cheeks, and how to use the memory in his mind to find a weapon beyond the times has become his daily work. He is a person who likes to steal and play tricks, but if there is a way to use a slingshot to secretly hit others, he will never rush up and fight with others, this is his ethics.

The Navy hasn't played neatly yet, and it's starting to think about the Air Force again. Unfortunately, neither gliders, paragliders, nor hot air balloons are enough to replace warships, because they all lack a key thing, which is power. Without motivation, you can't control the direction by the wind alone, and you can't take the initiative to attack. Power is a thing, Hong Tao has been in the car in his last life, he has played with sailboats and airplanes in his last life, whether it is a car engine or a marine or propeller engine, and it can be easily repaired and maintained. If you give him a set of modern machining equipment, he will definitely be able to drum it out, the performance may not be very good, but it will definitely work, and now there is a mixture of oil as fuel, theoretically speaking, it is possible.

But theoretically speaking, this sentence is too harmful, and there is a big gap between theory and practice. Hong Tao stayed in the captain's room for four or five days to study, it was really a waste of sleep and food, his eyes were swollen, he drew dozens of whale skin paper, and there was still no progress, an engine suitable for the current manufacturing capacity has not been built, there is nothing theoretically possible, there are too many things missing. Relying on Jinhewan's casting technology alone, even the cannon barrel can't be cast, and you still expect to be able to cast the cylinder? Even if the cylinder block is there, what should I do with the seal? What about parts processing? Can the cylinder be cast, and the crankshaft can also be cast? The piston is also cast? This ripped out the lathe and machining again.
