"Jiao, Carl, if you are the captain of the ship, what should you do at this time?" Seeing that Bojiao and Carl had come out of their fright, Hong Tao was also tired, but he still stood at the bow of the boat, enjoying the heavy hammer of the waves on his back, which was regarded as Singh's massage, and then began to teach the two of them the most basic knowledge of sailing. It's not enough to overcome fear, and there is more to this storm.

"Lowering the sail ......" Bojiao was finally not all scared silly, and still remembered how to sail in the wind.

"And aim the bow at the waves...... "Carl felt the steering wheel even more, and he loved the feeling of standing behind that big disc and spinning around.

"If you are sailors and helmsmen, this answer is perfect, but unfortunately you are the captain of the ship, and these tasks should not be done by the captain. At this time, the captain should hold the sextant and keep an eye on the hourglass, and make sure that the ship is on the right course, otherwise you will protect the sails and the hull of the ship, and it will be all in vain. It is most likely to deviate from course during a storm, and even if you can't see the sun, you should remember the approximate speed of the ship in this situation and mark it on the chart. In the unlikely event that it does deviate, this data is the basis for rediscovering the correct course. Hong Tao pointed to the sun behind the clouds, affirmed the two people's answers, and then told them how to be a good captain.

"Captain...... I, my chart was swept away by the waves......" Only then did Bo Jiao remember the whale skin he had put on the deck, he didn't need to look at it, and he could still be weird.

"Well, well, the people on your ship are basically dead, and you killed a boatload of people, so it's not too much for you to wipe the deck for a day, right? Carl, what about yours? Hong Tao let Bo Jiao talk about this waste, there are three charts, and the two of them have practice charts that are not considered scratch paper, even if they lose it, it doesn't matter. But they must be remembered, how to strengthen memory? It's punishment! Playing with the punishment of life, people have the strongest memory in a painful state.

"Mine is still there, it's always in my arms! Hey, hey...... "Carl is an old fritter, even if he is just as scared, he won't be like Bozhu who doesn't care about anything."

"Oh, can you show it to me?" Hong Tao asked with a wicked smile.

"Of course...... I can feel it...... Oh no...... No! Carl was quite proud at first, and deliberately turned his back to block the waves, and reached out to pull the whale skin roll out of his arms. But as soon as I opened it, I was dumbfounded, the dye on it had not dried yet, and after encountering water, it was all spent, and it became a pile of black color blocks.

"Hey, hey, hey...... It's fair, when the storm passes, you and Ah Jiao wipe the deck together, every place must be wiped clean, there is no food if there is a little water stain, hahahahaha...... I'll go get something to eat first. Hong Tao is very happy, as long as someone is worse than him, he can be happy, regardless of whether he is also unlucky.

The Explorer looks very fragile, in fact, it is quite sturdy, I have to say that Wen Laoer's craftsmanship is really good, except for a slight leakage in the bilge, this ship is basically intact to survive this not big storm, basically a cruising sailboat that can sail far away. But there is one place that Hong Tao is not very satisfied with, that is, the rudder, this thing is very important, once it is broken, it is not only difficult to repair, but also very fatal, such a large sailboat can not rely on the wind direction and center of gravity to adjust the direction like a sailboard.

The rudder is not broken, it is quite strong, but it is very heavy to operate in a big wind and waves, especially when it is crosswind. Hong Tao has already come up with a solution to this problem, and after he goes back, let Wen Lao Er change to a new rudder. More than a dozen fist-sized holes were drilled into the new rudder to reduce the resistance to rotation, but not to affect the action of the rudder. This technology has been applied to sailing ships for a long time, but most of the sailboats in later generations have hydraulic auxiliary power to assist in operation, so it is no longer a matter of trouble, so Hong Tao, who is proficient in modern sailing ships, did not think of this problem, which is not to blame Wen Laoer.

The storm was not too intense, but it lasted for a long time, almost 24 hours. At night, not even a single star was revealed, and the Explorer was really drifting on the sea, and the sextant was of no use. When the sun showed its face again, Hong Tao did not let Bo Jiao and Karl wipe the deck, but asked them to use a sextant to measure the angle of the sun five times in an hour, and after calculation, the course of the explorer was blown north by about 3 degrees.

"See, we deviated from the course for nearly 600 miles, and without the sextant and this chart, we would have sailed all the way to Qiongzhou. This is still offshore, and if we get to the ocean, these 600 miles will kill us. If you want to be the captain of a big ship, and if you want to return home as soon as possible, you both have to be proficient in this thing, and when you have mastered it completely, I will teach you how to calculate the correct course using the math I taught you. Okay, now it's time to wipe the deck, remember, you can't wipe it clean and you won't eat! "I don't know the principle, it's very difficult to rely on hard memorization to be familiar with the use of the sextant, but unfortunately Hong Tao has no time to train them to learn trigonometric functions before learning navigation, so they can only learn both ways and learn together.

"I'll use it first! The captain is my uncle! "This is the first time Bo Jiao and Carl have seen the power of the sextant, the loss of the chart has made the young man feel that he has no face to go back to see Grandpa, if he doesn't learn this sextant again, it will be a problem if Hong Tao takes him out next time. After enough pressure, people will be shameless, and they can use any tricks, such as nepotism.

"Carl, let him use it first, you take the helm, try to be the captain once, he is your navigator, the two of you try to cooperate once, see if you can take us home." I'm only responsible for helping you calculate the data, but regardless of the heading, the ship will be handed over to the two of you. "Hong Tao has no intimacy with Bo Jiao and Carl, since there is only one sextant, then he has to find some work for Carl.

"What if...... What if we both get it wrong? "Carl thinks more comprehensively, and the more he realizes the power of the sextant, the more timid he becomes, or rather cautious, which is a normal reaction, ignorance is fearless.

"Don't worry, even if you both live enough, I haven't lived enough! Remember, I am the master of the sea, as long as I am here, on the sea as on land, run boldly, let me see what you two have learned in the past few days. Hong Tao's words are too big, but it is in line with his identity at this time, for Carl and Bo Jiao, he is indeed very tall, it is not enough to give them knowledge, but also to give them confidence.

After arranging the work of Bo Jiao and Carl, Hong Tao returned to the cabin, lay down on the chart table made of huanghuali, and began to carefully sketch the chart with a new whale skin. There is a large proportion difference on the original chart, which was deliberately made by Hong Tao, who is a villain and not a gentleman. At this time, it is irresponsible to completely trust anyone, and no one can know the specific pattern of this chart except himself. Even if it is to be used by others in the future, it can only be a small area of it.

In addition to this chart, several inaccuracies on the sextant have to be modified, this thing Hong Tao can't do it himself, whether it's whale bones or hardwood, he can't play with his teeth too fine, and he has to go back to find a professional to help. First of all, based on the current sextant, we will make a few copper-silver alloy metal sextants, which are the only hard, corrosion-resistant, and relatively easy to process materials that Hong Tao can come up with. It will suffice to find a goldsmith with good craftsmanship, and they will have a way of making the fine gnaws of the teeth.

In addition, there are new ships and continued whaling, whale oil is sold very well, although the price of this kind of lamp oil with no strange smell and high burning brightness is not cheap, but for those wealthy scholars, officials, and merchants of the Great Song Dynasty, it is not a matter at all. Luo Youde's inventory is not much, and if there is a problem with the source of goods, the advertising work he engaged in in the early stage will be in vain. In order to build a bigger and better ocean-going ship, you have to fight for your life at sea! As soon as he thought of the feeling of being tired and having a sore back and legs, Hong Tao felt like he wanted to die. Once a hobby turns into a job, there's no fun at all.

The construction of the new ship is relatively easy, the ship type is still the Explorer, there is no need to renovate, and now that there is a family of Boss Wen, there should be no major difficulties in building it. It's just that the cost has to be multiplied several times, and a 20-foot ship needs more than 100 runs, and a 50-foot ship needs more than 600 runs. The main reason is that the demand for materials is too high, and a good 50-foot-long piece of wood is more than ten times more expensive than a 20-foot-long good wood, and it is not easy to find.

Hong Tao doesn't have to worry about money, as long as he can find a whale, it is equivalent to finding money. But when the sailboat is big, the sail will be big, and it is already a bit unreliable to use the heavy Li Bu, which is too heavy and too thick The canvas itself is a burden on the mast, and then the area is doubled, and the mast will have to be thicker and longer. This kind of wood is easy to find, but how to fix this heavy and long mast to the keel poses a serious challenge to the shipbuilding technology of this era. Therefore, how to find a canvas that is lighter than Lebanon cloth and can have good air tightness is the big problem that Hong Tao needs to face. This problem cannot be solved, the kind of galleon he imagined cannot meet the requirements of high speed and high seaworthiness, and there is no point in making a slow, top-heavy sailing ship.

"Alas, I've been around for a long time and come back, I still have to go whaling, I need bigger whales!" After pondering for a long time, Hong Tao didn't come up with a better solution.
