Fin stabilizer, also known as bilge keel, is generally installed in the bilge on both sides of the ship. The profile is wing shape, also known as side rudder.

Because its outreach cannot exceed the frame line of the ship's section, and the area of the fin cannot expand indefinitely, it is often divided into retractable and non retractable, and non retractable can be divided into fore and aft fin and middle fin.

To put it bluntly, the basic principle of this device is to increase the offset effect of the two lifting forces by expanding the bottom width, so as to reduce rolling and maintain stability. The higher the speed, the better the effect.

In particular, the non retractable type is widely used in future generations because of its simple structure and low cost. Even small fishing boats are equipped.

It is for this reason that people like Lorraine who have no intersection with HNA in future generations can know it, and they can't tell whether it is the wisdom of the old generation or the flash of science and technology.

In short, Lorraine put forward the only constructive suggestion in the whole meeting, and it took less than five minutes for the three masters to eat thoroughly, which perfectly solved the problem of excessive rolling of the new ship in shelling.

After the successful conclusion of the scheme discussion, Lorraine almost saw that in three years, a legend would be born and shocked the whole world!

Near the end of the meeting, Karen suddenly asked, "Captain, have you ever thought about the name of the ship?"

"Name..." Lorraine only pondered for a moment. "In the belief of the Vikings, there are a group of female martial gods riding heavenly horses. They shuttle through the battlefield of the world in armor and sword. They don't regard any party as an enemy, but only choose the warriors who died in battle and lead them to valhara."

"They are the gods most loved by warriors. They are honored as valkiri, the female martial god who looks for heroes and patrols the battlefield."

"I think it's a tailor-made name for the ship. I like it."

"Valkiri...?"

Lorraine nodded heavily: "the privatized three masted galleon, valkiri. She is our flagship in the future, a great warship destined to become a legend!"

……

The world, now and in the future, no one can predict its development direction. Just like fate cannot be guessed, even a witch cursed by Tarot like Noah cannot get a truly accurate answer.

Lorraine's recent feelings on this point are particularly profound.

Before he came to Boston, he kept calculating cause and effect, gains and losses. He once regarded the kindness of American elites as the biggest dividend, and never thought he really needed to pay a price.

As a result, fate played a great joke on him.

On the night of disgrace, the Jackdaw came to an end in the most tragic way. It was blown up by life and fell on the berth of the wharf when it was not sailing.

Lorraine tried to find the truth, but she did her best to find out nothing. No matter who was behind the scenes or in front of the stage, she couldn't find the damn trace.

While the investigation reached an impasse, another road was unexpectedly unobstructed.

He soon found a suitable new ship. He not only found the ship, but also met the shipyard and flagship that best suited him.

Haite shipyard changed its ownership and valkiri finalized it. The shipyard prospered day by day with the injection of funds. The three vacant docks have been restarted one after another. For another month and a half at most, even the No. 1 shipyard, which has been stagnant for half a year, can resound with the roar of machines.

On November 6, 1779, on the 13th day of Lorraine's stay in Boston, that is, the fifth day after varkiri's final draft, Haite and Karen accompanied him to visit the reopened dock 3.

This is the best dock in Haite shipyard.

Because of the special feelings for the road signs, even in the most difficult time of the shipyard, several boatmans here volunteered to be on duty, and the condition of various equipment has been maintained well.

The so-called reopening is just to send in the people who will be used for shipbuilding, assign dormitories and clean up.

So, there's nothing to see here.

Standing in the empty dry dock, Lorraine stretched herself comfortably.

"Four days ago it was dock 2, yesterday it was dock 4, and today it's dock 3... Haite, I'm impressed by your energy and efficiency."

Haite nodded excitedly: "although the shipyard has encountered difficulties, God bless me. I have always maintained a good personal friendship with the foremen and shipbuilders of several docks. As soon as I heard that we got out of the difficulties, they immediately gave up their rich salary and came back, which is very important to re-establish the construction team."

Lorraine said curiously, "boatman? Did they bring boatman?"

"Boston is the most developed shipbuilding center in North and central North America. There are boatmans waiting to work everywhere in Houwan." Haite waved. "We have money, orders and designers. We can relax the requirements for short-term employment, and then leave the people we want according to their performance."

"Just like this, daily supervision is hard."

"No hard work! Compared with the pain of having nothing to do, mere hard work is not enough to fear!"

What Haite said caught Lorraine's heart.

Nothing to do

The investigation of the mob is now in the pain of having nothing to do.

Bell, acharin and pierce are in the Ming Dynasty, and Haina and Wang are in the dark. The back hand and front are ready, and only the enemy is missing.

Lorraine could understand that the reason why it was so difficult was that his opponent did not see him as a target.

Those people just want to destroy the arms handed over by the Continental Army to the saints, and the mob attack is only a means, while the destruction of the Jackdaw and the lives of more than 20 sailors are just some small gains in the process of pursuing their goals, and no one will pay attention to them, and Lorraine can't find out and press down his opponent according to the hostility focused on him.

But the more you know, the more humiliation you feel.

The only thing he could hope for now was the 1500 long guns that were nominally still in his hand and had actually been handed over to the saints.

"Bait... Should I spill it?"

Meanwhile, flower shop 77 Wesley street.

SIG bored with choosing flowers and turned a blind eye to Ryan doing the same thing around him.

"Today, kidariel invited revere to lunch and heard revere say that Jefferson's social life has come to an end."

"He facilitated the shipyard transaction between kenvi and Haite at a good price. Kenvi found the ship and picked up a shipyard for nothing. In a happy mood, he finally agreed to let go of the arms."

Ryan raised his eyebrows: "no claim?"

"After all, he's just a smuggler. His interests are paramount, and he can work the governor of Virginia to thread the needle for him. Even if he says it on his face, he can make a profit this time."

"Well, that's why I hate businessmen," Ryan spat. "When are they going to deliver?"

"The goods will be delivered officially tomorrow morning. Revere is afraid that kenvi will find out the huge debt of Haite shipyard and dare not delay too much on this matter."

"So you have to do it tonight?"

Seager pinched the flower stem and nodded.

"Are the channels ready for you?"

Ryan smiled uninhibited: "poor sander, he doesn't know that three of the four people he trusts most have become our people. Now we can gather at least 300 people to Mary Daya without him. He can't do anything."

"So kenvi?"

"Kenvi seems to be investigating kidariel. We dare not attack his people for fear of startling the snake. However, he sent the Qing people on board to investigate the Southern District. According to his skin color and language, the Qing people are approaching sander."

"Will you help him?"

"Compatriots, we have prepared enthusiastic compatriots for him and can guide him in the real direction at any time."

"It seems that revere still can't get his gun tomorrow. It's too poor."

Seager's eyes narrowed into crescent moon, but only smiled for a while, and the smile faded.

"One more thing, did Rodney find it?"

"Rodney..." Ryan hesitated for a moment. "He had disappeared suddenly before. He often found important information, and there was no one around to communicate..."

"But I've never been missing for ten days."

"We can't find him." Ryan's voice dropped. "Harry and I have reviewed it several times. No one in Boston should know our existence except the royal secret service, including kedalir."

"The royal secret service... The servants of the king, even God doesn't know what they're thinking! If..."

Seager spoke softly, his tone changing from light to slightly inaudible.

"Obviously, we are companions. We only feel busy alone. It's really not very good..."
