10:27 a.m., Qingdao Smuggling Crime Investigation Bureau Pier.

Two brand-new anti-smuggling boats are berthed on both sides of the anti-smuggling pier inside and outside the barge. The hulls are slender and streamlined from bow to stern. The water resistance is greatly reduced compared with typical deep V-shaped boats.

After six consecutive days of sea trials, it can be felt that the bottom of the boat will generate a large dynamic lift when sailing at medium and low speeds, and the resistance is basically similar to the round bilge boats equipped before by Qingdao counterparts.

Due to its long angled line, V-shaped cross section, small waterline entry angle, large lateral ramp angle at the rear bottom, and appropriate appendage designs such as long skeg and bilge keel, it has excellent seakeeping performance. very good.

The matching of the ship's engine propellers is also very good. During the design, the maximum still water speed at the design displacement was not pursued, but a large main engine power reserve was left on the premise of meeting the speed indicators proposed in the design brief. This ensures that when it is loaded with maximum displacement, the main engine can still be driven to the highest speed, while the boat speed only drops by about 0.5 knots.

The maneuverability is also remarkable, it is stable during high-speed rotation, the heel angle is small, and the radius of rotation is only 5.5 times the length of the boat.

More importantly, it has a beautiful appearance and clean lines!

The upper floor is built with an arc-shaped front wall and a truss-type four-legged mast. The front deck is equipped with a machine gun, and the rear deck is equipped with a motorboat and davit. The skylight of the auxiliary engine room is opened in the motorboat's davit. Allowing the rear deck to have a larger space for activities.

In short, the deck layout is neat, compact and well-proportioned.

The side silhouette of the entire boat is both beautiful and neat, and has the majesty of a warship.

The shipyard helped paint the names and hull numbers of the boats. The one equipped to Jiangcheng Customs was China Customs 823, and the one equipped to Binjiang Customs was China Customs 825.

Although it was not named China Customs 001, Han Yu still loved China Customs 825. As soon as he arrived at Qingdao, he moved his luggage to the boat and has been living on the boat these days.

He makes a boat his home, so the anti-smuggling team members such as Guo Weitao, Xiao Gong and Jiang Shengqi naturally also live on the boat. Deputy Commissioner Li of Jiangcheng Customs, who led a team to take over the two anti-smuggling boats, could only live alone on the shore and was very embarrassed.

That's right, it was the customs leader who led the team to receive the equipment. Both anti-smuggling boats were customs equipment!

Because of this, all maritime anti-smuggling officers, including Han Yu, are nominally affiliated with the Smuggling Crime Investigation Bureau, but in fact have the dual identities of customs officers and anti-smuggling police.

According to the original plan, the trial voyage would take half a month.

However, plans never change.

At around 9:30 this morning, Deputy Commissioner Li and Han Yu received orders from the General Administration of Customs, the Provincial Military Region and the East China Sea Fleet's East China Sea Base almost simultaneously.

The only difference is that the order from the General Administration is conveyed through Qingdao Customs.

Orders from the Provincial Military Region and the East China Sea Base are conveyed through the North Sea Fleet Qingdao Base Command.

As soon as Deputy Commissioner Li received the order, he immediately went to the shipyard to handle the handover procedures in advance, while Han Yu quickly convened a meeting with all the crews of the two anti-smuggling boats and the accompanying armed police officers and soldiers.

There were more than fifty people in total, and the anti-smuggling boat's command cabin couldn't fit in, so they had to borrow the conference room of their counterparts in Qingdao.

In the morning, two cars and two groups of people came in succession, each looking more solemn than the other.

Not only did Guo Weitao, Jiang Shengqi and others see that something big was going on, they could even sense the tense atmosphere. Just when they were secretly guessing what happened, Han Yu coughed dryly and said, "Comrades, our superiors have assigned us an urgent task. We will conduct the remaining trial subjects at sea."

"Secretary Han, are you saying we have to return early?"

"To be precise, we set sail ahead of schedule, and the first voyage is the first battle. This is the trust placed in us by our superiors, and it is the glory of our 823rd and 825th boats!"

"Secretary Han, what's the mission?" Captain Liu of the 823 boat couldn't help but ask.

"The superiors require strict confidentiality. The specific tasks to be performed will not be announced until after setting sail."

Han Yu took out his mobile phone and put it on the podium, looked around at the crowd and said: "Now, please turn in your mobile phone and pager. The unification of boat 823 will be handed over to Li Guan for safekeeping, and Li Guan will help everyone bring it back to Jiangcheng. The unification of boat 825 will be handed over to Zhang Xiaojun The platoon leader reported it, and platoon leader Zhang Xiaojun took him back to Binjiang."

It was normal to hand over mobile phones and pagers before performing tasks. Everyone had no objection and quickly took out their mobile phones or pagers, lined up and put them on the podium.

Zhang Xiaojun, the armed police platoon leader, had a big head and asked with a grimace: "Secretary Han, are you saying that if we don't participate in the operation, we should go back to Binjiang first?"

"Yes."

"Why, why didn't you take us with you at the critical moment? That's not what you said before you came!"

I brought them here before, mainly because I wanted to take advantage of the opportunity of trial voyages and return voyages to let them experience the work and life at sea.

In fact, half of this goal has been achieved. In the past few days of sea trials, the anti-smuggling boat swayed much more when sailing at sea than on the river.

Especially the day before yesterday, the weather was quite bad, the sea was windy and the waves were strong, and the anti-smuggling boat swayed from side to side at its peak, reaching more than 30 degrees. The two old marine policemen Guo Weitao and Xiao Gong, and the old navymen such as Jiang Shengqi and Wang Zhixin all vomited. They, the armed policemen, vomited. It got even worse. First he vomited out the food he had eaten, then vomited yellow water, and finally started to vomit blood!

They had just recovered today and were on an urgent mission. It would be a shame not to take them with them at this time. Unfortunately, some things cannot be softened.

Han Yu took a deep breath and said helplessly: "Platoon Commander Zhang, I can understand your mood, but the first thing I have to consider now is how to complete the tasks assigned by my superiors.

Considering that the upcoming voyage will take a long time and the endurance of the two boats is limited, bringing you along will directly affect whether we can successfully complete the tasks assigned by our superiors. "

"There are only twelve of us here. We can't fit in one boat. We can divide a few people into 823!"

"The endurance I'm talking about doesn't mean that the ship can't be crowded, but that once you get on the ship, you will have twelve more mouths. Our fresh water tank is only so big, and we must calculate all kinds of consumption."

"We...we can save water."

"Comrade Zhang Xiaojun, stop talking, this is an order, there is no need to bargain!"

Han Yu looked at the disappointment of the young men, thought about it and explained: "Even if you don't get on the boat, we still have to save water. In the next month, we won't even be able to have hot meals.

The tonnage of the anti-smuggling boat is not small on the river, but it is just a small boat on the sea. When a wave hits a pot of water, it will be gone. It is impossible to cook, so we may rely on dry food to satisfy our hunger. "

It takes a month to sail!

Guo Weitao, Jiang Shengqi and others reacted and secretly wondered what the mission was.

Han Yu didn't know what they were thinking, so he took out his notebook and looked at it, and then said: "Now to arrange the tasks before sailing, I have communicated with the shipyard, and they will bring people over before twelve o'clock at noon to install it." Roland C'. Lao Jiang, Lao Liu, you should be familiar with Roland C, please help me with the installation and debugging later."

"Roland C" is an electronic navigation system. In the past two decades, the navy and fishing vessels have relied on "Roland C" for navigation. However, "Roland C" has fallen behind and has been eliminated by Western countries long ago.

Jiang Shengqi found it incredible and couldn't help but said: "Secretary Han, our boat is equipped with the most advanced navigation equipment, including two color navigation radars, electronic charts, GPS global positioning system, and radio direction finder... "

"I know."

Han Yu put down his laptop and said solemnly: "If we carry out an anti-smuggling mission, these electronic devices, especially GPS navigation, can help us a lot, but what we are going to do next is not an anti-smuggling mission. GPS is very advanced, but the GPS satellite positioning system is from the United States. , we cannot rely on the U.S. satellite positioning system."

The next thing to be carried out is not an anti-smuggling mission...

Everyone was stunned and couldn't help but think of the increasingly tense situation in the Taiwan Strait during this period.

Han Yu looked around the crowd and gave an example: "On July 23, 1993, the Chinese cargo ship 'Yinhe' suddenly stopped and drifted while traveling in the Indian Ocean. It was not that the host machine failed, but that the GPS navigation had no signal and the crew could not tell the direction. , unable to continue sailing.

At first I thought it was a malfunction in the signaling equipment, but no matter how I repaired it, it didn't help. Later I found out that the United States deliberately stopped the navigation signal in the sea area where the "Yinhe" is located, because it suspected that China was sending weapons to Iran.

The lessons from the past are there, and we must learn from them. Not only can’t you rely on GPS navigation, but you can’t also rely on the ‘Roland C’ that will be installed soon. In short, it is dangerous to rely too much on a single form of ship positioning because we have to take into account possible electronic interference. "

Han Yu paused and then said: "So please take the time to study the charts and think about what you learned in the military academy and training some time ago. The magnetic compass and sextant have not withdrawn from the stage of history. We You must master the skills of not yawing or even getting lost in an environment of endless signal interference!”

The sextant is an essential instrument for navigation. It has the advantages of simplicity, reliability, good concealment, low price, and no coverage area restrictions. It still occupies a place in the navigation industry today.

Both naval academies and local maritime academies regard sextant as one of the compulsory subjects. Proficient use of sextant to determine orientation can be said to be one of the skills that professional navigation officers and soldiers and senior merchant ship crews must master.

Jiang Shengqi realized what mission he was going to perform next, and was secretly frightened. Han Yu said again: "Gong Jian, Wang Xiaolong, your mission is to seize the time to purchase all kinds of supplies needed for the voyage. You have to act quickly. It must be at 5 p.m. Finished before clicking.”

"Secretary Han, how many days will it take to prepare?"

"Don't ask me how many days it will take to prepare. I only have one request. The oil and water tanks must be filled, the refrigerator and freezer must be filled, and more dry food that is not easily spoiled must be prepared. Bottled water must also be prepared. As long as the boat can hold it, Come on, as much as you can fit."

"yes!"

"Wang Zhixin, Jiang Guochang, you are in charge of the guns and ammunition. Prepare five basic rounds of machine gun shells, ten automatic rifles and two anti-smuggling boats each, and two thousand rounds of bullets each."

Wang Zhixin was shocked. He stared at Han Yu and asked, "Secretary Han, we are also the gunners commander. How can we prepare for standing here?"

"When Li Guan comes back, you take a few people with Li Guan to the Qingdao Smuggling Criminal Investigation Bureau to move the shells. As for the rifles and rifle bullets, Lao Jiang, you can go to the Navy Qingdao Base with me to borrow them later."

"Can I borrow it?"

"It should be possible, it must be possible!"

PS: I have a headache, fever, and severe discomfort.

Tested for antibodies and it seems to be positive again.
