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 pontoon. 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, we can feel 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 boat equipped before by our colleagues in Qingdao.

Due to its long angled line, V-shaped cross section, small waterline entry angle, large lateral ramp angle of the tail bottom, and appropriate appendage designs such as long skeg, bilge keel, etc., 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 ensured that it would

When the maximum displacement is loaded, the main engine can still be driven to the highest speed, and the boat speed only drops by about 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 times the length of the boat.

More importantly, it has 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, the rear deck is equipped with a motorboat and davit, and the skylight of the auxiliary engine room is opened in the motorboat 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 is China Customs 823, and the one equipped to Binjiang Customs is 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 have to live on the boat. Deputy Commissioner Li of Jiangcheng Customs, who led the team to take over the two anti-smuggling boats, can only live on the shore alone and is very frustrated.

Excuse me.

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 officers.

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 Headquarters.

As soon as Deputy Commissioner Li received the order, he immediately went to complete the handover procedures with the shipyard 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, but the anti-smuggling boat's command cabin couldn't fit inside, 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.

Guo Weitao, Jiang Shengqi and others not only saw that something big was going on, they could even feel 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, and 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 in advance, and the first voyage is the first battle. This is the trust of our superiors in us, 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 the voyage is set off."

Han Yu took out his mobile phone and put it on the podium, looked around the crowd and said:

"Now, please turn in your mobile phones and pagers. The unified handover of the 823 boat

It will be kept by Li Guan, and Li Guan will help everyone bring it back to Jiangcheng. The unification of the 825 boats will be reported to the platoon leader Zhang Xiaojun, who will bring it back to Binjiang."

It was normal to hand in cell phones and pagers before performing the task. No one had any objections. They quickly took out their cell phones or pagers and lined up to put them on the podium.

Armed police platoon leader Zhang Xiaojun 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 the peak of more than 30 degrees. The two old marine policemen Guo Weitao, Xiao Gong, Jiang Shengqi, Wang Zhixin and other old navy officers 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 just recovered today and are facing an urgent mission. It would be a bit unreasonable not to take them with them at this time. Unfortunately, some things cannot be done softly.

Han Yu took a deep breath and said helplessly:

"Platoon Leader 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 battery life 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 Danshui warehouse is 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. We won't even be able to have hot meals for the next month.

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, and there is no way 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, then said:

"Now to arrange the tasks before sailing, I have communicated with the shipyard. They will bring people over before 12 noon for additional installation.

"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 boats have relied on

"Roland C" navigation, but

"Roland C" is outdated 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 notebook 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 carry out next is not an anti-smuggling mission. GPS is very advanced, but the GPS satellite positioning system is American, and we cannot rely on the American 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 *** who was getting more and more nervous during this period.

Han Yu looked around at everyone and gave examples:

“On July 23, 1993, our country’s freighter

The "Yinhe" suddenly stopped and drifted while traveling in the Indian Ocean.

, it was not that the host machine failed, but that there was no signal in the GPS navigation, and the crew did not know the direction and could not 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 it was the United States that suspected China of sending weapons to Yin Lang and deliberately stopped it.

The navigation signal of the sea area where the "Yinhe" is located.

The lessons learned from the past are there, and we must learn from them. Not only can we not rely on GPS navigation, but we can also not rely on the soon-to-be-installed

"Roland C". 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 must master the situation in the endless signal interference environment.

A skill that won’t yaw or even get lost!”

The sextant is an essential instrument for navigation. It is simple, reliable, well concealed, low in price, and not subject to coverage area restrictions. It still occupies a place in the navigation industry today.

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

Jiang Shengqi realized what task he was going to perform next, and was secretly frightened when Han Yu said again:

"Gong Jian, Wang Xiaolong, your mission is to seize the time to purchase various supplies needed for the voyage. You must act quickly and must be completed before 5 pm."

"Secretary Han, how many days will it take to prepare?"
To be continued...
