Chapter 192: Tooth extraction

If it is a little advanced, it can reach a range of 30 kilometers.
In the vast Pacific Ocean, such a detection distance is obviously useless.
In the vast ocean, the distance between east and west, north and south, is calculated in 10,000 kilometers. What's the use for you to explore the top of 30 kilometers.
However, if you want to increase the detection range of the sonar, you have to increase the power. That is very power hungry. The general ship boss is unwilling. The cost is too high.
In the past, everyone used the simplest single-beam sonar, but the effect was not very good.
Later, it developed to multi-beam sonar, and the effect was improved. But it is still not ideal.
Later, it developed into electronic scanning sonar.
Scanning sonar works well. Information feedback is relatively accurate. But the power consumption is also great.
The more beams emitted, the more information is returned.
The farther the beam travels, the more information can be explored.
All of this requires strong power support.
The radar of the MiG-25 fighter is turned on, and the power is so large that it can cook a rabbit two kilometers away.
The power of the sonar of fishing boats is not as powerful as that of radar. However, the consumption capacity of sea water is much stronger than that of air.
With the same power, the radar can explore 1,000 kilometers. The sonar may be less than 100 kilometers.
At present, the multi-beam and electronic scanning composite sonar installed by Thunderbolt and Thunderbolt have a exploring distance of about 50 kilometers. The electricity it continues to consume is already considerable. Fortunately, the power consumed by the sonar can be provided by the Rock 500, basically without any cost. Otherwise, sonar is absolutely impossible to turn on 24 hours.
What does it mean to say so much?
Just before the arrival of the typhoon, use sonar to catch a few large schools of fish and get away.
If it were an ordinary fishing boat, such a dangerous thing would definitely be impossible.
You must know that the speed of a typhoon is often faster than that of a fishing boat. Ordinary fishing boats must take shelter as soon as possible.
Like a fierce typhoon like Butterfly, its destructive power must be very strong. If it is caught by a typhoon, the fishing boat will definitely be over. Even a 7,000-ton warship like the Xinye Ship, if it is not necessary, will not go head-on with the typhoon. Even if it is carried over, it will definitely suffer a huge loss. The radars, masts, and communication antennas of warships are all relatively fragile.
Even the Nimitz-class super aircraft carrier of the American Emperor is very dangerous when it encounters a large hurricane. Often the loss is not small.
The Thunderbolt and Raiden both have speeds of 40 knots, which can definitely outperform the typhoon.
Moreover, with the powerful power of the Rock 500, even if it encounters an eighth wind, there is enough confidence to escape.
After all, less than 400 kilometers west of the Diaoyu Islands is the port of Fujian Province. When necessary, you can go there to avoid the typhoon, it's fine.
"Everyone said, do you not?"
"dry!"
"dry!"
"it is good!"
The Pili adjusted course. Drive at high speed southeast.
It needs to enter the fringe area of ​​the typhoon as soon as possible. Then go offline. Then start the net. Then tidy up the guys and stray quickly.
"Those guys..." Ge Ming praised, "I'm really not afraid of death!"
"It's that Wang Bu'an again!" Xu Ban shook his head.
Who do you say is the culprit?
Not Lei Zhenzi.
Not a thunderbolt.
Nor is it an old monster.
But the harmless Wang Bu'an.
It was he who gave the two fishing boats the ability to dare to challenge the typhoon. Relying on the advantage of speed, we are fighting against the typhoon.
With the broadcast of typhoon information, all fishing boats in the surrounding waters have already returned to harbor for shelter.
Only the Thunder and Thunder are still trying to extract their teeth here.
Xu Ban did not stop either.
He knew that the plan was feasible.
He, Captain Lin Chengji, and Deputy Captain Fan Qixiang have calculated that as long as the operation is good, it is relatively safe.
After all, the moving speed of a typhoon is definitely not up to 40 knots.
As long as you can beat the typhoon, you have a chance of winning.
Sure enough, the Thunder only drove less than two hundred kilometers, and sonar had discovered it.
Dense echoes. After judgment, it must be a big school of fish.
Judging from the radar information, their current location is almost at the edge of the typhoon.
Standing on the deck, Wang Bu'an clearly felt the gust of wind intensified. Sometimes, gusts even reached level 8 or higher. The stagnant water on the deck was blown all over.
It seems that he has such a weak body, if he moves on the deck, he must firmly grasp the railing.
Otherwise, the gust of wind may directly blow him into the sky.
As for whether it can be found after falling into the water, only God knows.
In order to avoid accidents, he obediently stayed in the engine room.
This is also his basic duty.
Ensure that the power system is stable and reliable at all times.
"Go!"
"Go!"
"Everyone is in place!"
"Master Wang, please go back and rest in the cabin, it is too dangerous here!"
Lei Zhenzi shouted loudly.
The Thunderbolt began to adjust its position.
Raiden also began to adjust its position.
Based on the sonar's judgment, they decided to intercept the fish.
Two-boat operation.
The next oversized fence.
The Perak serves as the main work vessel. Raiden serves as an auxiliary work vessel. Practice makes perfect in this way of working.
The motorboat pulled the other end of the fence to the top of the Raiden.
The cranes of the two ships began to go off the net.
The fence is very large.
It is conservatively estimated that after the sinking, the fishing area will be at least several hundred thousand square meters.
When the school of fish passes above, the crane will quickly pull up the thick rope around the seine.
As long as the speed is fast enough, part of the fish school will be sealed in the seine.
Of course, this is just theory.
There are still many details.
For example, the timing of starting the Internet is very particular. It was early, and the fish did not enter. It's late, the school of fish is over again.
For another example, how can we quickly clean up the fishes after we set up the net?
Schools of fish are fleeting, every minute is important.
The speed is fast, and the second net can be accessed.
If the speed is slow, then you can only watch the big fishes disappear into the depths of the ocean.
Fortunately, Wang Bu'an doesn't need to know this.
He just needs to know that there will be a bumper harvest soon.
His only task on board is to ensure that the power systems of the two fishing boats are not malfunctioning.
This is the most critical.
Don't forget, the typhoon is nearby.
If the power system fails at this time, they will definitely be finished. The new wild ships are too late to rescue.
This is also the reason why Wang Bu'an will be pulled aboard.
The power system is designed by you and produced by you, of course you have to endorse it.
How to endorse?
The best way is to board the boat in person.
If there is a problem with the power system, you have to die.
"stop!"
"stop!"
Soon after, the fence was put to the end.
The depth is actually less than 500 meters. But it is enough for most fish.
Purse seine fishing objects are mainly clustered middle and pelagic fish {such as large yellow croaker, small yellow croaker, mackerel, mackerel, sardine, etc.}. If you are lucky, there may be tuna.
However, the number of tuna in the Pacific Ocean seems to be relatively small. There doesn’t seem to be a lot of salmon. It's hard to catch.
In short, the Thunder and Thunder did not catch much tuna or salmon before.
Unless it is very lucky. Otherwise, there is no hope.
However, every fisherman hopes to be able to catch tuna.
why?
Tuna is valuable!
The landing price is more than 100 yuan per catty.
If it looks good and has no scars, or if it is a rare variety, the price is more expensive.
The problem is that tuna is really not easy to catch.
It is difficult for ordinary fishing boats to find them.
Even if it happens occasionally, it is difficult to react. When the reaction came over, the tuna school had run away.
The swimming speed of tuna is extremely fast, the instantaneous speed exceeds 160 kilometers per hour, and the stable speed can reach 60 kilometers per hour, which is faster than ordinary motorcycles. It is simply a sharp arrow in the water. Encountered by chance, but also disappeared with a swish.
"Didi!"
"Didi!"
The echo from the sonar is very dense.
Lei Zhenzi carefully judged the location of the fish school. Waiting for the time to start the network.
The people around are also secretly praying for good results.
It would be great if it was tuna.
If there is a net of tuna, it definitely makes a lot of money.
However, after calming down, everyone knew that it was impossible. If tuna is so easy to catch, will the price be so expensive?
At any time, things are precious. It's not bad to catch one or two. Enough gas money.
Well, that's not right, now the gas money is negligible.
"Wow!"
"Wow!"
Suddenly, a big fish jumped out of the water, splashing white waves.
Wang Buan looked very clearly in the engine room. Definitely a big fish. Silvery white. At least there are three to four hundred catties.
"tuna!"
"tuna!"
Several people screamed in unison.
But the sharp-eyed they also saw it. Moreover, they also recognized that it was tuna that jumped out of the water.
This is terrible.
Everyone seemed to have been beaten up with blood, blood was surging, and eyes flushed.
Tuna!
There are really tuna!
Moreover, it is still tuna weighing several hundred catties. The value is extraordinary!
This huge tuna usually only exists in the depths of the Pacific Ocean. Usually you can't see it at all. Unless there are external factors that can force them out.
For example, tropical cyclones.
They must have been brought out by Typhoon Butterflies.
"Get the net!"
"Get the net!"
Lei Zhenzi issued an order ~EbookFREE.me~ Everyone immediately pressed the electric switch to pull up the main ropes.
Pull the rope first to enclose the fish in the fishing net.
"Wow!"
"Wow!"
Suddenly, more big fish jumped out of the water.
At this time, everyone can see clearly. It is indeed tuna. Moreover, it is a huge tuna.
"tuna!"
"tuna!"
"A lot of tuna! We made a lot of money! We made it!"
"Work hard! Divide the accounts by the head!"
Third today. Continue to ask for a few recommendation votes. Thank you.
