Trawling Basics

A lot of people have had trouble learning not only how to trawl but also what the displays mean on the interactive screen. This guide will help out by explaining the basics of trawling as well as what the Scanmare displays mean.I have provided some of the basics, but there are many ways to trawl so feel free to tweak things to best suit you. As the game gets updates I will do my best to keep up with any changes to trawling, If anyone has anything to add please feel free to do so in the comments.

Trawling Need To Knows

There are images for the Hermes and the Lunar Bow below.












These are the trawl doors, they are connected to the warp lines. The trawling doors are designed to let water flow around them, the doors spread the net open in the water.







These are the warp line levers, they control the length of the warp lines. When they are pushed away from you they are letting the lines out which increase the length. When they are pulled towards you they are bringing the warp lines in which decreases the length. The length can be seen on the Scanmare System Sensor named Length(LEN), Door. There will be more on this in the next section.






This is the switch to either start trawling by releasing the doors or to bring in the doors and then the net. The doors must be 20m out before you can use the warp line levers.In order to bring the net in the trawl door length must be below 25m. Again, you can see the length on the Scanmare System Sensor named Length(LEN),Door.






This is the lever to control the movement of the trawl doors by a small amount.
You need to unlock the Scanmare DoorSensor & Control upgrade from port to use this.















To start trawling you need to have four people set in the "set trawl" positions like this.


















To bring in the trawling net you need to have four people set in the "Haul Trawl" position like this.

Scanmare System Sensors

This is an overview of some of the Scanmare sytems sensors that are important. As I've said before, this is just the basics to get you started. As you start fishing more you will tweak the settings to best suit you.











This is the Scanmare System which comes up when you interact with the screen in front of the control deck seat at the back of the wheelhouse. The list in this picture can be accessed when you click on the + symbol on the top left of the screen. The sensors in that list have the name then the abreviation in parentheses then after the comma is what that sensor is for. Ex. Flow(FLW),Headrope- shows the flow of water in to the headrope.


You do not need to know what all of the screens do, but there are some important ones that I like to keep an eye on










1. In the top left of this picture is the forward sonar, headrope screen. This screen shows a sonar image from the net looking towards your vessel. You can see the port(left) and starboard(right) trawl doors along with a sonar image of your boat and schools of fish that are coming towards your boat and therfore towards the net. The schools of fish are marked on the screen with a horizontal and vertical line. The lines show the degrees the fish are from your vessel. Where the lines intersect there is a number, this is how many meters the fish are from your net, This number will decrease as the school of fish gets closer.

~Some have had issues with trying to get the schools of fish into position on the Forward Sonar, Headrope screen. First make sure that you are not zoomed in on the Scanmare screen when trying to move the vessel to get the schools of fish in the right position.This no longer applies as you can now move your vessel while zoomed into the Scanmare screen Next you need to remember that the sonars view is from the net not the boat, so when you move left or right it will take a little bit for the schools of fish to move in the right position on the sonar screen as it takes a lot to get the net to move.


2. In the top right of the screen is the Navigation (NAV), Ship screen. This screen shows you your heading, your location and your speed which is important as you dont want to go too fast (With the Lunar Bow you can go faster, around 6kn; With the Hermes you should keep it under 5kn).


3. On the bottom left is the Length (LEN), Door screen. Which shows you the length in meters that the trawl door is from the stern of your ship. There is one screen for the port and one for starboard, the port screen has a red mark on the top right and the starboard has a green mark. The trawl door length can be controlled directly by using the warp line levers.


4. The screen on the bottom in the middle is the Distance (DST), Door screen. This screen shows you the distance the trawl doors are from one another in meters. There are a few ways to increase and decrease the distance between the trawl doors. First, when you go faster the distance will decrease and when you go slower the distance will increase. Last is with the Scanmare DoorSensor & Control knob which will only very slightly influence the distance.


5. The screen second to the right on the bottom is the Flow (FLW), Headrope screen. This screen shows you the speed of the water going into the headrope in knots.


6.The last screen is one of the most important. This screen is on the bottom right and it is called the Height, Opening, Clearance (HOC), Headrope screen. This screen is an upgrage that you must purchase from port called the Scanmare Trawleye.
On this screen you will see an H, O, C and a fish symbol. These show you the Height of the trawl bag opening, the clearance to the ground and the most important is the rate of fish mass entering the net. Next to the fish symbol you will see a number from 0 to 9, 0 is no fish and 9 is lots of fish entering the trawl net.


-With the patch v1.0.2h the sensor called Catch,Codend should now be working. This screen will give you information on how full your trawl net is.








There is another screen you will want up, you can only get this screen on the displays in front of the captains chair Can now use as sensor called Spider

The screen you want up is the one that shows a pentagon and has the sensors called Trawl Speed, Symmetry, Distance and Depth on it. You want this screen up because it will show you when you're net is optimal for catching the most fish. When everything on the screen is where it should be the center will turn green. Control over some of the sensors on this screen can be difficult as you will need to tweak one to adjust another. i.e. You can control the distance by going faster or slower as well as decreasing or increasing the warp line length, this will also control the depth but both are not directly controlled by these means. The Symmetry is something many have had difficulty controlling,You can control the symmetry by letting one warp line out farther than the other. Because you don't have direct control over some of the sensors the color will usually fall to the red, however don't worry as you will still catch fish. I know this seems a bit confusing at first, or possibly at second or third, but don't worry too much about not getting it. Just mess around with the settings and you will get a better understanding on how to keep everything where it should be.

For the symmetry let the Warp Line out 30 meters more on the right side, this will help to get the pentagon shape to be green which will then help to fill your trawl net.

There is another scanmare screen that you might want to have up but is not necessary.

• The Depth (DP), Door and the Depth (DP) #2, Door. These screens show the depth of the doors in meters. You cannot control the depth directly but you can influence them with how far you let the warp lines out as well as your speed.

-There are a couple other ways to tell if your trawl bag is getting full.

When you start to have more drag from the net and you have to use more throttle to accelerate then your trawl bags are getting full. However it is unknown how full they are by using this method but it is still a good sign that it is ok to bring in the trawl net soon. Be aware that the wave size will also affect this, the bigger the waves the more you will have to accelerate to get any speed.

 You can bring up the sensor screen called Tension(TNS). This screen will show the amount of tension on the warp lines. As your bag fills up with fish the tension should rise indicating that it is ok to bring in the trawl net soon. Be aware that the tension will also increase with speed, with decreased speed the tension will subsequently decrease.

If watching and not reading is your thing then go to the Extras section for a video by JaxyBeard that describes what the Scanmare Systems do and how to use them.

Now to Trawling

With all of the other sections knowledge here is how I trawl as well as my setup.

First I put my employers in the proper positions










Then I release the trawl net









Once the doors are more than 25m out I make sure I have the right screens on the Scanmare









Finally Depending on what vessel im using will determine how far I let out my warp lines. For the Lunar Bow I let out the warp line to no less than 50m, and for the Hermes I let them out to over 150m.With the game being further along it seems you do need to let your warp lines out much farther than 150m, test it out a bit to see what works best for you, 250m to 300m works for me some of the time. I then bring my speed to around 3 knots and then just let the ship go while keeping an eye on the various screens. If I am not catching anything after a while I will let out my warp lines another 100m or so then bring them back in to where I had them before.(this seems to help, not sure why)






When fish are going into the net the sonar will look like this.The screen will be all red and yellow which shows that there is a mass of fish entering the net. This is also shown on the HOC screen, the fish symbol will be red with the number 9 next to it. Now you have a lot of fish entering the net.

Also if you have the catch,codend screen up then you will begin to see the boxes fill up when you have fish entering the net.







You can control the doors slightly with the Scanmare DoorSensor & Control knob. The keyboard controls for this are the arrow keys (up, down, left and right). It should help with the distance of the doors, However from my experience the control is minimal to none at all, it is very difficult to control the doors at all with this. I do hope this is fixed in a later patch.





You only need to trawl for a few minutes, 5 or 10 is fine, to catch enough fish. You do not need to trawl for hours, also dont let your trawl doors out all the way, as I said before, around 125m to 160m is fine. With the recent updates the trawl time has changed, I will usually have to trawl for 15 to 30 minutes to fill up trawl bag.
~For tips on how to find out if your trawl net is full without using the Catch,Codend sensor go to the end of the Scanmare System Sensors section~


Once you have been trawling for a little bit and want to finish you simply bring in the warp lines with the warp line levers towards you.









Then make sure you have your employees in the right place.










Once the lines length is under 25m you hit the switch to haul in the net.












after this is done you will see this screen.










Now just wait for the loading to finish and your done!

Hi. I've been meaning to give a update to this tread for a while. One of the reasons i believe people having a hard time with trawling, is that it kept changing back when the game was new. As far as I've found out as of my latest playthrough, The depth of the trawl doors has a big say if you will catch fish or not. On the Lunar Bow, the trawl doors need to be below 50 meters depth, so i like to have LEN (m) (both red and green) up on my screen as well as DP (m) and DP#2 (m) so i can keep track if my depth of the doors (DP (m)) is below 50 meters. As for the Hermes, i will come back to this once i start trawling with it, but i think its the same concept, just doors need to be below 150 meters. will confirm once i get there. As for now, i leave you with this new information, and wish you happy trawling. Good Luck Trawling, Bon Voyage!

Thanks for the update @niten57 and @Son of a Bit. Glad to know I wasn't the only one. Sorry to hear about your computer getting stolen Bit. Hope you got some kind of resolution from it insurance wise that is.

[Son of a Bit]

@ Cap_Spencer, I haven’t been able to play since my PC was stolen but back when I was able to I had the same issue. I believe it’s a bug but I haven’t been able to look into it enough to say for sure. I just hope it’s fixed before I’m able to play again.

[niten]

@ Cap_Spencer, I have the same thing. All yellow and red and I think alright but nothing. I can sometimes get 20%.

[Capt_Spencer]

Can anyone clue me in as to why my sonar "screen will be all red and yellow", but I am getting 0 fish into my net? Is this a bug? I have tried adjusting everything from line length, speed, depth, and I can never get more than 15% filled in my net, to say the least about emptying and repeating the process.

[niten]

OK, I don't know what I'm doing wrong but I put my people in position and I hit the switch to let the lines out. When they get to 130 I set the levers to "set" but they don't stop. I set the levers to bring in the warp lines but they just keep going out. I put my people to haul and set the levers to pull in the lines but they just keep going out until they get to around 400m then the start coming back in. The warp line levers don't seem to have any control over them at all.

[madman.1982]

3 times wire to depth = money in the bank lol

[Son of a Bit]

I went ahead and changed what works best for the length of the warp lines. I am not on this game as much I used to be so please feel free to let me know what length works best for you and I will be sure to add it and credit your info. Thanks again!

[Son of a Bit]

tabac - yes, I apologize for not updating it. The depth is more important now, for trawling on the bottom especially, you need to have your warp lines out farther. it used to be that you could keep them in a bit more.
