maintain depth

[melin71]

Is this a bug in the game, only way for me to maintain depth like 150 m i need allmost to have full speed. else is just never stop to dive.

i think there is a diving bug in the game i read somewhere, maybe a mod will fix it.

not sure of all the details on it so to avoid it i dont dive i just use periscope depth only

It's fixed by the UHS:

thx for the fix

[SeaTurtle]

Same problem here, what a pain.

Do you know how to get just the fix without having to install the full mod ?

Thanks !

I would like to know this myself. Anyone knows what and where to edit?

As a total nab in moding, I would say .. the answer is in the .sim and .zon files in the submarine folder. I tried once to fix it using the goblin editor, but I failed. Maybe a comparison between the UHS and stock files can give you an answer...

the'improved pitch and roll' mod works for me

I tried taking a peak at those files in goblin but i get all sorts of errors opening them so i gave up trying.

This isn't a bug. The deeper you get, the higher pressure you reach. The u-boat is like an airplane in the air. Your dive scope keeps the u-boat level. If speed drops you will sink, naturally.

It's the same principle with airplanes. The higher you get in the air the less dense the air will be and the greater speed will be needed to maintain straight and level flight.

It's not a bug. It's a shame they "fixed" something that should not be fixed.

Consider the depth when you dive: (The "square" was a typo, it should be cubic)

This makes absolutely no sense..

Yes the Submarine is like an Airplane with the Diveplanes in the sense that they "drive" the Submarine to a lower depth. Just as an Aircrafts Ailerons, Rudder and Elevators help it achieve its altitude.

The difference between a Submarine and an Aircraft though is that the Aircraft needs to be constantly moving at a certain speed and angle of attack to keep flight.

The submarine needs lower speeds (obviously it cannot reach the same speeds as an aircraft but in perspective). And has the advantage of buoyancy. If a submarine is badly trimmed and has negative or positive trim then it will have to keep up a higher speed and make more use of its dive planes.. if it has neutral buoyancy then all it needs to do is maintain steerageway so that the helm does not lose control..

I have the same bug, and I have UHS installed but my issue is if I order 150M I actually only get down to 135M, is this correct?

They don't only drive it to a lower depth. when the dive plates is angled so that the u-boat is going to surface, it will keep "fighting" against pressure IF you have set the u-boat to a specific speed.

There comes a depth when the u-boat cannot handle anymore depth and needs speed to compensate for it. This is where you're mistaken.

It's not a submarine btw, it's a u-boat.

It doesnt need to constantly keep moving to keep flight. This is where you are mistaken. A piper cub can fly with zero velocity. It's called velocity, not speed btw. You seem to misunderstand the principle of flight.

When you angle the u-boat upwards, you decrease the surface of the u-boat and therefore lowers the water pressure from above by huge numbers.

The pressure is on all sides of the boat, pushing down, inwards, and UP. In fact the bottom of the boat is deeper and under more pressure, therefore the tendency is to rise, like a balloon. It must be trimmed in order to maintain depth. The reason a boat underwater tends to sink is that the boat leaks, which increases the internal weight of the boat, requiring constant retrimming.

A boat at 200 meters can rise or dive with the dive planes even if it is only travelling at two knots. If it stops it has no way of changing depth except with the pumps, which make a lot of noise. If the boat is moving it has control, though this may be compromised by damage allowing water in.

Bottom line: If your boat in the game can't be controlled at depth except with high speeds, and with no damage, it is indeed a bug.

Yes but it is the top pressure that is really relevant for maintaining depth. The reason it is pushing in all directions is the same principle as how quicksand works. Water molecules "roll".

You CAN control it, with the pumps. Also do not forget the difference between cold and hot water.
