First time NYGM, and sinking
 

I have in the past always used GWX. Today I installed NYGM. Everything is working fine and did a mission. Now what gets me wondering after diving travelling at silent running doing only 1 knt I keep on sinking more and more. I can only prevent this at half speed where of course the enemy discover me.
Is this normal?
I recollect that doing a full stop in NYGM you do sink. But in my case I am sinking fast.

how fast is fast?
I once did a bout 1 meter per 10 minutes

Hard to say, I start sinking already at a shallow depth, not after 100m where I think this is supposed to happen?!? Not sure about that, would have to read up on that.
I presume about 100m in a half hour.

The point of boats sinking in NYGM is the "anti-hummingbird" effect. In the stock game you can stop your engines and just float - something they could never do at any depth.

I made a change to the sinking depth where it took about an hour to get to 100m IIRC. This was an attempt to simulate buoyancy trimming

I'll see if I can find it.

Humming bird effect has its merits when you are not at silent running. Then the crew monitors the actual u-boat depth with the help of trim tanks.


undo the damage of the xxi pump in the file zones.cfg if you want a change in this mod:
