Stealth Catch 22

It can be done in modern subs, with computer controlled ballast systems, but really it wouldn't be practical in a sub like a Type VII. You need some headway to make the planes effective to overcome any inaccuracies in trimming the boat.

It's also very noisy.

As for the sub rising or sinking, I prefer NYGM's balance model, called the 'Anti-Hummingbird Mod', not only because the boat sinks at low speeds or full stop, but because it's not just two meters; it keeps sinking until you do something about it.

This was a lot of fun in Aces Of The Deep. You would be at Silent Running for a while, and then your chief would suddenly say "Herr Kaleun, we cannot maintain depth unless we run the pumps!"

Sounds funny
Though it would be good if you could set the depth rudders manually to stop the boat from sinking further. This would work at least for the case of silent running while you still would have to be careful at full stop.

With NYGM to run under 100 rpm you need to go down to 1 knot, but the sinking rate is very slow, and when you make a small dash when safe takes you back to your depth.
