Trouble maintaining depth!

[rudeltaktik]

I see.

I thought by maintaining air in ballasts to keep "neutral bouyant" would be the same as a scuba diver using their BCD to do so. But it's more like a shark, needing to always move to keep bouyant or else he sinks.

Looks like "rigging for silent running" is an oxymoron.

Thank you for quick replies.

So in high seas, you're dead in all cases. That's not very fun... SH3 has a big lack of realism about pressured air in ballasts and depth maintain .... For example, if I'm at 200 meters and I order "blow ballasts", my pressured air is wasted until I'm on surface. Else, there is no simulation of ballasts : in reallity, if I order "blow ballasts", they must be empty in maybe 15 seconds, and then your submarine rides up very fast..... and your air pressure level doesn't run down continuously !

This is the next part of the hardcode to improve !! A ballast system !

So this problem maintaining "neutral bouancy" is only happening with the NYGM-Tonnage MOD ??
Or is it common happenstance with the others?

It's theoretically possible to trim the boat using the pumps, but it's rarely perfect, plus the simple fact that all ships leak, which is why all ships have bilge pumps. The first problem is that by time you realize the boat is sinking or rising slightly it's already too late, and the likelihood is that you'll overcompensate. The second problem is that the pumps make as much noise as the propellers, so you might as well save the compressed air and keep moving.

Not really. If you manually set your speed at two knots you should be quiet enough to avoid detection and fast enough for the planes to keep you stable.

Yes, but I believe there is an option to shut it off.

GWX used to make the boat rise if it was going too slow, but they took that out a very long time ago.

The problem is that the boote IS sinking at 2 kts. I must run at 1/2 speed (3-4 knots) or higher to maintain periscope depth. Otherwise it is sinking at the lower speeds.

I noticed it only with the type XXI, and it cost me my life ....
