Trouble holding depth

[NipplesTheCat]

I'm sure I've heard people talking about this before (maybe I was sh3) but my crew seems to have trouble holding a depth. It seems the deeper I go the orse it is. I think I'm sh3 gwx you had to speed up a bit at depth to keep from sinking but maybe I'm wrong. Well that's what's happening here. I find my boat dropping way down to 200m where I have to give it slow speed ahead (number 2) to keep it from sinking and to rise any. What gives?

TDW's Depth Keeping Fix allows you to hold depth down to 170m and is included with New UIs with TDC I believe (can probably find the standalone version if you're not using TDWs UI mod).

Below 170m though, even with the mod you can't keep depth. Not sure if this is a submarine 'realism' thing or just the game being picky. Anything over about half a knot is pretty much suicide when escaping DDs so speeding up to keep depth below 170 often isn't an option.

After reading one of our submarines I tend to fall in line with the game model. The idea of hovering or simply going along at 2knots at 170 meters like in SH3 is unrealisic. Going deeper than the engineers licensed 90 meters would have been scarey

Well that makes sense then. It does seem to be below about 170 or so as you said. As long as its not just me, im aware of it now so ill be careful. Thanks.

I tend to keep it between 150-160m. 170 is the buoyancy cutoff, but close-range depth charges cause water disruptions that force the boat a little lower in the water. Above 170, these disruptions are overcome with trim (unless there are too many close together) and the sub returns back to your set depth.

If you take a few DCs close to the boat and they push you below 170 you can be in trouble fairly fast (especially if you're running TC32 to speed up your escape)!
