Depth keeping below 180m

I think it's cavitation that's the problem, at least in terms of being heard at that depth. Active is of course a different kettle of fish, but based on my time with Dangerous Waters and the way propeller noise changes with depth, the lack of cavitation modelling in SH5 would mean you make the same amount of noise regardless of depth - so where in RL, you might be inaudible to passive sonar at 200m doing 2-3kts due to the extra water pressure, in the game you're making as much noise as those 2-3 kts would make if you were at periscope depth.

If that's the case, then the only solution would be to allow the sub to maintain depth at lower speed (below 2kts) at depths lower than 170m - it's the only way to account for the cavitation variance short of actively reducing how much noise the sub makes when it hits a certain depth (which to me sounds much more complicated).

Since I don't have SH3, could someone tell me if SH3 allows you to maintain depth with 1kt below 170 metres? If SH3 does, and SH4 does, then why not SH5?
