Possible to "stall" a sub?

[Puster Bill]

OK, a question for those with actual, for-real experience in submarines: Is it possible to 'stall' a submarine. In other words, at low speeds and high angles of attack, can the submarine lose dynamic lift in a fashion similar to an airplane?

Logic tells me this should be so, and I have noticed the behavior in SHIII, but does anyone have any actual experience with this?

I've noticed that while running at slow speeds in deep depths, if I try to surface without increasing speed, the planesmen will increase the angle of their planes in order to comply, but if I'm going slow enough, I'll actually slow down and start to sink, yet they were able to hold depth previously with more moderate diving plane angles.
