I never had the chance to test it below this depth, as I am still stalking ships on the Eastern Approaches, but maybe you'll take it as a starting point.

I've already adjusted the submerged displacements for all the subs to make them hold depth. I had to do a little more tweaking on the VIIA to make it hold depth though (length and width adjustments). Most subs were around 740-790 for submerged displacement
