My watch crew seem pretty nonchalant at being 15m underwater...

The game of course runs fine if you don't, but it feels more realistic to me when I do that in heavy weather.

I remember reading a long time ago (long enough I've no idea where to find the reference) that during heavy seas, on this one U-boat, the watch crew relief came up only to discover that the entire standing watch crew had been washed away.
