If I set depth to 6 meters, the uboat will surface, as if it simply surfaced normally.
Using the surface button set my uboat at 8 meter, which is too deep. With water sloshing over the floor of the conning tower. Ok, the waves where 2-3 meters high I think.
Manual depth of 7 meters seem to work ok when I tried it.
Fun detail. When the uboat is about to reach ca 8 meters, one crew at a time will disappear.They disappeared in 1-2-3, but not all at once.
