Hi


1) To be absolutely sure that u-boat is fully submerged (no matter what sea state is!) take it down below 15 meters .

2) It is a bug. On really rough sea if you are surfaced it's impossible to hear anything by hydro except some noise.

3) About this sinking ships: another bug. If it was happend occasionaly then ok, but this amount of sinking ships causes by wheater is not normal.

4) I think this info. refer to the compass.
