humm i dont know if the crew are merely not drawn, or not simulated in this situation, ill test 2morro.
set Depth to 7 , your readout will say your at 10. but setting manually to 7 means it will work.
cool thing is the deck gun wont work. nor should it.
the AA wich is above water does however. if your heading into waves you may end up blind and damp. so depending on your heading expect to need a brolly.
as for the crew. i would have to set my depth to 7 whils in the vicinity of a ship. and right now its too late to try
so ill see next time.
