Thank you for answering and helping narrow down the problem

. Storm conditions are set at 15,1. What I'm trying to do is to stay at the flak gun even if a wave comes over the boat. In other words, what is the parameter to change the "
underwater" setting? After a depth of 8 meters I'm taken away from the flak guns. I suppose a follow-up question would be, if I change the "
underwater" setting, would that affect the settings of enemy sensors as well?
