Hey D40 .. I dont allow my boat to level off at a determined depth .. I Know that Its more realistic when Iam commanding My boat .. If you look at stoniams tuturials . he is in a middle of a depth charge attcak at one piont he had to comand , Blow ballast .. Because the boat was diving to deep .. So I know that these mods are making thoise changes .. I know that if you use the SD3 editor , Yoy can change the pre-determined safe dive depth when diving and crash diving , My last escaped of a depth charge attack rendered my boat to get about 20% damage .. I was Obs to manuver around 5 destroyers while rying to escape the middle of a convoy , in which I sank three merchants .. I think the way things are set-up .. you have to manage that aspect of not diving to deep . Its the imersion factor and your competencyeof being kaulean !
