Like jons sayd open each cfg file in game submarine folder
example
open data\Submarine folder
find lats say NSS_Uboat2A folder and open it
find file NSS_Uboat2A.cfg and open it with your notepad
find the line SurfaceDepth and change the number from 5 to 7 meters.
Now change the paramentrs in folders
NSS_Uboat2A and NSS_Uboat2D to 7
__________________________________________________ _
NSS_Uboat7b,NSS_Uboat7c,NSS_Uboat9b,NSS_Uboat9c,NS S_Uboat2A9d2 to 8
___________________________________________
and the final folder NSS_Uboat21 to 10
(i think its a XXI type of uboat :hmm: )
That should do the trick
now all you need to do is start a campaine and dive to 7-8 or 10 meters depend of what type you boat you have
