I'm on my 6th patrol now, in a type IXB boat, realism set at 90%.
Assigned to grid CG85, before I reached Orkney strait (?) I chased/tried to intercept a convoy. Unfortunatelly a couple of warships aware of my presence so I had to dive and run silent while they depth charged me. Lucky for me I got away safely

Saved the game and will continue tonight.
Anyway, while being depth charged I wondered if it is possible to determine the distance between the depth charge (when it exploded) and my boat. I mean, can we estimate the distance by timing how long it takes for the shock wave to reach (and rock) the boat after the explosion? Is it modeled in SHIII?
Can we also determine the position of the depth charge is by observing how the boat rocks/sway? My thnking is, if my boat rocks/sway to the right first, then to he left, it means the DCs position when it explodes is on my left, and vice versa.
Thanks,
