Yes they tend to do that, unfortunately, you can get them to do this in deep water too by staying very shallow and dodging at the absolute last moment.
It's just one of those AI problems... I try not to exploit it too much, although I did during testing, repeatedly
, had to check those ports out
Realistically those ASW trawlers and other improvised warships weren't really capable of making enough speed to get away from their own DCs in such ocassions.
a quote(ish) from an American I saw on discovery channel on patrolling early 1942
"the yacht we were on had 2 depthcharges strapped to the stern, I'm glad we never saw an actual uboat, because if they hadn't blown us away we would have blown ourselves up..."
:hmm:
