I remember the old "aces of the deep", which had some enterviews with some U-boat top aces, and one of them said in an enterview that the sonar operator would listen carefully to the torpedo going away, and that we could tell if the torp was running straight or if it was not moving away as it should - a sign that it might be circling. So in theory it is possible to know if you have a circler or not.
My impression was that you hear "torpedo in the water" as soon as it is expelled from the tube and is perceived to be running. Is it not so?
