You have to be within visual or hydrophone range of the ship when it sinks to get credit. I don't know if your hydrophones have to be working or not, but I would guess they do. You, personally, do not have to watch or hear the ship sink. It is enough that one of your crew sees or hears it. I don't know how radar figures into all this, if at all. I've never played that late into the war, and German radar sets didn't really have any longer detection ranges than hydrophones, anyway.
