This is something to think about. If the merchants in the game carried DC's this would spoil one of my game tactics. If I cannot get away after an attack I will try and get under one of the merchants in the convoy to get away from the destroyers. Sometimes I intentially try and cripple at least one merchant in an attack should I need him for this purpose. So, in this type of scenario the merchant is not been asked to hunt you, but to get you out from under him so the destroyers can take over. Hell, they wouldn't even need depth charge launchers - just roll them over the side
