Well, this might sound stupid, but first i check the depth of their keel, lets say its 3,2 meters. I then set a magnetic torp at 4 meters, and the i make sure they notice me (flank speed). the stupid brits then turn against my position at full speed. I plot a collision course towards them, and fire the magnetic torp at about 3500-3600 meters, so it can impact before they start zig-zagging. then i just watch the big boom in the scope.
