Yeah...makes you wonder how the hell did Otto Kretschmer sneak into convoys.
Sometimes i think nazis did cooperate with England in secret. When my crew see a ship at night sometimes i like to slow down to 1 knot and go to 7.5 m. with decks awashed or completly stop. With this an escort can pass me from 2500 m. it's even too easy to blow him away like this and sometimes it's too hard to do it. Just experiment with noise factor until you get it right.
