[Kapitän Cremer]

I'm as confused as you are....

Sometimes one torpedo seems to make all the work and sometimes they just eat up every thing you throw at them..C2 being the worst of them...

However I found that a torpedo set to 8 meters and magnetic pistol can take out all small merchants and coastal merchants in one eel.

As for tankers try shooting a fish at 2 meters depth, set for impact while aming for the fuel right in front of the smokestag.....that should set the whole ship on fire....
