Very strange
I can sink a c2 or c3 cargo ship with two fishes, almost all my hits in not a critical parts of the ship and usually they going down affter one or two hours in more or less good weather in storm they sink even faster.

A want to tell you my secret - it takes me 2 month to learn the basics, and 6 month to play the game at 100% realism - sorry in real life i` am a cook not a sub commander. So what i` am trying to say is - never give up so quickly not only in the game but in real life too
