They rarely I live near Kiel and basically all ubosts we got are in Eckernförde or Wilhelmshaven.
When they go into north so they usually drive around
Since the 212A got a new design with specific cells that uboat is made for long sneaky missions (max kn:20) but when they surfaced the max speed drop to about 7-10
Edit: obviously you meant in the second world war. im sorry then
