A tanker that I guess not is seen often in German; the Stoc Regina of Stoc Tankers, Stockholm, Sweden. She is of what we in Sweden call "Väner-Max" size, thus small enough to enter the locks into the Lake Vänern from Gothenburg and eastward.
She was recently sold to Sirius Rederi of Donsö, outside Gothenburg.
More pictures of the Stoc Regina and other Gothenburg related shippin on this linke:
