In the port of Rotterdam I was guided by Herman Broers, President of the Rotterdam Pilots. He had to work as a pilot once in a while to keep his licence as a pilot. We had several pilot trips. With the container vessel “Katharina B” (100 meters long and 18 meters wide) we sailed from the pilot cutter “Markab” (59 meters long and 11 meters wide) at the North Sea to the Interforest Terminal at Prins Willem Alexanderhaven in Rotterdam.
