For my project “Pilots of the World” I visited the Port of Rotterdam, one of the biggest harbors in the world. 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 station at the Nord Sea to the Interforest Terminal at Prins Willem Alexanderhaven in Rotterdam. During berthing master and pilot keep an eye on it.
