Way back in 1972 I made my first trip to Europe. The purpose was to visit pipe manufacturers; Sandvik in Sweden and Manesmann in Germany. In Germany, I stayed in Düsseldorf and the traffic on the river was fascinating. Almost all the vessels were small engines aft bulk carriers, family owned and/or operated. The personalized touches were interesting; lace curtains at the windows, flower boxes, bicycles, and sometimes a small car stowed on the deck. During a layover, I visited Heidelberg, and saw the captain of one of these boats run it aground. His wife emerged from the cabin waving her arms and yelling at him.
I thought at the time, what a great subject for a model.
I returned in the early 2000’s to find these small freight boats to be disappearing; overtaken by much larger vessels like you show above as well as some American style towboats.
