The German tugboat Karl in the early 1960s

The port of Hamburg tugboat Karl in action, probably in the early 1960s. My colorization of an image in the M/S Maritime Museum of Denmark archive. The museum does not give a date, but the ship in the background seems to indicate that the photo by an unknown photographer was taken in the early 1960s. The Hamburg shipyard Johannes Ölkers built the ship in the early 1960s for the

 P & A shipping company.
