In real, the "Bugsier 2" is an Azimuth Tractor Tug with enough power to tow the VERMAAS under all conditions, incl. the tidal influence of the river Elbe or offshore! "Bugsier 2" would tow the VERMAAS with an average speed of 7 knots, well not at once and not against the first tide of course! The propulsion units are Aquamaster Azimuth Thrusters, comparable to the Schottel-Rudder-Propeller type, but with a slightly different clutch management.
