The almost-identical Vane tugs come in two sizes . . . externally distinguishable by the height of the upper wheelhouse.
Contrast the tower of Bohemia above with that of Sassafras below. Some I hear call the Bohemia etc. as the 4200 series and Sassafras the 3000 . .. as in horsepower.
Elk River and Oyster Creek . . . size?
Bohemia and Sassafras (?) again.
Anacostia . . . size?
Patapsco . . . size?
You were right if you grouped Patapsco and Anacostia with the 4200s, and the other two with the 3000 series.
I wonder about the communication going on here . . a line of kayaks heading up the river as Elk River is attempting to turn to port aka “to the left”.
