Call this a continuation of yesterday’s post, but this is a model bow set . . . . Given all the features that could be discussed, focus on these for oldest/newest, smallest/largest, and least/most horsepower.  Also, one of these does not fit with the others, although all are tugboats.

Doris Moran

Again, identify the oldest/newest, smallest/largest, and least/most horsepower.

James William  Here she appears to be towing a mooring into Erie Basin Brooklyn. 

Millie B and Louis C.  These two certainly do not fit in with this post, but  . . . I’m posting this photo anyhow.  Previously, Millie B has appeared here.  Louis C has appeared here. I hope you’re getting ready with your answers.

Just guesses.

Oldest is Rowan M, and newest is Philadelphia. 1981 and 2017.

Smallest considering both length and beam is James William, and longest is Doris Moran although Douglas J is the beamiest. Lengths are 77′ and 118′.  

Least horses is James William, and most is Douglas J.  They range from 2800 hp to 4800 hp.

Besides Millie B, the outlier is James William because she has a push-knee bow–rather than a model bow.  Also, she’s the only triple screw here.
