Mystery tugs - Need help identifying

[Hawk75]

The Ecosse was there for sure. The bow is visible in this photo. I had cropped the photo to focus on a specific area for identification. There were a lot of vessels at this pier that day. It was a wonderful sight for those who love tug boats.

Looks like the other tug could be the Ecosse, one of the Nadro Fleet

What's up with the Hannah? Has she actually been sold to McKeil? I understood they were helping find a buyer for her but that she hadn't actually joined the fleet. Did she run at all this year?

Ok so the Carrol C1 and Bonnie B! and the one behind them is Carol C?

Carrol 1, alongside and the Bonnie B 111, rafted to the Carrol C. Correct William Lafferty

Seems to be Caroll C I (red) and Bonnie B III (blue).

Back on May 30, 2010, I was in Hamilton, Ontario. I spotted a number of tug boats (mostly from McKeil Marine). At this time I have identified 3 of the 5 vessels in the picture. Canadian Leader is the background, the front two tugs are Evans McKeil and James A. Hannah. I am unable to identify the two tugs at the rear. Unfortunately the names were hidden. Can anyone identify those 2 tugs?
