We get a lot of large ships either docking in Quebec City or passing through the most narrow portion of the St. Lawrence.  In either case, tugboats are often required to shove them this way or that.  So, within the confines of Bassin Louise, our protected harbor there are always half a dozen tugboats awaiting assignment.  Just before I left for Ottawa (the reason this blog went silent for a few days) I did this sketch of one of the big ‘ocean’ tugs.  A segment of a huge grain elevator is depicted (I hope) in the background.
