A couple of veteran tugs are hard at work in Halifax these days despite their great age and hard use. Both are small boats used for dredging and marine construction, and are forever shoving and towing scows.
Oshawa is the older of the two, built in 1969 at Whitby, ON by first owners McNamara Construction. I have taken scores of pictures of this tug going back over the years, in fact back to 1983 when I saw it first.
Aside from a few label changes for ownership, the tug has changed very little from its days working first for McNamara, then Cartier (in the photo) and now McNally.
