"Smitties" 

With over 200 tugboats, Smit is one of the largest tugboat companies in the world and is probably best known for its 3 massive, deepsea salvage tugs
which range from 14,000 to 20,000 horsepower.  The Four Smit tugs depicted in "Smitties" are much smaller (approx 1/10 the horsepower) but hard workering
all the same.  This foreshortened image shows them moored in New Westminster, BC, at the end of a long Summer day ship docking on the Fraser River
