The Canadian Fairmile B was a motor launch built during the Second World War for the Royal Canadian Navy. They were adaptations of the British Fairmile B motor launch design incorporating slight modifications for Canadian climatic and operational conditions. Eighty-eight were built in Canada for service with the Coastal Forces of the Royal Canadian Navy in home waters, of which eight were supplied to the United States Navy.

They were known by their crews as "The Little Ships", "Little Fighting Ships", "Q-Boats", "MLs" or "Holy Rollers" (due to their violent pitching and tossing),[1]
