Donald Cameron MacKay's sketch gives an idea of a Fairmile motor launch's relatively small size.

The short-range, lightly armed Fairmile "B" filled a need for coastal escort vessels in the St. Lawrence and elsewhere. Its 34-metre-long, wooden-hull could be built by smaller companies across Canada, including boat builders in Ontario's Muskoka district who had previously specialized in pleasure and racing craft. The sailor at the wheel gives a sense of scale, while the Fairmile's forward 20mm cannon can be seen to the left of the sketch.
