Canada operated a fleet of 17-ton tugs, built during the Second World War which were also called the Ville class. The current vessels are named after those vessels. There is confusion that the current Ville-class design was based on the British Pup-class tugs. The original 17-ton version was based on that design, however the new Villes are an independent design.
The Ville class was designed as harbour tugs. They have a low-slung shape that is ideal for tight maneuvering and nudging exercises on larger ships. Their kort-nozzle allows for a greater bollard pull however it loses its pull at anything over 10 knots (19 km/h; 12 mph) and loses speed in turns. The Ville class are 19.5 m (64 ft 0 in) long with a beam of 4.72 m (15 ft 6 in) and a draught of 2.74 m (9 ft 0 in).
Members of the class built on the east coast were given one Caterpillar 3406 diesel that provides 365 horsepower (272 kW) and Ville-class tugs built on the west coast were supplied with one Caterpillar D343 rated at 365 hp (272 kW). This power is directed towards a steerable kort nozzle which gives the class a speed of 9 knots (17 km/h; 10 mph).
