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 and loses speed in turns.
The five vessels are:
- CFAV Lawrenceville (YTL 590)
- CFAV Parksville (YTL 591)
- CFAV Listerville (YTL 592)
- CFAV Merrickville (YTL 593)
- CFAV Marysville (YTL 594)
Other auxiliary ships
The Royal Canadian Navy operates six other, larger tugboats, the 140 ton CFAV Tillicum, and five 250 ton Glen class tugs, and two 140 ton Fire class fireboats. The larger tugs are also split between both coasts.
