The Ville-class harbour tugboats are a class of tugboats employed by the Royal Canadian Navy.[2][3]
Canada operated a fleet of 17 ton tugs, built during the Second World War which were also called the Ville-class.[3] The current vessels are named after the those vessels.[4] 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.[3]
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.[3]
Ships[]
The five vessels are:
- CFAV Lawrenceville (YTL 590)
- CFAV Parksville (YTL 591)
- CFAV Listerville (YTL 592)
- CFAV Merrickville (YTL 593)
- CFAV Marysville (YTL 594)
Listerville, Merrickville and Maryville are based at CFB Halifax, on Canada's East Coast. Lawrenceville and Parksville are based at CFB Esquimalt.
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.[3][5][6] The larger tugs are also split between both coasts.
