A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they can or should not move under their own power, such as in crowded harbour or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, some are icebreakers or salvage tugs. Early models were powered by steam engines, long ago superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours.
The Voith Schneider Propeller (VSP) is a specialized marine propulsion system (MPS) manufactured by the Voith Group based on a cyclorotor design. It is highly maneuverable, being able to change the direction of its thrust almost instantaneously. It is widely used on tugs and ferries.
Canadian Forces Base Esquimalt is Canada's Pacific Coast naval base and home port to Maritime Forces Pacific and Joint Task Force Pacific Headquarters. As of 2018, 4,411 military personnel and 2,762 civilians work at CFB Esquimalt.
A radio-controlled boat is a boat or ship model controlled remotely with radio control equipment.
The Royal Canadian Navy uses hull classification symbols to identify the types of its ships, which are similar to the United States Navy's hull classification symbol system. The Royal Navy and some European and Commonwealth navies use a somewhat analogous system of pennant numbers.
The Ville-class harbour tugboats are a class of tugboats employed by the Royal Canadian Navy.
The Glen-class tug is a class of naval tugboat operated by the Royal Canadian Navy. Constructed in Canada, the class entered service between 1975 and 1977. The five vessels that comprise the class are split between the two major naval bases of the Royal Canadian Navy. The Royal Canadian Navy operated a fleet of tugboats during the Second World War which were also named the Glen class. The vessels of the current Glen class are each named after one of the vessels of the earlier class.

A ducted propeller, also known as a Kort nozzle, is a marine propeller fitted with a non-rotating nozzle. It is used to improve the efficiency of the propeller and is especially used on heavily loaded propellers or propellers with limited diameter. It was developed first by Luigi Stipa (1931) and later by Ludwig Kort (1934). The Kort nozzle is a shrouded propeller assembly for marine propulsion. The cross-section of the shroud has the form of a foil, and the shroud can offer hydrodynamic advantages over bare propellers, under certain conditions.
DT Quokka (1801) was a medium harbour tug operated by the Royal Australian Navy (RAN) until 1998.
