The CCGS Sipu Muin is a powerful, heavy hovercraft that is used for icebreaking on hard-to-access areas along the St. Lawrence River where conventional icebreakers cannot navigate. The hovercraft is also equipped as a buoytender, and can be used in search and rescue, environmental pollution response, and navigational aid construction and maintenance operations.
The craft is used as a buoytender in the Quebec Region, meaning that she can be called upon to lay, service and recover buoys. The CCGS Sipu Muin is equipped with a crane capable of lifting up to 4 500 kg. Her versatility and 23 000 kg payload enable her to transport any combination of cargo and passengers through areas that are not easily accessible.
Vehicles can be loaded directly on deck by a bow ramp, making the CCGS Sipu Muin particularly useful in pollution clean-up operations, since the craft is also completely amphibious. In addition, she is regularly assigned to search and rescue operations and navigational aids construction and maintenance operations.
Although the CCGS Sipu Muin is used primarily between Montréal and Trois Rivières, she can be deployed rapidly to any area under Coast Guard jurisdiction, like other Coast Guard units. Her home port is Trois Rivières.
The vessel is homeported in Trois Rivières, Quebec.

Greenland's parliament has unanimously backed a phased ban on discharges from ships' exhaust gas cleaning systems, adding another layer of environmental restrictions for vessels operating in Arctic waters and potentially affecting cruise operators using scrubbers to meet international emissions standards.
Russia expects to begin regular year-round eastbound shipping along the Northern Sea Route in early 2027, as additional nuclear icebreaker capacity, newer ice-class LNG carriers and pressure to redirect energy exports toward Asia bring the long-delayed ambition closer to reality.
The number of commercial transit voyages through Russia’s Northern Sea Route (NSR) had already surpassed the full-year 2025 total by the end of September, putting Arctic shipping on course for another record season as cargo volumes rise and more vessels test the route between Asia and Europe.
