CCGS Mamilossa

The ACV Mamilossa (pronounced ma-mi-lo-ssa), word in the Abenaki language that means “it walks from the shore onto the water”, is a heavy and powerful amphibious air cushioned vehicle that will be used to clear ice jams from rivers and areas that are hard to reach with conventional icebreakers. It plays an essential role in preventing floods in eastern Canada.

Due to its versatility, the ACV Mamilossa is used as a buoytender, meaning that she can be called on to lay, service and recover buoys and support navigation aid construction and maintenance operations. In addition, she is regularly assigned to search and rescue operations.

This air cushioned vehicle is equipped with a removable crane capable of lifting up to 6,600 kg. Her versatility and 23,000 kg payload enable her to transport any combination of cargo and passengers. Vehicles can be loaded directly on deck via a bow ramp. This last caracteristic makes the Mamilossa particularly effective on environmental response.

The ACV Mamilossa is based in Trois-Rivières and like all other Canadian Coast Guard units, it can be deployed rapidly to any area in Quebec region.
