A cargo ship has broken down and is drifting near the coast of Haida Gwaii, the Canadian Coast Guard said Tuesday.

The coast guard says it has dispatched a ship to assist the disabled cargo vessel, not carrying dangerous materials.

A spokesperson with the Victoria Joint Coast Guard said the vessel, a deep sea cargo ship from Alaska, broke down at about 10 a.m. PT, 50 nautical miles off the west coast of Haida Gwaii.

A full crew of 27 is on board, and the coast guard says it doesn't believe the vessel will strike land.

The rescue vessel is expected to arrive at about 4 a.m. PT on Wednesday, along with a tug boat that's en route.
