CCGS Alexander Henry is a former Canadian Coast Guard light icebreaker and buoy tender that served on the Great Lakes from 1959 to 1984.

Alexander Henry is a light icebreaker and buoy tender that was designed to serve on the Great Lakes.

The ship is powered by two Fairbanks-Morse 10-cylinder 2-cycle 37F16 diesel engines driving two shafts creating 3,550 brake horsepower (2,650 kW).

Attached to the ship's bow, the hover platform worked well in certain conditions, but required too much fuel and made excess noise.

The planned deployment to cargo ships was never approved and though the experiment failed, self-propelled hovercraft are now utilised for icebreaking.
