CCGS Alexander Henry instance of icebreaker
CCGS Alexander Henry is a former Canadian Coast Guard light icebreaker and buoy tender that served on the Great Lakes from 1959 to 1984. In 1986, the vessel was handed over to  the Marine Museum of the Great Lakes in Kingston, Ontario for preservation as a museum ship. Previously, during the summer months the vessel was also operated as a bed and breakfast. In 2017, the ship was sold to the Lakehead Transportation Museum Society in Thunder Bay, Ontario and in June, was relocated to the Pool 6 site on the town's harbour front, where Alexander Henry continues as a museum ship.Design and description
Alexander Henry is a light icebreaker and buoy tender that was designed to serve on the Great Lakes. The vessel displaces 2,497 long tons (2,537 t) and is measured at 1,674 gross register tons (GRT). The ship is 64.0 metres (210 ft 0 in) long overall and 58.6 metres (192 ft 3 in) long between perpendiculars with a beam of 13.3 metres (43 ft 8 in) and a draught of 4.9 metres (16 ft 1 in). 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). This gives the ship a maximum speed of 13 knots (24 km/h; 15 mph). No helicopter facilities were added to the ship as they were considered unnecessary for freshwater operations.Operational history
The vessel was constructed by Port Arthur Shipbuilding Co. Ltd. at their yard in Port Arthur, Ontario and launched on 18 July 1958. The icebreaker entered service in July 1959 with the Department of Transport's Marine Service as CGS Alexander Henry using the prefix "Canadian Government Ship". Named after Alexander Henry the elder, an 18th-century British explorer and fur trader, she was transferred in 1962 to the newly created Canadian Coast Guard and given the new prefix Canadian Coast Guard Ship (CCGS).CCGS Alexander Henry served her entire coast guard career on the Great Lakes, stationed on Lake Superior. In 1976, the vessel was used for an experiment testing the icebreaking capability of a hover platform pushed in front of the ship. Attached to the ship's bow, the hover platform worked well in certain conditions, but required too much fuel and made excess noise. The hover platform also became an impediment to the ship should the platform breakdown. The planned deployment to cargo ships was never approved and though the experiment failed, self-propelled hovercraft are now utilised for icebreaking. Alexander Henry retired from service in 1985 after CCGS Samuel Risley entered service.
