The Minch, 1928 Icebreaker |
 Icebreaker leading cargo ship. | A ship of special hull design and wide beam, with a relatively flat bottom, designed to force its way through ice. When the icebreaker charges into the ice at full speed, its sharply inclined bow, meeting the edge of the ice, slides onto it, and the weight of the vessel causes the ice to collapse. Able to force their way through ice up to 35 ft (10.7 m) thick, icebreakers have been important in keeping northern waterways open. |
