For a ship to be considered an icebreaker, it requires three traits most normal ships lack: a strengthened Hull (watercraft), hull, an ice-clearing shape, and the power to push through sea ice. Icebreakers clear paths by pushing straight into frozen-over water or pack ice. The bending strength of sea ice is low enough that the ice breaks usually without noticeable change in the vessel's wikt:trim#Noun, trim. In cases of very thick ice, an icebreaker can drive its Bow (ship), bow onto the ice to break it under the weight of the ship. A buildup of broken ice in front of a ship can slow it down much more than the breaking of the i ...
