An icebreaker hull having laterally projecting hull components which define inclined upwardly and rearwardly sloped faces arranged in part above and in part below the vessels normal water line, and each hull component further including a longitudinally extending face cooperating with the inclined face to define a cutting edge. At least a second pair of similar projecting hull components adjacent the first components to define a second cutting edge downstream of the first cutting edge. One or more of these hull components may be movable from and to positions where they are stowed in streamline relationship to the hull.

In an icebreaker having a hull with a forebody and a horizontally extending water line defining hull portions above and below said water line, the improvement to such hull forebody comprising first and second laterally projecting hull components, said first component having an inclined face for engagement with the ice to be broken, said face being inclined upwardly in the forward direction, and said face including a portion above and a portion below the water line, said first projecting hull component further including a longitudinally extending lateral face with portions both above and below the said water line and cooperating with said inclined face to define a first cutting edge, and said second laterally spaced projecting hull component being located adjacent said first projecting component, said second component also including a said longitudinally extending lateral face and a said upwardly inclined face so as to define a second cutting edge downstream of said first cutting edge.
