A ship is equipped with a skeletonized bow projecting forwardly from the hull and comprising a trussed frame from which generally parallel corrosion-resistant cables extend from an elevation above water level to the level of the bottom of the hull. In the preferred arrangement, this frame carries individually powered ice cutting saws in an array materially wider than the ship, the saws being mounted for vertical and lateral tilting adjustment responsive to automatically functioning leveling devices and equipped with semi-circular guards. The saws cut beam-like strips of ice from which the cables break off and deflect sections of an ice floe.
