A device for ice-breaking with a vessel has two functionally separate upper and lower elements of different widths. The upper, wider element is situated next to the water line for breaking unbroken ice, and the lower, narrower element is situated below the upper element and for transporting broken ice sideways and under the unbroken ice. The upper wider element has a flat lower portion abaft an inclining front part with a small frame angle and breaks ice downward when moving ahead, and a flat stern part with a small frame angle and breaks ice downward when moving astern. The lower element has vertical side portions which in the forebody and the afterbody have a marked wedge-shape and shove broken ice sideways. Transport of broken ice sideways and astern can be augmented by bow propellers and wing propellers.
