Abstract

An ice-breaking vessel having a spoon-shaped bow portion and an obliquely downwardly/rearwardly extending reamer at each longitudinal side is provided with second reamers located above the water line, above the rear portion of the adjacent first reamer and extending further outward than the same. A plow-shaped extension projects downwards from the plane bottom of the vessel, and has a breadth less than the breadth thereof. The rearmost part of the deck of the aft portion of the vessel has a reduced breath, so two corners are formed at each side of the deck. The bilges at the bottom plating extend to the forward of these corners, while the bilges at the plow-formed extension extend to the rearward corners.
