Abstract
A ship's hull has a general frame form defining a bottom surface and two side surfaces. The bottom section of the hull comprises a substantially vertical wedge-formed portion, which extends vertically downwards in the region of the lowest part of the bow portion of the hull. The bow portion follows in horizontal sections, at and below the design water line of the ship, a substantially continuous curved arc. The stem line of the bow extends downwards/rearwards in a small angle to the horizontal plane, in order to enable ice-breaking by means of bending.
