ABSTRACT OF THE DISCLOSURE The prow of the ship with a lower power requirement in open and ice-covered water has a front surface which is forwardly inclined at the top over the entire beam of the ship with marginal cutting edges, preferably on rod-like profiles. The front surface passes into an underwater prow part with frames which are Y-shaped at the bottom. The cutting edges above the waterline can forwardly pass into two catamaran-like stems, the front surface being curved in the longitudinal direction. The front surface is carried by thwartships frames, which are horizontal at the bottom in the central part of its longitudinal extension, below the construction waterline and approximately forms a plane there. In the midships longitudinal direction an ice-cutting central skid is provided on the prow. Even in the case of widely varying ice characteristics, favourable conditions are provided for breaking out one-part ice floes. The one- part ice floes are split up underwater centrally into two halves floating laterally under the fixed ice layer, which largely prevents crushing into a large number of pieces. (Fig 7).
