For the improvement of the manoeuvrability of an ice-breaker, the foreship P of which is formed in pontoon-like manner with an obliquely forwardly rising underside which carries ice-breaking means at its sides, the ship's hull R is equipped on both sides over the entire length of the ship with balcony-like sidewalls 1, 1' of which the lower sides 2, 2' of the balcony drop away obliquely downwardly and lie at the level of the line of flotation SWL in such a way that on turning of the ship they break away the ice edges. Furthermore, the lower side of the bows is broader in the region of the ice-breaking means than the line of flotation of the following hull of the ship, in order to provide a clearance between the ice edges and the ship's hull. <IMAGE> |
