The present invention relates to a ship for navigating in icy waters, provided in the stern area 3 with a wedge 10 which extends from bottom 4 of the ship downwards transversely to the ship. Wedge 10 is defined by a first surface 11 inclined towards the bow and by a second surface 12 inclined towards stern with respect to a horizontal plane. These two surfaces are connected to each other forming a lower edge 10' of wedge 10. The wedge is at least partially arranged below waterline WL of the ship. The first inclined surface 11 is dimensioned in such a way that in the case of forward motion, the first surface, hit by the flow of water, generates a lift force such as to modify the longitudinal trim of the ship acting as a trim wedge. The second inclined surface is dimensioned in such a way that, in the case of reverse motion in icy waters, it engages the ice first and for the ship acts as a rising chute above the ice itself. The wedge crushes the ice by bending thanks to the weight of the ship itself once the stern of the ship has slid over the ice.
