Ships for navigating in icy waters are provided. Such ships include in the stern area a wedge which extends from bottom of the ship downwards transversely to the ship. The wedge may have a first surface inclined towards the bow and a second surface inclined towards stern with respect to a horizontal plane. These two surfaces can be connected to each other forming a lower edge of wedge. The wedge is at least partially arranged below waterline of the ship. The first inclined surface is dimensioned in such a way that in the case of forward motion, the first surface contacting the flow of water, generates a lift force in order to modify the longitudinal trim of the ship acting as a trim wedge. The second inclined surface also is shaped advantageously in the case of reverse motion in icy waters.
