Abstract: The invention relates to a watercraft having improved characteristics for travel in ice, particularly an icebreaker, supply vessel, cargo vessel or corresponding, which watercraft has a hull, which has at the stern portion a propulsion and steering arrangement, which is mainly responsible for movement and steering of the watercraft and which includes at least one skeg, in which is located at least one propeller device. In accordance with the invention, said skegs comprise two units located on different sides of the center line of the hull. Said propeller device is located at the stern end of the skeg. In addition, the skeg has between the propeller device and the hull of the watercraft, in the longitudinal direction on the skeg, one or more thruster devices to provide a water flow mainly transverse in relation to the hull.

Abstract: The invention relates to a watercraft having improved characteristics for travel in ice, particularly an icebreaker, supply vessel, cargo vessel or corresponding, which watercraft has a hull, which has at the stem portion a propulsion and steering arrangement, which is mainly responsible for movement and steering of the watercraft and which includes at least one skeg-like projection, in which is located at least one propeller device. In accordance with the invention, said skeg-like projections comprise two units located on different sides of the centre line of the hull. Said propeller device is located at the stem end of the skeg-like projection. In addition, the skeg-like projection has between the propeller device and the hull of the watercraft, in the longitudinal direction on the skeg-like projection, one or more thruster devices to provide a water flow mainly transverse in relation to the hull.
