ABSTRACT OF THE DISCLOSURE A cargo-carrying articulated ship system having icebreaking capabilities is provided herein. The system comprises a powered cargo- carrying vessel having an icebreaking hull form, a bow and a stern, and a powered locomotive vessel having an icebreaking hull form, a bow and a stern. A connection system is provided for connecting the powered cargo- carrying vessel and the powered locomotive vessel together at concave and convex respective bow and stern configurations. The connection system in- cludes male junction elements (a semi-spherical projection and the nose of the towed vessel)/female junction elements (semi-cylindrical hollow verti- cal outlets in the stern of the towing vessel). These male/female junction elements restrain longitudinal movement between the connected vessels, yet permit relative vertical movement and allow relative rotational movement. The connection system also includes hydraulic cylinders secured to the lo- comotive vessel with lines secured to the arm end therefrom and tied to the cargo-carrying vessel. Interrelated pulling-in on one cylinder and slack- ing off on the other cylinder controls the lateral movement of the powered cargo-carrying vessel in relation to the powered locomotive vessel. This operation enables the powered cargo-carrying vessel to be manoeuverable in lateral directions independent of the direction of movement of the loco- motive vessel..Thus a powered cargo-carrying vessel for use in ice infested waters is provided having an optimal split between cargo-carrying capability and propulsion capability.
