ABSTRACT OF THE DISCLOSURE A cargo-carrying articulated ship system having icebreaking capa- bilities is provided herein. It includes of a powered cargo-carrying ves- sel having an icebreaking hull from, a bow and a stern, and a powered loco- motive vessel having an icebreaking hull form, a bow and a stern. In addi- tion, a connection system is provided for connecting the cargo-carrying ves- sel and the powered locomotive vessel at concave and convex respective bow and stern confugurations to provide an articulated cargo-carrying locomotive vessel and vessel system. This connection system comprises winches secured to the powered locomotive vessel with lines therefrom tied to the cargo- carrying vessel and is operable by interrelated winding-in and paying-out of the lines by operation of the winches. This controls lateral movement of the cargo-carrying vessel relative to the locomotive vessel. Not only does this system minimize longitudinal movement between the locomotive ves- sel and the cargo-carrying vessel, but it also positively provides indepen- dently operable cargo-carrying vessel control means which are operable inde- pendent of the control means for the locomotive vessel. Thus, the cargo- carrying vessel is maneuverable in lateral directions independently of the direction of movement of the locomotive vessel. Thus a cargo-carrying ship used in ice infested waters is provided having optimal split between cargo- carrying capability and propulsion capability.
