M.V. CSL Niagara, which was delivered by Port Weller Dry Docks this past July, is the largest seaway capable vessel on the Great Lakes. The two self-unloader resulting was formulated by joining the aft end of M.V. J.W. McGiffin to a complete new forebody built and outfitted by PWDD. Beginning with the new forebody being floated out of the building dock, McGiffin was then docked and its old forebody was cut and floated off — the new forebody was re-docked and joined to McGiffin's stern shortly after. Taking advantage of new maximum seaway dimensions resulting in cargo lifts, the vessel was selected to celebrate strong links between Canada Steamship Lines and the Niagara Region.
