The limiting size factor for Great Lakes shipping is the size of locks in the St. Lawrence Seaway. This ship is one of a new generation that absolutely maximizes the size for the lakes (or 'seawaymax'), leaving only a few inches on all sides when it's in a canal lock. It's not surprising that it scrapes occasionally. Currently the ship is sitting very high in the water, obviously empty.
The company struggled financially for many years, but in the late 1990's sold off the railway division and their forest land, becoming a maritime shipping company based in St. Catherines. It focuses on dry bulk shipping of grain, iron ore, salt and aggregates, maintaining a fleet of both self-unloaders (with cranes on board for unloding) and gearless bulk carriers (unloaded using dockside cranes). The Harvester is a gearless bulk carrier. A few more pictures tomorrow.
