The Algoma Navigator moored in the channel to Toronto's turning basin.

If you look closely you can see this vessel has a long boom. Self-unloading bulk-carriers can swing out their booms, to unload their cargoes. Their holds have V-shaped bottoms, with a conveyor belt below them. When doors at the bottom of a hold opens the cargo starts to drop to the lower conveyor belt. The cargo is carried to some kind of lifting devices, which places it on the upper conveyor belt on the boom. Older bulk carriers that are not self-unloading still carry cargo, but self-unloading vessels are now more common. Lake vessels, which are not exposed to salt water, can remain in service for decades longer than a "saltie", and a considerable number of older vessels have been retrofitted with self-unloading machinery. The Algoma Navigator was retrofitted in 1997.
