Launch Date: Forebody: November 2009; Entire Hull: Fall 2010

Commissioned: August 2, 2011


The Algoma Mariner was constructed as a self-unloading bulk carrier for Algoma Central Corporation. The vessel was originally intended to be a forebody replacement for Algoma’s Algoport, similar to the project completed on the Algobay. The Algoport sunk while under tow to China for her new forebody, and the decision was made to construct a stern section for the new hull.

The Algoma Mariner had a similar appearance to the Radcliffe R. Latimer, but her cabins appear similar to Algoma’s Equinox class ships.

Her self-unloading equipment consists of a dual-hold belt leading to an aft loop-belt system to a 262′ deck-mounted boom.


  • Diesel Exhaust Scrubbers installed, February 2020.

Her Story

On November 7, 2007, Algoma Central and Upper Lakes shipping announced plans to build two new forebodies to attach to existing sterns as part of a $125 Million contract with the Chengxi Shipyard in Jiangyin, China. The Algoport and her near sister Algobay were selected to receive the new forebodies, with the Algobay being the first ship to be taken to China for rebuilding. On April 3, 2009, the Algoport was put into drydock at the Port Weller Dry Docks at St. Catharines, ON, for necessary hull strengthening for the voyage to China.

While under tow of the tug Atlantic Hickory while in the East China Sea, the tow encountered Tropical Storm DuJuan. The Algoport broke in two and sank in the storm, on September 6, 2009. There was no loss of life or pollution reported after the sinking, and Algoma Central announced on September 10, 2009, that a new stern section would be constructed to be attached to the new forebody originally built for the Algoport. The result would be the self-unloading vessel Algoma Mariner.

The new forebody was launched in November 2009, and the new stern section was constructed on the forebody while the vessel was in drydock, being launched in Fall of 2010. The vessel was laid down as Canadian Mariner {2}, being intended to operate as part of Upper Lakes Shipping’s fleet, but in February of 2011, Algoma bought out Upper Lakes, and the vessel was renamed Algoma Mariner. The completed hull departed China on June 4, 2011, arriving at Port Cartier, QC, on August 2, 2011, to load her first cargo.

The Algoma Mariner was formally christened on August 25, 2011, in a ceremony at Port Colborne, ON.

The Mariner was fitted with diesel exhaust scrubbers during the winter layup period in early 2020.

The Algoma Mariner continues to be an active member of the Algoma Central fleet, serving the Great Lakes and Atlantic ocean ore, coal, stone, grain, and salt trades.
