The Algoma Mariner arrived Duluth on Wednesday afternoon, August 2, 2017, with salt she began to discharge shortly after tying up at the North American Salt Company dock.
The Algoma Mariner arrived Duluth at 2:50, Friday afternoon on August 7, 2015. This is her 5 trip to the Twin Ports since she was built in 2011.

The Canadian flagged Algoport was built in 1979. Since 1996, she made 13 trips to the Twin Ports, 11 of them in 2000 and 2 in 1997. In 2007, Seaway Marine Transport decided to build 2 new self unloading forebodies in China and attach those to the refurbished after ends of the Algoport and Algobay. In June, 2009, the Algoport, under her own power, sailed to Balboa, Panama. There a tug took over and began towing the Algoport across the Pacific Ocean to China. The Algoport broke in half and sank in September, 2009 in the China Sea (the tug was able to disconnect before the Algoport sank). (pictures taken August 21, 2011 as the Algoma Mariner was arriving for her first visit to the Twin Ports. More information here.
The cargo hold and bow of the new boat had already been built and was waiting for the after end of the Algoport. When that was not possible, it was decided to build a new after end and connect it to the other already built pieces. I am not sure about all the legal definitions, but with that decided, the new boat became an entirely new vessel, or at least, a vessel made with all new material. I do not know how this new plan affected the original design of the boat.
Where the name came from
The Newbrunswicker was built in 1963 and was renamed the Grande Hermine in 1968. In 1972, she became the Canadian Mariner. That vessel was scrapped in 2008. The entire Upper Lakes Group fleet, of which the Canadian Mariner was a part, was sold to Algoma Central in early 2011. The Canadian Mariner was listed as a part of the sale but it must have been in name only. The boats in the sale were renamed with Algoma replacing Canadian. Perhaps this new vessel was to have kept the name Algoport, but at any rate, when the Algoport went down, the new build became the Algoma Mariner.
Go here to see pictures taken by Denny Dushane when the boat was on her way to Duluth on August 19, 2011.
Here are some additional notes Denny was kind enough to add: Her first cargo and load was iron ore pellets from Port Cartier, Quebec for Hamilton, Ontario (ArcelorMittal/Dofasco Steel Dock) where she arrived on August 7, 2011 to unload. Afterward, she spent 11 days in Hamilton for repairs I think to her engines, before finally departing on August 18 for Superior and the Twin Ports. She has had one noticeable change already and that is her port of registry "now reads as PORT COLBORNE where before, it was Toronto." The change in port of registry occurred sometime while she was in Hamilton getting repairs done to her engines. I also heard just this morning on boatnerd that, "the port of registry change may be related to the fact, that she is due to be christened at Lock 8 of the Welland Canal when she returns back downbound in a few days." The wife of the current mayor of Port Colborne, Ontario is scheduled to be the ship’s sponsor and will be doing the christening of the vessel in a few days.


  1. Paul from St. Paul says:

    Thanks for the pics of the new boat Ken!

  2. Hello – Algoport was one of my family’s favorite ships as we saw her launched at Collingwood in 1979. My brother and I even wrote a small book on our association with Algoma and the Algoport.
    Here’s a link to an interesting article describing the tow event:

  3. i am so anxious to see this boat come under the bridge. thanks to ken’s camera we can all witness the event!

  4. Boatnerd has lots of pictures in the news photo gallery of her entering the seaway, taken by local photographers.

  5. Also, Algoma updated the Equinox Class video after they purchased the ULS fleet:

  6. The Canadian Mariner listed as part of the sale from ULS to Algoma is the same new vessel due at Duluth in a few days. She was already almost completed at the time of the sale and was slated to be the second vessel to carry the Canadian Mariner name. Algoma chose to change that name when they absorbed the ULS fleet.

    The arrival of the Algoma Mariner on the Great Lakes is an extremely significant event: she’s the first new Lakes-capable, Seaway-sized ship built for a Lakes shipping company since 1985. She’s a brand new ship from the keel up and her stern end is actually of an entirely new and modern design. Her wheelhouse, accomodations block, self-unloading system, engine room, aft-end hull shape, rudder, and propeller are very similar to the high-tech “Equinox” class of newbuilds that are currently being built in China, at the same yard as the Algoma Mariner, if I’m not mistaken.

    Those new “Equinox Class” lakers will come online for Algoma in 2013, but the Algoma Mariner is a pretty good preview. The only differences that I see between the two types is that the Algoma Mariner is designed and classed for the Great Lakes as well as Coastal ocean trades, similar to the Algobay (in both her old and new configurations) or CSL’s Atlantic Superior, Atlantic Erie, etc., while the Equinox ships will be full-on dedicated lakers, replacing ships like the recently scrapped Algontario and Canadian Ranger or the soon-to-be retired Algocape and Algosteel. The Algoma Mariner has a slightly flared upper bow and a bulbous bow at the waterline, while the Equinox ships will have a straight, cylindrical bow like the Algolake or CSL’s forebody replacements (CSL Niagara, CSL Laurentien, etc.). The new Equinox self-unloaders also appear to have a different self-unloading boom design which is an enclosed box-shaped tube instead of an open triangular truss like those aboard the Algoma Mariner and most current self-unloaders.

    The latter part of the construction and finishing of the Algoma Mariner, as well as her journey from China to the Lakes, is being documented at this great page, I think by a crewmember: Entries go all the way back to April and there are tons of interesting photos and lots of information. Perhaps you could contact the author to see if you can use one of the shots of her there – he or she may be on board the vessel still and would perhaps not be averse to a little PR visit from the Duluth Shipping News. Photos have also shown up of the Mariner on and on her way into the Seaway on August 4th and 5th – photographer Jean Hemond got a particularly good aerial shot of her going under a bridge at Quebec City – he has a website at with a “Contact” page (the rest of it’s in French).

    Canada Steamship lines is also building a few totally new Lakers, due to come online next year. Their design is called the “Trillium” class, info and illustrations on this page, which they say will be updated often as construction progresses:

    And lots of great info (illustrations, photos, videos) about Algoma’s new Equinox Class gearless bulkers and self-unloading Lakers, due in 2013, here:
