Let’s look at these from a different perspective . . . whether they can escape the inland seas shared by the US and Canada or not.  The maximum size the Seaway aka Highway H2O can accommodate is 740′ x 78. x 30.’

So Kaye E. Barker . . . 767′ x 70′ x 36′ . . . Nope.    But when she first came off the ways in Toledo in 1951, her loa was 647′ and she had no self-unloader, so back then she could have,


although there was no St. Lawrence Seaway then either.  So Nope again. But she was not lengthened until 1976, so Yes.  Her tonnage capacity is 25,900.


Mississagi comes in at 620′ x 60′ x 35,’  so if she’s carrying a partial load . . . maybe.  She came out of the River Rouge in 1943.  Her capacity . . . 15,800 tons.


In photo #2 above and the one below, notice the RenCen of Detroit.


American Mariner came out of Buffalo in 1979 at 730′ x 78′ x 45.’


So with a light load, yes.


Her capacity is 37,200 tons.


I don’t know if she ever leaves the Upper Lakes.


Chemtrans Elbe is a saltie, so obviously she’s a global traveler.  She was built in Korea in 2009 and measures 423′ x 75.’


Edzard Schulte was built in China in 2011, 475′ x ’75.’
