Do you see a problem, Sparky?
On the Mississippi you have issues of bridge heights, channel depth less than 36 ft., turns in the river which an 890 ft. ship cannot maneuver, etc. In short, no way.
>>>Do you see a problem, Sparky?
You’re not thinking enough... how ‘bout flocks of Nyan cats and unicorns all tethered to the ships picking them up, and flying them in to their destinations...
You forgot 1 other important fact. The ship will draw even more depth from being in fresh water. It might even sink! j/k
