I'm just guessing. LOL
Now I see what you mean about the load.
I don't have the slightest idea of how the operations of these container ships are handled.
Most of the pictures you see show them fully loaded with the containers stacked solid, fore to aft, port to starboard and up to a stack as much as five high.
I had assumed they were loaded to full capacity at one port and completely unloaded at another port.
But maybe this ship has picked up a light load at one port and is proceeding to another port to load more.
Or it has unloaded most of the containers at one port and has a few left for another port.
I haven't seen any pictures of a completely empty container ships nor any as lightly loaded as in your pictures.
Sort of related to this, but my idea of the Steerage quarters on ships like the Titanic would be that they were loaded to near or full capacity for the westbound voyage to America.
But who would be going Steerage on the eastbound return to Europe ?
Tourists on a lower budget than those on Second or First Class ?
Were there any returning to their homeland after maybe not having luck in America ?
Spell Check kept trying to put "Steerageble" instead of "Steerage" when I first typed this. LOL.
