The distance the boat has to cover is 11800 kilometers, and the truck covers only 54 kilometers. Taking that average of 12 times more usage from the table of sibling comment means the ship is still 20x worse.

But what if you apportion the fuel usage over the items transported? Presumably the ship carries far more items than the truck.

This is already taken into account: Shagie's table is based on [1], which is per kilogram-kilometer

I suspect they are underestimating how efficient ocean shipping really is.

Do you have any basis for that which I could refer to in discussion?
