I have a 4'x10' flatbottomed boat. Of the 40sq./ft. I cover 45% in solar to make a modest trolling motor go 6-7mph. Weight with myself, wife, battery, cells, misc. gear: 300lbs.

Solar ain't gonna get it on a cargo ship weighing 165,000 tons and a couple of football fields long.

Flat bottomed boats they make the rocking world go round.

Maybe something like diesel-electric that they use with trains with solar panels providing some of the electricity is a more realistic thought.

Batteries are part of what I said, which you seem to be ignoring. A ship that huge could hold some huge-ass batteries to power the bigass motors. Sodium-ion batteries would be the ideal solution with presently available technology.

Nowhere near the power density needed to get the job done
