Weight of batteries is a big issue with ships. Vaclav Smil calculated diesel is 20x dense, turning 5000t diesel fuel for Asia-Europe trip to 100000t battery which is not economical.

I wonder if a hybrid can reduce that problem, i.e. a hybrid battery/sail, or even a hybrid battery/windmill system.

A windmill would help both push the ship and generate power to the batteries.
