    Depends on the kind of sail. If they’re using any kind of spinnaker or kite sail, it requires human hands.

      Maybe read the article? It’s talking about a new kind of sail that’s literally a giant kite attached at the end of a line and kept flying hundreds of feet in the air above the ship by computer control. Not a spinnaker or kite sail; something closer to a parafoil.
