But does the overall cost of these 'WindWings' recoup over the lifetime of cargo ship. Including the fact that they can now carry less cargo per trip. And the trip might take longer due to 'route optimizations'. Insurance is probably also going to be higher now that you have giant sails on top of the ships that makes it both more expensive but also i suspect less safe in rough seas(even when folded).
I feel that is the only true measure otherwise cargo ship builders are not inclined to build more of these.
