Not sure if anyone asked this question here but how do you plan to transfer the load of the wings/sails to the structure of the vessel?

A medium containership that weighs 150 tons moving at 20 kts has a lot of energy. If the wing is providing 10% of the propelling force, it’s like pushing/pulling 15 tons.

You need to transfer that to the structure of the ship, which may not be built to support that kind of stress.
