Shrug, they been talking about this since the 90's...

If it was feasible and economically viable. It would have happened already.

The reason is because the company that operates a shipping vessel often doesn't own the ship--they charter it. It would be the owner that pays for the fancy wind propulsion systems but only the charterer would benefit from the reduced fuel costs. Owner-operators of shipping vessels sometimes do have a supplemental wind propulsion system.
