alt Hacker NewsNo, but with wind it's possible. Either vertical windmills or sails with modern signal processing.
Honestly DJI and Boeing should get into this business. A boat's sail basically a plane's wing, aerodynamically speaking. They share a lot of similarities with endurance gliders.

Smaller boats sure, but ocean going cargo vessels? There are some serious challenges!
Try to approximate the area needed to generate e.g. 50MW propulsion. It would be measured in hectares.
Plenty of engineers exist in sailing who know all that and have studied this. Boeing brings nothing new if they get in. Well other than perhaps dollars, but that isn't the problem for the most part.
