Its honestly not a bad idea. When Sails fell out of fashion, canvas was the height of technology, nobody gave a fuck about emisions and tanker fuel was cheap AF.
If the owners of tanker/container fleets can see a $20,000 reduction a year in fuel costs by fitting a modern well designed $10,000 sail that costs $5000 a year to maintain. They will.
If multinational trillion dollar industries can find ways to save money AND go green at the same time. Good.
