You do realize that none of those ships could get into any port, right? We've made modifications to accommodate that.
I tend to agree with you that putting a fixed sail on top of a container vessel won't fly.
Maybe ships would need to be smaller. I think the size of ships was mostly increased because it makes it more efficient. But if fuel is free, you could have smaller ships take direct routes instead of the layovers we do now. That might compensate for time lost as well due to lower speed.

This is a PoC not a finished product
