There are sailed powered logistics ships! Here’s a grain ship that just launched. There are also companies that produce inflatable or deployable sails to reduce fuel consumption in favorable winds.
Ultimately there will be a need for chemical energy or similarly dense energy to move a ship. The wind doesn’t always blow, and when it does it won’t always be in the direction you want. Nuclear is certainly an interesting option.
