Yes, some companies are employing old-fashioned wind-powered boats with sails. As oil prices rise higher and higher, companies are looking for cheaper alternatives. For example, a French wine company has used a century year old boat to ship thousands of bottles of wine from France to Ireland.
German fishing boats fly kites to reduce their oil consumption. These can help reduce their fuel demand by up to 30% after a couple of years of research and development, currently it is around 10%. I would not be surprised to see more and more such kites to be implemented.
