Flettner Rotors

Wow - very cool. If these become common you all will be downloading GRIBS and using the same routing optimization software that us sailors are used to. Also VERY important - do not forget to shut the engine down when near other ships and tell them to get out of your way - you are SAILING :cool: If you get really good you can arrange to meet a sailboat while they are on port and you are on starboard :smiley:
