The course of the vessel in relation with the wind is an angle between the direction of the wind and the midship line of the vessel. One of the most widespread use of the wing is its application in the wind-driven ship. But these ships are not so fast. But there also is an alternative way to use wind for ship movement despite wind speed and stream force – the application of Magnus Effect, which is the result of mutual impact of the physic phenomenon, such as Bernoulli effect and creation of border layer around streamlined object. Using this effect, the first rotor vessel was created. In 1980s more complicated form of turbo sail was developed by French engineers under supervision of oenologist Jacques Yves Cousteau. In comparison with the best of the usual sails, the turbo sail provided 3,5-4 larger propulsive coefficient. It was supposed to install turbo sails to the tankers, bulkers and the large ships to decrease fuel consumption rate. Nowadays there are attempts to put rotor sails into mass usage. The rotor sails give possibility to save 30-40% of fuel at 16 knots speed. The experience of German shipbuilders will show if it is useful to develop the sails, working in application of Magnus effect. We hope, that in future the world navigation will apply the principle, described by the talented German scientist more than 150 years ago.
