The goal of the proposed invention is to enhance boats through the creation of a onebody boat or Catamaran with automatic controlled wing (or kite) type sail (better to say - without autopilot and altogether without any electronics). During the manoeuvring by wing type of sail there is not required the special skills for sailing that is why it is available for everybody. In case of moving with water screw the wing type of sail reveals the wing properties, which will be directed against the air counter flows and lifts the body up the water with the screen effect that increases the speed and hoisting capacity. However, in case of equipping with air air screw such sailing boat will flying as screen-plan. The automatic control mechanism intended for wing type of sail comprises the wing type of sail fixed to the rotatable and placed on the deck mast tilted to the body’s front side (stem) and equipped with weather vane, which has a wing profile and the angle between the wing type sail and rotatable mast equals to angle between the mentioned mast and deck surface due to which as a result of turning the weather vane the wing’s chord figures the cone surface, the generatrix inclination towards the stern is of maximum value and equals to the sum of the mast’s and wing’s inclination angles, but towards the stem post it equals to minimum value ***** it is horizontal and equals to angles difference between the mast and wing that equals to zero and onebody boat or Catamaran with mentioned equipment carries of drift. Technical description and technology of the making process of wing, weather vane and mast with regulation mechanism of its tilting, there will be on the time of contract registration (it is “Known-How”).
