Technologies are described herein for sailing wing for a vehicle such as a sailboat. As described herein, a sailing wing includes a main sail and a control surface. The control surface is rotatable around a hinge. When deflected, the control surface using force imparted on the control surface by the wind causes the main sail to rotate about a pivot axis, creating thrust.

The presently disclosed subject matter relates to an airborne device that includes at least three airfoils and a linking device. The airfoils are connected together by first cables, each airfoil further being connected to the linking device by a second cable. The linking device being connected to a third cable intended for being connected to a base. The first, second and third cables being tensioned when the airborne device is placed in the wind. The device further includes for each airfoil, at least one first rigid lever element connected to the first cables and the airfoil by a first electromechanical linking system having at least one degree of rotational freedom and designed for modifying the orientation of the first lever element relative to the airfoil.

The drag sail has multiple ropes (2) for attaching to a ship (3). A profiled plastic structure in wave form or zigzag is formed by transverse ribs (4). The transverse ribs run together transverse to the wind direction at a distance and exhibit any form e.g. circular, semicircular or square, in shape. The transverse ribs receive the ropes at its end points, and additional ropes (2A) in a middle region. The drag sail is made of plastic or cloth.
