The sail according to the invention is especially designed to ensure optimum aerodynamic performance of the same, characterized in that it is shaped like an aeroplane "wing", including means for stowing/deploying the same. To do so, the sail can be deployed horizontally, using two pairs of vertical winders and the corresponding straps to guide the sail through the supporting structure thereof, or it can be deployed vertically, via a platform having a "wing"-shaped cross section that can be moved vertically along the axis of the mast, and to which the sail itself is connected, which can be raised using worm gears or hydraulic means. |
