The invention relates to a Flettner rotary sail (800) capable of turning about a vertical axis, and comprising an aerodynamic surface of rotation extending between a proximal end and a distal end, comprising, between its two ends, a plurality of sections centered on the vertical axis and extending along said axis between two parallel circular hoops, respectively of diameter 2r, and 2r2, the hoops being spaced apart by a distance 2h along the vertical axis, the shape of the aerodynamic surface of the section being defined by the revolution of a continuous meridian curve comprising, between the two hoops, a groove of radius r0 less than or equal to r1 and less than or equal to r2
