Zusammenfassung:The invention relates to a sail (2) including a fabric made of continuous warp and weft yarns. When the sail is in flight, first yarns, which are either warp yarns or weft yarns, extend in the anteroposterior direction (AP) of the sail, while the second yarns, which are either the weft yarns or the warp yarns, respectively, extend in the lateral direction (L) of the sail. In order to enhance the lightness of the fabric while retaining the mechanical strength performance thereof, the invention proposes that the resistance to deformation of the fabric along the second yarns thereof be higher, in particular by 10 %, than the resistance of the fabric along the first yarns thereof. For this purpose, the size and/or the number of the second yarns is strictly higher than the size and/or the number of the first yarns.
