A "V"-shaped sail is mounted to flexible tubular members. The tubular member s are permitted to flex as wind speed increases. This lowers the effective centre of effort and the area of the sail and increases the stability of vessels and vehicles to which the sail is mounted without the need for operator involvement. The sail frame is mounted to a "Y" shaped yoke having a cylindrical stem. The stem is inserted into a locking base that permits rotation of the stem in 30 degree increments while preventing the st em from being removed from the anchor while the sail is set at an operating angle. T he locking base can be mounted permanently or temporarily to the vessel and vehicle. On e unique aspect of this invention is that no lines (sheets) or similar apparatus are required for any operational function of raising, lowering or sailing this sail kit.
