A sailboat sail and method of manufacture thereof, the sail material being chosen from a group of materials which lay substantially flat at all points when laid against a planar surface but which stretch under wind loading when attached to a sailboat to assume the conventional airfoil shape desirable of a sail. The sail has informational content such as advertising or other messages printed or otherwise imparted thereto. One method of providing such a sail includes the steps of providing a flat sheet of stretchable material having physical properties capable of withstanding conventional wind load-induced forces in near-shore sailing conditions, printing on one or both sides of the sheet information content to be displayed while the sail is mounted upon a sailboat, and cutting the sheet into the shape of a sail. The steps of printing and cutting may be transposed.
