ABSTRACT:
A sailboat sail includes a sheet of material that contains stretchable webs that assume a planar orientation when placed against a planar surface, but which can stretch into a sail or airfoil orientation when mounted to a sailboat and exposed to wind loading. The sheet includes at least two webs of PVC vinyl laminated together between which is disposed a scrim of polyester yarn. The yarn is cross-hatched in a predetermined directional pattern. The sail has informational content, such as advertising, printed thereon or otherwise imparted thereto. A method for manufacturing such a sail includes providing a sheet of the aforementioned sail material, 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 sheet may be cut before or after the information is imprinted thereon.
