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.

Claims

1. A sail formed by a process comprising steps of:

providing a sheet of material containing stretchable webs that lay substantially flat when disposed against a planar surface, but which are capable of stretching under wind loading to assume a sail or airfoil shape, the sheet including at least two webs of PVC vinyl laminated together between which is disposed a scrim of polyester yarn, the yarn being cross-hatched in a predetermined directional pattern, the sheet of material further including an opaque barrier sheet disposed between the scrim and at least one of the webs of PVC vinyl;

printing informational matter onto the sheet; and

cutting the sheet into the shape of a sailboat sail.

2. The sail of claim 1, wherein the sail is at least one of a headsail and a mainsail.

3. The sail of claim 1, wherein the information matter is printed onto the sheet by printing the informational matter onto an outer surface of at least one of the web of PVC vinyl.

4. The sail of claim 1, wherein the weight of the sheet is in the range of 10 to 30 ounces per square yard.

5. The sail of claim 1, wherein the sheet of material is opaque.

6. The sail of claim 1, wherein the informational matter is printed onto the sheet by printing the informational matter on both sides of the sheet.

7. A sail comprising:

a sheet of material in the shape of a sail adapted to be functionally employed on a sailboat, the material containing 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 of material including at least two webs of PVC vinyl laminated together between which is disposed a scrim of polyester yarn, the yarn being cross-hatched in a predetermined directional pattern, the sheet of material further including an opaque barrier sheet disposed between the scrim and at least one of the webs of PVC vinyl; and

printed informational matter disposed on at least a portion of at least one surface of the sheet.

8. The sail of claim 7, wherein the printed informational matter is disposed on both sides of the sheet.

9. The sail of claim 7, wherein the informational matter includes at least one of textual information and graphics.

10. The sail of claim 7, wherein the sheet of material is opaque.

11. A sail formed by a process comprising steps of:

providing a plurality of sheets of material, each sheet of material containing stretchable webs that lay substantially flat when disposed against a planar surface, but which are capable of stretching under wind loading to assume a sail or airfoil shape, each sheet of material including at least two webs of PVC vinyl laminated together between which is disposed a scrim of polyester yarn, the yarn being cross-hatched in a predetermined directional pattern, each sheet of material further including an opaque barrier sheet disposed between the scrim and at least one of the webs of PVC vinyl;

printing informational matter onto each sheet; and

assembling the plurality of sheets into the shape of a sailboat sail.

12. The sail of claim 11, wherein the adhesion strength of the two webs of PVC vinyl when laminated together is 20 pounds per two inches of length.

13. The sail of claim 11, wherein each sheet of material is opaque.

14. The sail of claim 11, wherein the informational matter is printed onto each sheet by printing the informational matter on both sides of each sheet.
