A water-wiping apparatus for wiping standing water from a curved surface has a flexible panel of a first height, with an upper long edge of a first length and a lower long edge of a second length, greater than the first length, the upper long edge centered on the length of the lower long edge, a sub
A water-wiping apparatus for wiping standing water from a curved surface has a flexible panel of a first height, with an upper long edge of a first length and a lower long edge of a second length, greater than the first length, the upper long edge centered on the length of the lower long edge, a substantially rigid handle having a length substantially equal to the first length attached along the upper long edge, and a lip formed along the lower edge, extending to one side of the flexible panel and ending in a sharp line at the end away from the flexible panel.

1. A water-wiping apparatus for wiping standing water from a curved surface, comprising:a flexible panel of a first height, with an upper long edge of a first length and a lower long edge of a second length, greater than the first length, the upper long edge centered on the length of the lower long
1. A water-wiping apparatus for wiping standing water from a curved surface, comprising:a flexible panel of a first height, with an upper long edge of a first length and a lower long edge of a second length, greater than the first length, the upper long edge centered on the length of the lower long edge;a substantially rigid handle having a length substantially equal to the first length attached along the upper long edge; anda lip formed along the lower edge, extending to one side of the flexible panel and ending in a sharp line at the end away from the flexible panel:wherein each end of the upper long edge of the flexible panel is joined to the closest end of the lower long edge by a smooth, curved shape, convex relative to the flexible panel in at least a portion, the shape mirrored at each end of the panel. 2. The water-wiping apparatus of claim 1 wherein the lip has a triangular cross-section in a plane cutting the panel orthogonal to the length and parallel to the height. 3. The water-wiping apparatus of claim 2 wherein the lip joins the flexible panel at an angle equal or less than thirty degrees. 4. The water-wiping apparatus of claim 1 wherein the handle is symmetrical about a central plane common to the panel, and has two sides corresponding to opposite sides of the panel, further comprising an upper and a lower longitudinal ridge on each side of the handle, the ridges spaced apart to form a longitudinal groove to engage a user's fingers or thumb, providing a sure grip for the user on the handle. 5. The water-wiping apparatus of claim 4 wherein the upper longitudinal ridge on each side of the handle extends from the central plane of symmetry to a greater extent than does the lower longitudinal ridge. 6. The water-wiping apparatus of claim 1 wherein the lip extends to both sides of the flexible panel. 7. The water-wiping apparatus of claim 1 wherein the handle further comprises an interface for attaching a handle extension. 8. The water-wiping apparatus of claim 1 wherein the opposite ends of the handle are rounded, presenting a substantially curved outward surface toward the ends of the apparatus. 9. A blade insert for a water-wiping apparatus comprising:a flexible panel of a first height, with an upper long edge of a first length and a lower long edge of a second length, greater than the first length, the upper long edge centered on the length of the lower long edge;a handle interface along the upper long edge adapted to join the flexible panel to a rigid handle; anda lip formed along the lower edge, extending to one side of the flexible panel and ending in a sharp line at the end away from the flexible panel;wherein each end of the upper long edge of the flexible panel is joined to the closest end of the lower long edge by a smooth, curved shape, convex relative to the flexible panel in at least a portion, the shape mirrored at each end of the panel. 10. The blade insert of claim 9 wherein the lip has a triangular cross-section in a plane cutting the panel orthogonal to the length and parallel to the height. 11. The blade insert of claim 9 wherein the lip joins the flexible panel at an angle equal or less than thirty degrees. 12. The blade insert of claim 9 wherein the lip extends to both sides of the flexible panel.
