ABSTRACT:
This invention is an improved sail which uses wedge-shaped panels on the luff with warp threads running the length of the wedges. By properly proportioning the wedges, luff tension is distributed through the centroid of the [jib] sail triangle and thus controls draft position and leading edge flatness. The result is a broader wind range sail with longer optimum performance life.
