The first ends of each of the first and second arcs meet at a first point, while the second ends of the first and second arcs meet at a second point. A chord is essentially positioned between the first and second points dividing the panel into a first region and a second region in a lengthwise direction. The length of each region is greater than its width. The are of the panel is attached essentially between the tack and clew substantially along the foot chord of the sail. The first points of the arc are positioned substantially towards the tack and the second points of the arc are substantially positioned towards the clew.
