Jib Battens
Tom, Many jibs or genoas have battens, and almost all of these are working jibs or racing "blades" with LP's of approx. 100% or less. The battens allow the sail to be designed with a minimum amout of leech hollow as well as to minimize leech flutter in higher winds. Roller furling genoas are generally not referred to as working jibs even if they are relatively small. Very few of these have battens. If they do then they are oriented vertically or are special roller battens.Bill Colombo, Doyle SF
