That is correct. Roger used different length "hinges" or what looks to be loops that the battens are threaded through to create camber in an otherwise flat panel. The part I can't quite make out is if each panel is a separate piece threaded or attached to the battens or they are sewn together at the hinges, luff and leech. It looks like the hinges are consistent from panel to panel and may be joined together at the batten connection. I remember reading that each panel was easier to sew because you were only moving one panel through the machine at a time. I also read somwhere about the air that passes through the slots may be beneficial in terms of keeping the sail from stalling.

I have been looking over videos etc. Of Roger Taylors hinged panel design on Ming Ming II. I can't tell if the lower panels are completely separate or if they are sewn together into a one piece sail. By separate I mean that you could remove or replace a panel. How is the leech and luff connected at the batten ends? Thank you.
