Driving force at different sheet angles for various angles of Incidence. Omega 14 sailboat.
So what is remarkable about this? I'm not sure. If this is correct you wouldn't be hurt too much if you simply left the car for the jib sheet an inch or so forward of middle of the track on the omega. The thing that always makes these theoretical ideas somewhat dubious is that the design of the sail, the tension on the halyard and even the sea state influence the optimum conditions for sail trim. It is much more prudent to look at how the tell-tails are flying and the slot between the main and the jib before considering moving the fair-lead for the jib.
