I'll second Wayne's comments below. When you let out the mainsheet on a run, a side pull develops as much as a down pull. Audasea is rigged with a downhaul, vang and mainsheet. With a downhaul at the gooseneck, the vang is only used off the wind. Also, I now have a snap shackle on the mast end of the vang, and can move it out to the toe rail, to give it even more downward pull, and where it doubles as a preventer. But like Bill's spinnaker, I'd only do that on a long run. Otherwise, you would have to go forward to switch it on every Jibe.
