[quote=leeboweffect][quote=saltlife77]I have been following this thread because I sail a Nacra 450 which is boom less and I am never 100% sure I am using the right spot on my clew plate for the prevailing wind conditions. Anyone have a good rule of thumb??[/quote]
For upwind and particularly upwind in high wind hang your mainsheet more forward (towards the mast). For downwind and particularly downwind in light wind hang you mainsheet more to the rear (away from the mast). As it seems we are learning here the optimal settings to use are very boat and geometry dependent, front hole your boat may not be front hole on another 450 if the sailmaker moved the clew plate.
Note that this adjustment is a finesse thing and if all your doing is day sailing put it in the middle and forget it.[/quote]
