[quote=erice]be aware that that tuning guide is for the later nacra 5.2 with swept spreaders
they made a few hundred of those
most of us have the 5.2 that nacra made in thousands, with straight spreaders...
i'd say forget the mast bend stuff about mast rotation on the older 5.2
to me it's all about aerodynamically smoothing the entry of the air to the sail
to do that, set your mast rotation so that the stainless rotator arm is pointing back to the shroud
then leave it along
if you want to tweak further against other 5.2's in 1 design racing set the wishbone to point slightly ahead of the shroud in light wind, slightly behind the shroud in strong wind, fully uncleated downwind and fully cleated in survival winds[/quote]
