How does an inducer work???
it adds hardware to the front of the mast (via a bolt through the mast) and uses cleats somewhere to force the mast to over-rotate.

No Without the main (sheeted), but you travel out a few inches (or more) to depower. This will cause you to point less (directly into the wind) but will help you spill off wind, and not gethit so hard when a gust of wind blows
