I've looked at 6 or 8 'big-name' or magazine-sponsored web pages, and none of them made sense. Your not only makes sense of the 'how', but explains the benefits more clearly, and even ways to leverage the technique to even greater advantage. Fantastic!! I hope you don't mind if I save this web page to refer Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2235103639410795945.post-33771220371957205522011-12-30T22:36:31.070-06:002011-12-30T22:36:31.070-06:00Great observation!

What you're seeing with your indicator at (I assume) the bottom of your mast is turbulence as the wind exits the sail, just like the vortex at the end of a 747's wing (and why they reduce this with winglet's). We know this is the exit because the flow is from the leach to the mast because you are sailing by the lee. As this is the exit, the wind cannot be reused.<brDougnoreply@blogger.comtag:blogger.com,1999:blog-2235103639410795945.post-77504645336926892482011-12-30T15:44:05.231-06:002011-12-30T15:44:05.231-06:00Your comment re-using the wind (Humming bird): I h...Your comment re-using the wind (Humming bird): I have wind indicator at the bottom of the sail - on lee sailing I find the most power at the right sail angle results when this indicator spins in a vortex- could this be the extra power from re-using the wind??
