sunbvi,

As I recall the wind was light, maybe 5-10 knots from the west. I have no explanation for the wind shift, maybe the wind was funneling to the west off of Scrub then hitting Great Camino and becoming westerly but I would have thought the "low spot" between Lee and Cam Bay would have allowed the wind to continue thru.

My lesson learned was not to trust the wind to keep us safe from shore or other boats, even in the BVI's with the steady tradewinds. We've anchored in too many crowded places where you could tell many were not counting on a wind shift, a squall or other boats laying at anchor differently in light winds over night.
