I would also say that far and away the best service for sailors is www.ikitesurf.com. If you want accurate and extremely detailed wind forecast and current info subscribe to this site. You will not be disappointed. They maintain their own sensors all over the country and have specialized wind forecasters for most areas. They do a great job because most of their clients are windsurfers and kiteboarders who rely on a super accurate forecast because a forecast that is off by 5 knots of wind can mean going riding or not.
