Established in 1964, the Rolex Big Boat Series takes place annually on San Francisco Bay. In 2005, Rolex became title sponsor of this prestigious regatta which includes very competitive one-design and handicap racing. Widely recognized as one of the most important sailing events on the U.S. West Coast, this “granddaddy” of grand-prix racing attracts the top competitors and boats from across the country. The 2009 Rolex Big Boat Series will incorporate the Rolex US-IRC National Championship, where all competing IRC yachts will be eligible for the title.
