An annual favorite in the bay, the SSS Three Bridge Fiasco is the biggest yacht race in the US west of the Mississippi River, with 300+ boats every year.  The race is a pursuit race (slowest boats start first), starts and finishes on the city front at the Golden Gate Yacht Club, and the course involves the Blackaller Buoy (by the Golden Gate Bridge), Yerba Buena Island/Treasure Island (Bay Bridge), and Red Rock (by the Richmond/San Rafael Bridge).  The marks can be rounded in any order and any direction, providing the crazy appeal of this race.
