one of the world's oldest major ocean races for sailing yachts, a 2,225-mile (3,580-kilometre) event run from various California harbours to Honolulu, Hawaii. It was first held in 1906 and made a biennial event in 1939 to alternate with the Bermuda Race. Since 1941 the race has been from San Pedro, Calif. (Los Angeles' harbour), to Diamond Head Buoy, off Honolulu. Since the course is mostly downwind and there is no limitation on overall length of vessels, the race is notable for the speeds attained.
