The 8th Louis Vuitton Cup was held during July and August 2013, in San Francisco, California, United States of America. The three contenders were Artemis Racing (Sweden), Emirates Team New Zealand (New Zealand), and Luna Rossa Challenge (Italy). After a preliminary round robin to determine seeding, Artemis Racing was eliminated in the semi-final round by Luna Rossa Challenge by four races to none. In the final, Emirates Team New Zealand beat Luna Rossa Challenge by seven races to one, and went on to challenge Oracle Team USA for the 2013 America's Cup.

Round Robins The three yachts were scheduled to race ten times each, match-racing each competitor five times on a seven-leg course, with the winner of the Round Robins advancing to the final and the other two advancing into the semi-final.

On May 9, 2013, Team Artemis Racing's main boat capsized in strong winds, resulting in the death of crewmember Andrew Simpson. Artemis Racing forfeited its ten Round Robin races, entering the competition in the semi-finals stage.

Per rules 60.5 and 44.1c, the Artemis boat was deemed to have abandoned each race after the event had run for 10 minutes. While the Emirates and Luna Rossa boats earned black flag victories against Artemis, both boats chose to run a five-leg course for some (Luna Rossa) or all (Emirates, including one seven-leg) of these black flag races. Emirates and Luna Rossa only raced nine times, each forfeiting their final race against the missing Artemis as it could not change the final first-second standings of the Round Robins.

Emirates Team New Zealand won the Round Robins with nine points (4 race wins, 5 forfeit wins) to Luna Rossa Challenge's four points (4 forfeit wins) and Artemis Racing's zero points.
