for the 2007 Valencia America's Cup. Barker started Team New Zealand's quest to take the Cup back to New Zealand by winning the challengers' 2007 Louis Vuitton Cup— beating the Italian Luna Rossa Challenge team 5–0 in the final after the previous elimination of the other 9 challengers. This was the first time that the Louis Vuitton Cup had ever been won without a race loss to the opponent. This gave Emirates Team New Zealand and Barker the opportunity to race the Swiss challenger Alinghi for the 32nd America's Cup. By winning Race 2 of the 2007 America's Cup against the Defender Alinghi, Emirates Team New Zealand ensured that the scoreline in the America's Cup would not show a clean sweep victory for the first time in fifteen years. Many experts believed Emirates Team New Zealand had a good chance of winning but finished the 2007 America's Cup with a 2–5 race defeat. Overall the 2007 America's Cup racing was close with the final race won by Alinghi, skippered by fellow New Zealander Brad Butterworth, with a winning delta of 1 second. Barker has participated in two defences and two challenges for the America's Cup. After the 2007 event, his record as helmsman in Finals was 3 wins to 10 defeats. In August 2013 Barker once again skippered Emirates Team New Zealand to victory in the 2013 Louis Vuitton Cup— beating the Italian Luna Rossa Challenge team 7–1 in the final. He set a Louis Vuitton/America's Cup speed record in race #7 of . Barker and Team ETNZ then went on to Challenge Americas Team Oracle in the 2013 Americas Cup Final and went on to lose the final. ETNZ at one point during the final series had won 6 of the first 7 races ultimately going on to lose by a score of 9–8. The largest comeback in Americas Cup history. A rift started to emerge between Barker and Team ETNZ's CEO Grant Dalton. Through 20 September 2013, Dean Barker's record as helmsman in America's Cup Finals stands at 11–15. With only one more race win needed for Emirates Team New Zealand to secure the Cup, Dean Barker will need one more America's Cup series to break even. Early 2015 saw Grant Dalton offer Barker a shore-based position in order to make room for a new helmsman, Peter Burling and a new skipper, Australian sailor Glenn Ashby. Barker refused
