AUCKLAND, New Zealand -- Seattle's OneWorld Challenge achieved something Friday that the world's best sailors have not done for more than seven years.

	Seattle's OneWorld, right, has the edge on Alinghi of Switzerland as the two boats jockey before the start of their race Friday.

OneWorld's win over Alinghi by 10 seconds on the second day of the America's Cup gave the Swiss syndicate's braintrust of Russell Coutts and Brad Butterworth their first loss in Cup races since April 12, 1995.

Australian Peter Gilmour, sailing in his fifth America's Cup, skippered the OneWorld yacht. Aussie compatriot James Spithill, 23, was at the helm.

One World led Alinghi across the start line and around all five marks on the 18.5 nautical mile course. Its largest lead was 22 seconds at the first, second and fifth marks. OneWorld led by 10 seconds at the fourth mark and at the finish.

There are now doubts about the Swiss yacht. Alinghi is 1-1 and among three teams with one point from two races. It is a win behind the American teams Oracle and Stars & Stripes, which lead the challenger series with two points apiece from two wins.

OneWorld, a syndicate backed by Seattle telecommunications magnate Craig McCaw and Microsoft co-founder Paul Allen, is 2-0 but was stripped of a point before racing started by the America's Cup arbitration panel.

Oracle, from San Francisco, and Stars & Stripes, the New York syndicate of Cup great Dennis Conner, both posted their second wins Friday from two race starts.

Oracle beat Mascalzone Latino by 2 minutes, 3 seconds, and Stars & Stripes upset reigning challenger series champion Prada by 35 seconds.

Earlier in the day, Prada announced Doug Peterson was removed as the syndicate design director of the Italian yacht.

Stars & Stripes hit the start line 5 seconds ahead of Prada and built its lead to 32 seconds at the first mark. The lead reached 54 seconds by the third windward mark and Stars & Stripes, with Ken Read at the helm, went on to win.

"It may have looked a little bit on the easy side but from onboard the boat, I can tell you it was anything but easy,'' Read said. "We got a couple of good shifts early on and when you have a bit of a breather it's not quite as stressful.''

Sweden's Victory Challenge, which waited four days through byes and race postponements to make its Cup debut, opened with a win over Le Defi of France.
