GBR Challenge suffered a defeat at the hands of Swiss yacht Alinghi in the Louis Vuitton Cup this morning.

Squalls streaking across the Hauraki Gulf in Auckland meant a two-hour postponement on both race courses before action resumed on the shorter, 12.5 mile Course B.

And once racing got underway, the wind died and massive wind shifts saw tacticians, sailors and Race Officers in a muddle.

Leg time limits saved OneWorld and Victory Challenge - who were losing their matches when the leading boats ran out of time to cross the finish line.

Luna Rossa and Alinghi beat the clock however, and both scored their fourth point in four outings in Round Robin Two.

All Flight Six matches were postponed without starting.

Italian yacht Luna Rossa beat fellow countryman Mascalzone Latino by one minute 42 seconds - a margin that betrayed what had been a very close race.

Alinghi got some lucky breaks as the course was re-configured and went over a mile ahead of GBR Challenge, with Titchfield's Andy Beadsworth at the helm.

The Swiss yacht just beat the time limit to cross the line seven minutes and 45 seconds ahead of the British boat.

After racing, the GBR Challenge submitted a Request for Redress, claiming the Race Committee made significant errors in its match with Alinghi.

At the post-race press conference, GBR Challenge skipper Ian Walker said his match with Alinghi was simply not a fair test of sailing.

"It wasn't much of a race. On the first beat we didn't tack, and on the next run we laid down on port," complained Walker. "We want to have good racing. Even if we don't win the race, we want to have a race.

"There's a number of errors ranging from where the course area was, the length of the course, as well as procedural errors...it's probably the first America's Cup race that's gone around an island since 1851."

It's interesting to note that both competitors racing on the same course in the match ahead of the GBR vs. Alinghi contest - OneWorld and Stars & Stripes - were both flying protest flags before their match was abandoned for breaching the leg time limit.

The GBR Challenge Request will be heard by the International Jury on Thursday. Also pushed back was the protest hearing between Oracle BMW Racing and Team Dennis Conner from Tuesday's non-race.
