Yachting: Speed mystery not solved on day one

Don't expect to know if Team New Zealand or Prada have the faster boat in the first race of the America's Cup on Saturday.

New Zealand skipper Russell Coutts says it won't be obvious in race one: "We might not even know after the series is over."

Have the Kiwis been able to work out how quick Luna Rossa are? "You can't. We race our two boats, we know everything about them, but it's very difficult to get a difference in speed a lot of the time. The wind is too shifty and puffy.

"That's why we have a two-boat programme - otherwise it would be easier to have one boat and do it all on the computer."

Will Team New Zealand win in a clean sweep like '95? "No. If we win 5-0, I will be celebrating for a long, long time. We knew before the Cup started that the conditions here would provide far closer racing."
