AUCKLAND, New Zealand (AP) _ Team New Zealand's America's Cup defender and Italian challenger Prada will unveil their keels Tuesday in the buildup for the best-of-9 series.

Team New Zealand will use the new boat NZL60, the latest Black Magic. The keel and underwater appendages of the defender will be briefly open to the public at the team's base.

Prada edged AmericaOne 5-4 in the challenger series final to advance to the America's Cup.

The competition begins Saturday.
