SAN DIEGO (AP) -- America's Cup challenger BMW Oracle Racing has confirmed that BOR 90, the giant trimaran being tested in San Diego, is the boat it will use in its showdown against defending champion Alinghi of Switzerland in February.

The Americans made the disclosure in New York State Supreme Court on Monday in an ongoing legal tussle between the bitter rivals.

Justice Shirley Kornreich didn't rule on when the Americans must submit a Custom House Registry, which the Swiss want in order to confirm that the 90-foot trimaran matches the dimensions listed in BMW Oracle Racing's challenge document.

There had been speculation that BMW Oracle Racing, owned by software tycoon Larry Ellison, was building a new boat.
