San Francisco has been told it will lose the right to host the next America's Cup unless a deal is signed by Friday.

The warning came in a letter the Golden Gate Yacht Club sent to Mayor Gavin Newsom and other officials.

America's Cup official Stephen Barclay said San Francisco officials recently changed key points in an agreement that had been negotiated between the city and the yacht club and then sent to the Board of Supervisors in early November to begin the approval process. The board's finance committee will hold a final hearing Monday, and the full board is expected to vote on the agreement Tuesday.

"They're holding on by their fingernails at the moment," Barclay told the Associated Press on Saturday from his home in Auckland, New Zealand. "It was theirs to lose and they were told that."
