America's Cup organizers have given up attempts to convince the New Zealand challengers to allow more sailing than the three races specified by the rules document governing the competition.

The resolution means next month's match between Michael Fay's monohulled sloop and the San Diego Yacht Club's catamaran will be sailed according to the format outlined in the century-old Deed of Gift, challenger officials said.Racing is scheduled to begin Sept. 7 off San Diego.

The deed allows terms and conditions of the competition to be changed by mutual consent. Without such agreement, however, the deed's guidelines take precedence.
