Yachting: America's Cup fuss over sails

After fighting in court for more than two years over the rules, dates and ports, the bitter America's Cup rivals heading for a February showdown in giant multihulls are now tussling over sails.

Challenger BMW Oracle Racing has questioned whether defending champion Alinghi of Switzerland plan to use sails built in Nevada, in the United States, in what the Americans say is a violation of the 19th-century document governing the event.

The American syndicate claim the cup's Deed of Gift states that a yacht must be constructed in the country of the club it represents.
