Today, September 26th is the 40th anniversary of Australia II's win in the America's Cup off Newport, Rhode Island - handing the New York Yacht Club their first ever defeat since the first defence in 1870.

The departure of the Cup from the New York Yacht Club set the most prestigious trophy in sailing, off on a new direction - starting with the first defence outside USA, and one that in Fremantle is reckoned to be the best ever.
