Challenge XII (KA-10)

Built in 1982 according to the International Third Rule.


Built in 1982 according to the International Third Rule as challenger for the 1983 America’s Cup, her design was a point of departure with traditional lines but having a narrower beam and small bulge below waterline.

1983: KA-10 was sold to the Royal Yacht Club of Victoria (AU), and sent to Newport for the challenger trails.

1985: Club Nautico Marina di Carrara Consorzio Futurea purchased her intending to use her as Italian challenger for the 1987 America’s Cup, due to financial constraints this did not come to pass.
