So ferocious were the celebrations following Australia's victory in the 1983 America's Cup that the then Prime Minister Bob Hawke said bosses who sacked workers for not turning up to work were bums. It's seen as one of the country's greatest sporting triumphs, but now a Dutch naval architect has come forward claiming that he designed the famous winged keel that helped propel Australia II to victory. Peter Van Oossanen said he had grown tired of the Dutch design team being airbrushed out of history and that the record should be corrected. But the businessman Alan Bond, who bankrolled the boat, said the winged keel was 100 per cent Australian and that any other suggestion was codswallop.
