He prefers to remain behind the scenes, but this week regatta director Iain Murray imposed himself as the central figure in the 34th America's Cup by taking the fate of the event into his own hands.
Murray, who says he is "saving the teams from themselves", dropped a bombshell on the eve of the opening ceremony, threatening to scuttle the regatta if his alterations to the design rules are not upheld by the international jury on Tuesday.
Whether he follows through with those threats should the Kiwis and Italians succeed in the jury room remains to be seen, but it is evident from this week's posturing that the 55-year-old Australian is prepared to match the outspoken team heads by playing hardball himself.
Highly regarded in the yachting world, his involvement with the America's Cup began in 1983, when he was helmsman for Syd Fischer's challenger Advance.
He then joined Kevin Parry's Kookaburra syndicate for Australia's defence in 1987, in which he famously lodged 37 protests in a cantankerous defence series (four Australian syndicates were vying for the right to represent the Royal Perth Yacht Club to defend the Cup), but was vanquished in the 27th Cup match by Dennis Conner's Stars & Stripes.
