Oracle Team USA skipper Jimmy Spithill is no longer unstoppable in the America's Cup and that's why he's had to change the name of his soon to be published biography.

The Australian helmsman lost the America's Cup last month following a 7-1 defeat to Emirates Team New Zealand in Bermuda.

His biography originally had a working title of Unstoppable - My America's Cup Journey. Heading into the America's Cup regatta last month, the Oracle Team USA skipper held an unbeaten record in the event.

He became the youngest skipper to lift the trophy in 2010 when leading Oracle Team USA to victory over Alinghi before successfully defending the America's Cup three years later, pulling off one of the greatest comebacks ever to bear Team New Zealand 9-8.

But obviously the 'unstoppable' tagline doesn't fit the Spithill narrative now that the Auld Mug is on New Zealand soil.

The book, to be published in August, will now be called Undaunted: A Life in Racing and the Inside Story of My America's Cup.
