He's been described as England's best sailor since Sir Francis Drake (played bowls, beat the Spanish Armada) and over the next month, Sir Ben Ainslie can add to his already impressive sailing CV.
Ainslie's laid-back demeanour off the water gives way to a burning competitive streak once he leaves shore, but before he can lift the America's Cup off New Zealand, he must first overcome a former ally with whom he already shares unique history in the regatta.

- Since 1992, every boat Ainslie sails has been named Rita, after his mother bought a badge during a visit to St Rita's Church at Tenerife and sewed it into her son's lifejacket for good luck. His current AC75 is called Britannia, which contains the name 'Rita'.

- Married to Sky Sports News presenter Georgie Thompson, whom he met at a 2011 corporate event. "Ben was at the same table as me, but I didn't take much notice of him, until he got up to do a Q&A on stage. I don't recall what he said, but we shared a look and I thought, 'Here we go'."
- The pair have a daughter Bellatrix and dog Biggles.
- Became Spithill's right-hand man during the 2013 America’s Cup series against Team NZ and played a major role in turning around an 8-1 deficit to defend the 'Auld Mug'. The pair will face each other in this month's Prada Cup challenger final.
