Former Penryn Junior School pupil, Olympic sailor Sir Ben Ainslie was joined by the Duchess of Cambridge as he launched Britain's bid to win the historic America's Cup yacht race.
In the shadow of the National Maritime Museum in Greenwich, south east London, Sir Ben told Kate about the plans to win the coveted trophy.
The former Penryn Junior School pupil will skipper the team that aims to triumph in the 35th America's Cup being staged in 2017, with the entry made through the Royal Yacht Squadron club.
The Royal Yacht Squadron club hosted the first race which took place off the Isle of Wight in the mid-19th century - but a British team has never won it.
The Olympic sailor said: "We want to bring it home, it would be an amazing thing for this country."
Kate, who wore a Jaeger dress, is a keen sailor who watched some of the London 2012 Olympic racing on the Isle of Wight.
