The Duke and Duchess of Cambridge set sail on a catamaran to watch and cheer on the victorious team of the Portsmouth leg of the America's Cup World Series.
Despite rough seas and high-speed winds, Kate and Will, who are both keen sailors, braved the weather and hopped on a boat to watch the Cup up close.
Sporting the Olympic champion's team shirts, the royal couple cheered as Sir Ben Ainslie’s team sailed to victory in Hants.
The Duchess, 34, arrived in a Land Rover wearing casual black jeans and nude wedges.
With her brunette locks going wild in the wind, Kate soon gave up fighting the breeze and tied her shiny hair into a relaxed ponytail before hopping on board.
Will and Kate couldn’t contain their delight for the winning team as they returned back to the event village and presented the winning awards to Sir Ben and his team.
After the pair left the stage, the winners celebrated in style by spraying champagne in front of thousands of spectators.
