After finding her sea legs, the Duchess of Cambridge took a keen interest in the competition, peering through a set of binoculars for a close up, as the competitors navigated the tough course.
After watching the race, windswept Kate headed back to dry land, and chatted to a host of Team GB stars - including gold medal winner Ben Ainslie.
Talking animatedly and sending the team into fits of giggles, the Duchess was reportedly interesting in everything from their medal hopes to training and support staff.
Kate Middleton's latest outing is just one in a long line of Olympic appearances she's put in since the Games began last week.
She has looked unbelievably chic, while at the same time looking "sporty" and like she totally belongs at a track or swim meet. And now, she's taken things a step further -- she's worn a windbreaker to watch the sailing events. And, unsurprisingly, she looked damn good doing it. Kate, obviously, has perfected this art form.
