The 6-year-old royal was spotted sporting an adorable captain’s hat and a wide, toothless grin, as several of his front teeth were absent. He was joined by his younger sister, Princess Charlotte, who rocked a life vest and a sweet smile of her own.
The charity boat race was originally set to take place on Friday but was rescheduled to Thursday due to inclement weather.
Both William and Kate appeared to be in great spirits for the sporty outdoor event, showing off some new tans. Kate wore navy shorts with a cream zip-up jacket and blue baseball cap over her wavy ponytail. Prince William donned the same hat with a black zip-up jacket on the high seas.
For the event, the Duke and Duchess of Cambridge each served as skippers on individual sailing boats in an eight-boat regatta. Each boat represented one of the charities being supported by the Duke and Duchess. William’s four charities were Child Bereavement UK, Centrepoint, London’s Air Ambulance Charity and Tusk, while Kate’s were Action to Addiction, Place2Be, the Anna Freud National Centre for Children and Families and The Royal Foundation.
Several races will take place throughout the day before the King’s Cup winner is named. In the first race, William's boat came in third out of eight and Kate’s came in seventh. In the second race, Kate’s boat was disqualified. Neither William's nor Kate's boats won the King's Cup, with the boat representing Tusk helmed by celebrity outdoorsman Bear Grylls coming in first.
