Out on the open seas! Kate Middleton decided to take a break from her royal duties, and instead took some time to do a little bit of sailing!

The Duchess of Cambridge, 37, was spotted on the Isle of Wight on Thursday, August 8, as she and her husband, Prince William, took part in a charity sailing regatta. Other notable faces were among the folks at the event, including professional rower, Helen Glover. Each charity was represented by a different boat in the race, so all were competing for a good cause!

Kate was seen in a white polo shirt, black shorts and a baseball cap, as she clearly went the casual route in hopes of keeping it quite comfortable during the race. The Duke of Cambridge, 37, also had on a similar outfit, as he competed against his wife on a different boat! The royal pair are each a patron of the eight charities that were in play. They included: The Royal Foundation, Child Bereavement UK, the Anna Freud National Centre for Children and Families, Tusk, Action on Addiction, Place2Be, Centrepoint, and London’s Air Ambulance Charity 30th Anniversary Campaign, Tusk.
