The Duchess of Cambridge is now an advanced certified diver and has passed a Professional Association of Diving Instructors (PADI) Advanced Open Water Diver qualification test.

The Duchess, now a mother of two, can keep up with her husband, the Duke of Cambridge, who is an avid diver and the president of the British Sub-Aqua Club.

Kensington Palace confirmed the Duchess’ new qualification to The Telegraph.

With the passing of the test, she’s now qualified to dive 98 ft, or 30 meters. In order to pass it, she had to complete a series of five dives.

“Diving is something the Duchess very much enjoys, and the Duke of Cambridge, who is of course President of the BSAC, has said in the past that he is hopeful his children will become interested in the sport,” said a spokesperson for the Duchess.

The Duke dives at the Middleton family’s vacation home in Mustique, which is where his wife is rumored to have obtained her qualification.

Middleton gave birth to her second child, Princess Charlotte, in May.
