Britain's Duchess Catherine has become a qualified scuba diver.
The 33-year-old royal has passed the Professional Association of Diving Instructors (PADI) advanced tests, meaning she can now dive to depths of 98ft, along with her husband Prince William who is head of the British Sub-Aqua Club (BSAC).
A spokesperson for the Duchess told the Telegraph newspaper: "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."
The Duchess - who has two-year-old son Prince George and three-month-old daughter Princess Charlotte - is believed to have successfully gained the qualification while holidaying on the Caribbean island of Mustique earlier this year.
As part of the exam, Catherine would have been made to complete five dives including underwater navigation dives, with photography, fish identification and buoyancy control also being part of the course.
Prince William is the third generation of the monarchy to become head of the BSAC, showing a keen interest in the pursuit.
And the club's chairman Eugene Farrell admitted he was excited Catherine is also a fan of diving.
He said he was, "thrilled that The Duchess of Cambridge shares her husband's interest in the underwater world and has further progressed her diver training."
