The Duchess of Cambridge is now an advanced scuba diver.
A Kensington Palace official has confirmed that Kate has built on her enjoyment for scuba diving by passing a Professional Association of Diving Instructors advanced open water diver qualification. It means she can dive to a depth of 30 metres.
Enjoying the waters looks like it could be a family affair as the Duke of Cambridge is also an experienced diver.
William is now the third generation of the monarchy, after his father and grandfather, to head the British Sub-Aqua Club (BSAC).
The Duchess is thought to have gained the qualification from a diving school in Mustique, according to The Telegraph.
There are five dives - including the must-do deep and underwater navigation dives - which have to be completed successfully in order to gain the advanced qualification.
