Kate Middleton is officially a professional scuba diver!

Duchess of Cambridge, Kate Middleton, is officially qualified as an advanced scuba driver.

Mother of Prince George and Princess Charlotte, Middleton is busy not only raising her children, but also diving. Telegraph reported that the Duchess was encouraged by her husband, Duke of Cambridge, who was named the president of the British Sub-Aqua Club.

Middleton passed a Professional Association of Diving Instructors (PADI) Advanced Open Water Diver qualification. This means that she can now dive to a depth of 98 feet! According to Telegraph, the qualification is most risky, seeing as if the diver goes any deeper, he or she involves a risk such as nitrogen narcosis, which gives an equivalent sensation to drunkenness.

“We went diving and they went very deep, more than 90ft. Our instructor said Martin and I weren’t qualified to go on the shark dives that they went on. They’re quite the sportsmen," Middleton said.

A spokesman for the Duchess said that “diving is something the Duchess very much enjoys" and that the Duke of Cambridge "has said in the past that he is hopeful his children will become interested in the sport.”

Chairman of the British Sub-Aqua Club, Eugene Farrell, said, "We are thrilled that The Duchess of Cambridge shares her husband’s interest in the underwater world and has further progressed her diver training."

"Last summer while diving with BSAC, The Duke of Cambridge suggested George may also one day follow in his footsteps, so we hope in the future the whole family may share the same passion for scuba diving," Farrell added.

The royal family is actually really competitive. In 2011, the couple participated in a dragon boat race. Middleton also won during New Zealand's America's Cup yachts race last year.

“We are both very competitive. She beats me at tennis and skiing but I am better at the rest," The Duke commented about his wife.
