As an accomplished yachtsman and fully fledged member of the Danish Navy's elite special operations forces, Denmark's Crown Prince Frederik clearly thrives on the ocean waves. So when it came to his 40th birthday on Monday, the handsome royal knew exactly how he wanted to mark the special occasion.

With his elegant wife Princess Mary by his side, Frederik headed for a party aboard the Danish royal yacht Dannebrog, which was moored just off Copenhagen.

Built in 1932, the vessel is one of just two such ships remaining in the world - serving as an official royal residence during summer cruises and official visits overseas.

Also joining the group of close friends and family on the yacht was the birthday boy's mother Queen Margrethe. The popular Danish monarch brought a splash of colour to the proceedings in a bright fuchsia and canary yellow outfit.
