"In fact, the Dutch Royal House is a rather modern monarchy, which allows commoners to marry into the royal family, and it was the first royal family in Europe to allow girls to succeed to the throne."
Willem-Alexander also chairs a United Nations Panel on water and sanitation in the Third World and he's known for his unconventional approach to issues.
Last September he spoke openly about the lack of access to clean water and proper sanitation that many people in the world suffer from.
"It genuinely upsets me that young children and women living in slums still have to relieve themselves in stinking gutters in the street every day. We cannot accept this," the prince said in his speech.
The Oranje Prince, as he's also called, works for the International Olympic Committee as well.
He is a huge sports fan who has run the New York marathon and taken part in the "Eleven Cities Ice-Skating" event in Holland.
He performed his military service in the Royal Netherlands Navy. He loves flying airplanes and is licensed to fly jets.
The prince reportedly was hoping to take his family there for vacations and to enjoy the privacy the remote coastal place offers, but the Dutch parliament has yet to approve his plan because of security concerns.
Queen Beatrix used to take her family to her summer home in Italy and to Austria for a skiing holiday in wintertime.
The Dutch parliament is expected to argue that it will cost the taxpayer millions to maintain a permanent security level in Mozambique by anchoring a navy ship off the coast close to the prince's proposed vacation retreat.
The issue has still not been resolved and it makes some people wonder if the prince is in fact fully prepared to take over from his mom.
"I bet you that Queen Beatrix will hand over business to her oldest son at the latest when she celebrates her 30th anniversary in 2010," says van der Linden.
But a spokesperson for the Royal House told ABC News, "The only person who knows when she will step down is her majesty, the queen. And she's not telling anyone of her plans yet."
