It used to belong to Prince Bernhard of Holland who recently passed away. I don´t know for how long the yacht has been on the market, but a couple of years ago she had a fire in the dining room and got an extensive refit at Moonen. http://www.moonen.com/refit/jumbo/main.html
The Jumbo VI is back at Moonen's. 4 grandchildren of Prince Bernard, brought her back from Porto Ercole in Italy. The Jumbo is now for sale for 2.6 million euro
This yacht has been renamed "Libertas" i saw her in Antibes at the beginning of the summer. Our Captain spoke 2 the captain of Libertas for some time actually, discussing the history of the yacht. I will try to find a few photographs!
