PRASLIN, The Seychelles -- Prince William and his new wife Catherine hired a $3.2 million yacht for a treasure islands tour of The Seychelles, The Sun reported Tuesday.

The royal honeymooners spent a day cruising between former pirate hideouts Praslin and La Digue. A source said, "It may be The Seychelles but the area is like something out of 'Pirates of the Caribbean.' There are tropical swamps and the most spectacular wildlife you can imagine."

The plush boat -- named Sea Stream -- costs $42,000 a week to hire, can do top speeds of nearly 40mph and comes equipped with its own jet skis and scuba-diving gear.

The couple dined on sushi, Parma ham and other delicacies during their stay on the 2006 Ferretti motor yacht -- said to be the fastest luxury crewed boat for rent in the paradise island group.

The day out came amid the Duke and Duchess of Cambridge's ten-day honeymoon at a secret island in the Indian Ocean archipelago. They were married in London's Westminster Abbey on April 29.
