Sold for: $168 million

Year: 2006

If we were planking on billions, we would do our auctioning at an accredited auction house, but what do we know? Obviously less than Russian billionaire Roman Abramovich who bought the Frank Mulder-designed 405-foot yacht for a record setting $168,000,000.  The megayacht featured 10 multi-level VIP rooms, eight guest rooms, a movie theater, and a helicopter pad. The auction actually ended at $85,000,000, but that was only the 50% down payment required by Fort Lauderdale’s 4Yacht brokerage firm.
