World's coolest superyachts. Biggest, most expensive: Azzam. With a price tag of $627 million and a length of 590 feet, Azzam is bigger than a U.S. Navy destroyer. Not much is known about the world's longest and most expensive yacht.

It was officially unveiled for the first time in April following three years at the shipbuilder's docks in Bremen.
