Sorry Roman. You've been eclipsed.
A new yacht launched Friday by Lurssen, the German luxury boatbuilder, is now the largest motor yacht in the world. Its name is Azzam, and at 590 feet long, it has officially bumped Roman Abramovich's yacht -- the 536-foot Eclipse -- from its number one ranking.
Lurssen won't comment on the ownership. But industry sources say the owner is likely the royal family of Abu Dhabi.

Lurssen will say that the boat was "without the a doubt the most challenging yacht that has ever been built." Aside from its sheer size, Azzam had to be super-fast and able to ply shallow waters "while providing luxurious and sophisticated accommodation to its guests."
For speed, the boat is powered by jets rather than propellers. It's got 94,000 horsepower under the hood. And it hit a top speed of 30 knots, which is about 30 percent faster than most mega-yachts. "It's like a 590-foot jet ski," said one executive involved in the project.

There are no immediate descriptions available of the interior, though we know it's in the hands of French interior designer Christophe Leoni, who's using a "turn of the century Empire style." Nor do we have critical details on the number of Jacuzzis, rotating beds or helicopter pads. But the main salon, at 95 feet long by 60 feet wide, has no pillars dividing the space.
So think Napoleon, if he had a megayacht and $600 million to spend. (Read More Below the Video.)
Azzam will go through sea trials later this summer and will officially launch sometime in the fall.
