In the billionaire boat wars, a new record holder is making waves. The Emirati royal family has run the Russians aground with its seaworthy superbeast: The brand-new ship Azzam, at 590 feet, overshadows the Russian billionaire Roman Abramovich's yacht, Eclipse, by 57 feet.

The bigger boat came at a price: According to CNN, just to build the thing cost $605 million. And that doesn't include the cost for upkeep, which can be 10 percent of the boat's price, per year.

The boat is big — much bigger than a football field and larger than some cruise ships. And relatively speaking, it's fast. It is said to reach speeds of up to 30 knots, or about 35 mph, making it one of the fastest superyachts on the seas.

Although no details of what lies inside have been forthcoming, clues could come from the Eclipse yacht, which boasts features that sound like something a James Bond supervillain would own: an armor-plated master suite, two swimming pools, two helipads, a mini submarine, and even its own missile defense system.

The luxe ship, which the website Super Yachts calls "the most challenging and complex yacht ever built," was also built in record time: just three years and a year of engineering. Engineer Mubarak Saad al Ahbabi assembled and directed the team. Lurssen developed Azzam's technical engineering, Nauta Yachts designed the exterior, and Christophe Leoni designed the interior.

"She truly represents another milestone in yachting history," Peter Lurssen told the Daily Mail.
