The World's Top 10 Mega-Yachts

LONDON, June 18, 2009 — -- As the world's largest yacht glided out of Blohm + Voss shipyard in Hamburg, Germany, last week, crowds of onlookers watched the vessel and, perhaps, dreamed of who was onboard the mega-cruiser.

Reports have surfaced that Russian billionaire Roman Abramovich is the proud owner of the 557-foot ship, which Blohm + Voss Industries would not confirm.

"Our company is not allowed to talk about it," a company representative said.

Regardless of the owner, the Eclipse is now in first place on the list of the world's largest yachts. It reportedly features a missile-detection system, two helicopter landing pads, a swimming pool and a submarine that doubles as an escape pod.

It also features an armor-plated master suite, as well as bullet-proof windows to keep its master and commander safe.

According to London's Daily Mail, the Eclipse was designed to overshadow the world's former largest yacht, a 525-foot super-cruiser owned by the Sheikh of Dubai.

Here's a look at the remaining nine of the Top 10 largest yachts in the world.
