With the launch of the gleaming new Azzam, Russian billionaire Roman Abramovich can no longer lay claim to being the owner of the world's largest superyacht.

At 590- feet long, the Azzam is 57-feet longer than Abramovich's mighty Eclipse -- previously the largest yacht on the waves. The hulking superyacht is significantly longer than a football field, larger than the US Navy's Arleigh Burke-class destroyer and more capacious than many popular cruise ships.

Last month, the behemoth eased cautiously out of its shipyard in Bremen, Germany, ushered by a team of powerful tugboats which were dwarfed by its enormous scale. The yacht has been kept under wraps throughout its construction for the past three years.

The identity of the huge boat's owner remains a mystery, but some speculate that it belongs to a powerful Middle Eastern billionaire. Just building the yacht cost a staggering $605 million -- a fee which doesn't even begin to take into account the sky-high costs of its annual upkeep. In his book on the Lady Linda superyacht, author G. Bruce Knecht said that, "operating and maintaining a yacht is at least 10% of what the thing cost." By which estimation, just keeping the Azzam on the water c

ould cost as much as $60 million every year.
