Our Aquatic Correspondent Jeff Davis has been keeping tabs on the launch of the Emma Maersk, the largest container ship in the world, over at his most excellent blog. Jeff writes:

After months of speculation overseas about her alleged dimensions and capacity, $38 billion, Denmark-based Maersk Line—the Microsoft of the shipping industry—has officially launched the Emma Maersk, now the largest container ship on the planet. How large? For starters, she's a quarter-mile bow to stern (1,303 ft.), longer than the Saratoga or any aircraft carrier. The ship also reportedly carries the largest diesel engines ever manufactured.
