Jumbo container ship

Jumbo container ship is a loose marketing label for the largest box ships, the ultra-large container vessels (ULCVs) of roughly 14,000 TEU and up. It carries no precise definition; the trade uses the established tiers instead: feeder, feedermax, Panamax, post-Panamax, Neopanamax (up to about 14,000 TEU and Neopanamax-lock compatible), and ULCV above that. Ships in the jumbo bracket, such as the 23,992 TEU Ever Ace or the 18,270 TEU Maersk Mc-Kinney Moller, exceed 400 m length overall and 59 m beam, too wide for the Panama Canal, and run fixed Asia-Europe loops through the Suez Canal. Use ULCV or the specific TEU class in technical work; jumbo is a media term, not a class.
