Ever Diadem Panama Canal Locks

From Wikipedia: Panamax and New Panamax are terms for the size limits for ships traveling through the Panama Canal. Formally, the limits and requirements are published by the Panama Canal Authority (ACP) titled "Vessel Requirements" and other documents here at Notices to Shipping - Panama Canal.

"Panamax" has been in effect since the opening of the canal in 1914. Ships that do not fall within the Panamax-sizes are called Post Panamax or Super-Panamax. In 2009 the Canal management published the "New Panamax", that will be in effect when the third lane of locks, larger than the current two, are operational in 2014.
