Post-Panamax

Post-Panamax refers to ships that are larger than the size limits of the original Panama Canal, which was built to accommodate smaller vessels. These ships cannot pass through the canal without restrictions. As a result, they are typically used on routes that do not require canal transit, such as to or from ports outside the canal's reach. The term highlights the ships’ advanced size, often associated with large container and cargo ships that maximize efficiency for global trade, reflecting how port and canal infrastructure influence the design and operation of maritime vessels.
