“Time now is money, and a lot of money,” said Panama Canal tug captain Luis Estribi as sunlight danced on the water near the Panama Canal’s Pacific entrance at Ciudad de Panamá.
Estribi was guiding a vessel from China, the Tai Prosperity, through the canal’s Pedro Miguel locks to the Port of New Orleans. The Tai Prosperity, a carrier of bulk commodities such as grain, is classified as a Panamax ship.
Panamax is a worldwide maritime shipping measurement that refers to the maximum-sized vessel that can pass through this canal.
But today, Panamax is passé. Now, it’s all about post-Panamax, vessels that can carry up to three times the cargo as Panamax vessels. But post-Panamax vessels are too wide for the existing Panama Canal.
