Panamax vessels are large cargo ships designed to fit through the Panama Canal. They have specific dimensions, typically measuring up to 965 feet in length, 106 feet in width, and a draft of about 39.5 feet. This size allows them to transport a significant amount of goods while still being able to navigate the canal's locks. These vessels play a crucial role in global trade, carrying various cargoes such as containers, grains, and bulk materials. The design of Panamax vessels has influenced shipping routes and logistics, making them essential for efficient maritime transportation.
