"Panamax" refers to the maximum size of a ship that can pass through the Panama Canal. This canal connects the Atlantic Ocean to the Pacific Ocean and has specific dimensions that limit the size of vessels. The standard Panamax dimensions are approximately 965 feet in length and 106 feet in width, allowing for efficient transit through the canal. The term "Panamax" is significant in maritime trade, as it influences shipping routes and costs. Ships designed to these specifications can carry large quantities of cargo, making them economically viable for international shipping. The introduction of the Neopanamax category has since expanded these dimensions, accommodating larger vessels after the canal's expansion in 2016.
