Panamax Ship

What is a Panamax Class Ship?

A Panamax-class ship is a vessel that is specifically designed to fit through the original locks of the Panama Canal. These ships must adhere to certain size restrictions, which were established to ensure they can pass through the canal’s locks and accommodate global trade. Panamax vessels are commonly used for transporting goods like grain, coal, and containers across international waters.

What is the Size of a Panamax Vessel?

Panamax ships are built to meet the maximum size allowed for the original Panama Canal locks. These ships have a length of approximately 289.56 meters (950 feet), a beam (width) of 32.31 meters (106 feet), and a draft of about 12.04 meters (39.5 feet). Their cargo capacity is typically around 52,500 deadweight tons (DWT) or 5,000 TEUs.

Neopanamax class vessels are much larger and can navigate the new canal locks opened in 2016.

Capesize vs. Panamax Ships

Capesize ships are larger than Panamax vessels and are too big to pass through the Panama Canal, often requiring longer routes around the Cape of Good Hope or Cape Horn. While Panamax ships are designed for canal passage, Capesize vessels are primarily used for transporting bulk cargo, such as coal and iron ore, on longer oceanic routes. Capesize ships have a larger capacity, often exceeding 150,000 DWT.
