Post Panamax Vessel

What is a Post Panamax vessel?

A Post Panamax vessel is a ship that is too large to pass through the original locks of the Panama Canal. These ships were developed to accommodate growing global trade volumes and are commonly used for transporting bulk cargo and containers. Post Panamax vessels are larger than Panamax ships, but smaller than the newer Neopanamax and Super Post Panamax vessels, offering greater cargo capacity for efficient international shipping.

How Big is a Post Panamax Ship?

Post Panamax ships exceed the size limits of the original Panama Canal. They are typically up to 366 meters (1,200 feet) long, with a beam (width) of 43 meters (141 feet) and a draft (the depth below the waterline) of around 14.5 meters (48 feet).

How Many Containers (TEU) can a Post Panamax Vessel Carry?

A Post Panamax vessel can carry between 5,000 and 10,000 TEUs (Twenty-foot Equivalent Units), depending on its specific size and design. This capacity makes them ideal for transporting large volumes of goods, such as consumer products and raw materials, across major shipping routes.

How Many Cargo Holds Does a Post Panamax Ship Have?

Post Panamax vessels typically have between 8 to 12 cargo holds, depending on their design and purpose. These holds are used to store a combination of containers and bulk cargo, optimizing space and ensuring efficient loading and unloading at ports. The multiple cargo holds allow for better weight distribution and cargo management during voyages.

What is a Super Post Panamax Vessel?

A Super Post Panamax vessel is an even larger ship than the standard Post Panamax. These ships are often over 366 meters (1,200 feet) long and can carry more than 10,000 TEUs. Super Post Panamax vessels are used on major trade routes where large volumes of goods need to be transported, particularly between Asia, Europe, and North America.
