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 carry a significant amount of cargo while still being able to navigate the canal's locks. These vessels are primarily used for transporting bulk goods, such as grains, coal, and containers. The term "Panamax" refers to the maximum size that can pass through the canal, making these ships essential for international trade routes connecting the Atlantic and Pacific Oceans.
