Kamsarmax
A dry-bulk carrier of about 80,000–85,000 DWT, sized to the maximum length that can load at the port of Kamsar in Guinea.
Kamsarmax describes a Panamax-type bulk carrier of roughly 80,000 to 85,000 deadweight tonnes, with the key constraint being an overall length of about 229 metres — the maximum that can berth at the bauxite port of Kamsar in Guinea.
It sits just above the classic Panamax in the dry-bulk size ladder and is one of the most actively traded bulker classes, carrying grain, coal and bauxite on the major trades.
