Cargo ships will split between practical smaller hulls and larger giants

Are modern cargo ships becoming too large?

Some smaller ships will appear for practical routes and ports, while the largest ships continue growing where economies of scale and profit reward them.

Very large ships lower unit costs on routes and at terminals able to handle them. They also impose practical limits involving port access, cargo flows, scheduling, and resilience. Demand for smaller ships will remain where flexibility matters. At the same time, the commercial logic of scale will continue pushing the largest trades toward still bigger hulls.
