Adding weight high in a ship can raise its centre of gravity. Carrying too much cargo can place additional demands on its stability, while insufficient ballast may reduce its ability to recover from a significant tilt. If heavy vehicles or cargo containers are not properly secured, they can shift when the vessel turns, creating an additional imbalance.
Investigators concluded that the Sewol’s condition and loading made it vulnerable. During the voyage, a sharp turn caused the ship to lean heavily. Cargo shifted, further undermining its stability. Water entered the vessel, and the growing flooding made recovery increasingly difficult.
The disaster illustrates why loading procedures are a fundamental part of maritime safety. Cargo limits are not simply commercial guidelines. They are tied to the vessel’s ability to operate within safe conditions. Securing cargo is equally important because even a ship that initially remains stable can become dangerous if heavy loads move unexpectedly.
