What does the term LASH refer to in shipping?

The term LASH, which stands for Lighter Aboard Ships, specifically refers to a type of shipping system used for transporting cargo. In this system, lighters—small, flat-bottom vessels—are loaded with cargo and then lifted onto a larger ocean-going vessel. This allows the larger vessel to transport the lighters, which can be unloaded at ports that may not have the facilities to accommodate the larger ships.

Using the LASH system enables more flexibility and efficiency in cargo handling, especially in ports that are shallow or not equipped to handle large ships directly. This innovation in shipping logistics allows for streamlined operations, reducing congestion at ports and increasing the speed at which cargo can be delivered to its final destination.

The other choices do not accurately reflect the term's definition or its application in maritime operations, which is why those options do not represent the correct answer.
