Concept:A general average loss covers a voluntary sacrifice made to save the entire ship and its cargo.
Explanation:When cargo is thrown overboard intentionally to lighten the ship and prevent it from sinking, it is a deliberate act for the common safety of the ship, crew, and remaining cargo.
This type of loss is shared proportionally by all parties whose interests were saved.
The loss is not suffered by the cargo owner alone, so it is not a particular average loss.
It is also a partial loss, not a total or constructive loss.
Hence, the correct classification is general average loss.
