General Average (Marine)

Example

“When the cargo ship jettisoned $500,000 worth of containers to prevent sinking, general average was declared and all cargo owners shared the loss proportionally based on their shipment values.”

Memory Tip

Think 'General Average' as 'Generally, we Average the loss' - everyone shares the sacrifice made to save everyone.

Why It Matters

For businesses shipping goods internationally, understanding general average prevents surprise costs that could significantly impact profitability. Even if your cargo wasn't damaged, you may still owe thousands in shared losses from maritime emergencies.

Common Misconception

Many shippers believe they're only responsible for losses to their own cargo, but general average can make them liable for sharing in sacrifices made to save the entire vessel. This can result in unexpected bills even when their own goods arrive safely.

In Practice

A container ship carrying $50 million in total cargo faces engine failure in a storm. The captain jettisons $5 million worth of containers to lighten the ship and reach safety. Under general average, a shipper whose $100,000 cargo was saved must pay their proportional share: ($100,000 ÷ $45 million remaining cargo) × $5 million loss = approximately $11,111, even though their goods weren't damaged.

Etymology

Derived from ancient maritime law, with 'average' coming from Arabic 'avariya' meaning 'damaged goods.' The principle dates back to Rhodian Sea Law around 800 BC and remains fundamental to maritime commerce today.
