 By comparison, a shipment of canoes, which were not packaged for shipment, would be light but would take up a large volume, ensuring the customary freight unit would be the measurement ton of .If a canoe were wide by high by long (0.6 m x 0.6 m x 3 m), its measurement would be 40 cubic feet (2 x 2 x 10) which would be one measurement ton (anything less than 100 would be 1 by default) and hence the limitation would be $500 per canoe.The courts, possibly believing that Congress' approach was too cumbersome, jettisoned the word "customary" from the phrase "customary freight unit" and decided that whatever freight unit the shipowner applied would be the freight unit for determining the limitation on liability.
