What happens if a vessel is delayed for more than 30 days?

The scenario describes a situation where a vessel is delayed beyond a specific time frame, which directly impacts how freight charges are calculated. When a vessel is delayed for more than 30 days, it is standard practice within maritime commerce to adjust the freight payment structure according to the distance that the vessel actually traveled prior to the delay.

This proportional payment reflects the principle that the shipper should only pay for the service received up to the point of delay. Since the vessel was unable to proceed as expected due to the delay, charging the full freight amount would be viewed as inequitable. This approach allows for a fair adjustment in the freight charges that corresponds with the distance traveled and the services performed by the vessel up until the delay began.

Therefore, the correct answer emphasizes that freight is calculated based on the actual distance traveled, ensuring that the financial obligations align with the level of service provided before the interruption occurred.
