A clause in the charter party requires a vessel's owner to pay dispatch money when the vessel __________.

Correct Answer: Option D — loads and discharges its cargo in less time than specified

Dispatch money is a contractual incentive paid by the shipowner to the charterer. It is earned when the charterer completes the loading or discharging operations in less time than the 'lay days' allowed in the charter party, effectively rewarding the charterer for the vessel's earlier-than-expected departure.
