If the charter party does not specify the loading/unloading time, what can the captain do?

When a charter party does not specify the loading or unloading time, the captain can demand demurrage for additional days. Demurrage is a charge that is incurred when the ship is delayed beyond the agreed laytime for loading or unloading. In situations where there is no specified time, the captain has the right to claim demurrage if the delay is caused by factors outside of their control, such as port congestion or logistical issues.

This option acknowledges the financial implications of extended port stays, emphasizing the captain's role in protecting the ship's interests and the owner's investment. The concept of demurrage is well-established in maritime law, providing a remedy for shipowners against undue delays.

The other options do not align with the typical rights or actions of the captain in such circumstances. Increasing freight charges or seeking compensation from the owner would not be appropriate actions based purely on a lack of specified time. Requesting a schedule adjustment might be logical in some contexts, but it is not directly tied to the standard rights concerning loading and unloading delays as outlined by standard maritime practices.
