What is a key component of the Peace of the Port doctrine?

The Peace of the Port doctrine emphasizes that foreign states maintain sovereignty over their flagged vessels, allowing them to control operations while in port. This principle acknowledges the rights of other nations concerning their shipping activities and promotes international maritime relations by preventing unilateral actions from host nations against foreign vessels.

Effective enforcement of maritime law is achieved through mutual respect for jurisdictional boundaries. By recognizing that foreign-flagged ships are subject to the laws of their flag states, the doctrine helps maintain order at sea and in port facilities while balancing the enforcement power of local authorities with the operational autonomy of foreign vessels.

Thus, the key component aligns with the idea that the state whose flag a vessel flies has the primary authority to regulate activities aboard that ship, a fundamental aspect of maritime law reflecting the interconnectedness and respect among sovereign nations in global shipping practices.
