What is the primary authority governing navigation on the high seas?

The primary authority governing navigation on the high seas is international maritime law. This body of law is developed through treaties, conventions, and customary practices recognized by nations globally. It establishes the rights and responsibilities of nations regarding the use of the oceans and includes various regulations such as the United Nations Convention on the Law of the Sea (UNCLOS).

International maritime law ensures that all vessels, regardless of their country of registration, can navigate the high seas freely while adhering to the principles of safety, navigation, and the prevention of pollution. This framework is fundamental in promoting cooperation among nations to maintain safe and orderly maritime navigation, which is essential for international trade and security.

Local authority rules, government regulations, and registered vessel regulations are typically applicable within territorial waters or specific jurisdictions but do not hold the same overarching authority on the high seas, where international agreements take precedence.
