What is the basis for the Coast Guard's overall authority?

The Coast Guard's overall authority is derived from Title 14 of the United States Code (USC), which outlines the general powers and responsibilities of the Coast Guard. This title establishes the Coast Guard as a branch of the U.S. Armed Forces and grants it broad powers to enforce laws, conduct maritime safety operations, protect the marine environment, and execute various other functions relevant to national security and public safety at sea.

Additionally, Title 14 provides the necessary legal framework for the Coast Guard to perform its duties effectively, including search and rescue missions, icebreaking operations, and law enforcement activities such as port state control. Understanding Title 14 is essential for recognizing the scope of the Coast Guard's jurisdiction and its role in ensuring maritime safety and security.

The other titles referenced do contain important regulations and provisions related to various aspects of maritime law, but they do not serve as the foundational basis for the Coast Guard's overall authority. Title 33 deals primarily with navigation and navigable waters, Title 46 focuses on shipping, and Title 49 pertains to transportation in general, which do not encompass the full breadth of the Coast Guard's powers and responsibilities as defined in Title 14.
