What type of vessel requires a Certificate of Documentation?

A Certificate of Documentation is required for vessels that are operated under the authority of the United States. This certificate serves as proof of U.S. nationality and is often necessary for vessels that participate in international trade or that operate in navigable waters.

In the maritime context, vessels that are documented provide certain legal advantages, including the ability to engage in coastwise trade, which is a trade route between points in the same country. Additionally, having a Certificate of Documentation is essential for compliance with specific regulations that apply to commercial vessels, particularly for those that might engage in trade or transportation on a larger scale.

The other options describe scenarios that do not necessitate a Certificate of Documentation. For instance, vessels exclusively used in inland waters typically do not require documentation; they usually operate under state registration rather than federal documentation. Similarly, the operations of privately-owned vessels or those that do not engage in commercial activities generally fall outside the requirements for a Certificate of Documentation, as these vessels may be registered differently and do not have the same legal obligations regarding trade and navigation.
