Which type of vessel requires a Certificate of Documentation (COD)?

A Certificate of Documentation (COD) is essential for certain vessels in the United States, particularly for those meeting specific criteria related to ownership and tonnage. The requirement for a COD applies to any vessel that is at least five net tons and is owned by a U.S. citizen. This documentation serves multiple purposes, including conveying the vessel's lawful ownership and registration, enabling it to be documented for various operations, including fishing and trading.

The threshold of five net tons is significant because vessels below this size are typically not regulated under the same documentation requirements. This distinction helps streamline documentation processes for smaller vessels, which often serve specific, localized purposes.

Additionally, the stipulation that the owner must be a U.S. citizen establishes a legal framework focused on ensuring that certain vessels, particularly those engaged in commercial activities, are linked to U.S. interests. This connection supports maritime security and economic policies.

In contrast, the other choices do not align with the criteria outlined for requiring a Certificate of Documentation, as they either misinterpret ownership requirements, focus on size limits, or unnecessarily broaden the documentation necessity beyond the stipulated guidelines.
