Question 66 GLI01 - Master-Unlimited Tonnage

The Correct Answer is D **Explanation for Option D (It must be carried on board):** Option D is correct because U.S. federal regulations governing documented vessels explicitly require that the Certificate of Documentation (or a valid temporary certificate) must be carried on board the vessel at all times. Specifically, 46 U.S.C. § 12110(c) and related regulations emphasize that the certificate must be available for examination upon demand by a proper government official (such as a Coast Guard officer, Customs officer, or authorized state official). Failure to have the original or a valid temporary certificate on board constitutes a violation. **Why other options are incorrect:** * **A) It may be retained by the owner at the home port OR kept on the vessel:** This is incorrect. The regulations mandate that the certificate must be kept **on the vessel**, not held separately at the owner's home or office (the "home port" office). * **B) It must be posted under transparent material in the pilothouse:** While it is common practice and recommended for ease of access (especially for commercial vessels), the law does not strictly require that it be "posted under transparent material" or specifically located in the pilothouse. The requirement is simply that it must be aboard and available. * **C) It must be kept on file at the corporate offices of the owner or operator:** This is incorrect. While copies may be kept on file for administrative purposes, the **original** Certificate of Documentation must travel with the vessel itself.
