Question 69 GLI04 - Mate of LT 500-1600 GRT

The Correct Answer is A **Explanation for Option A (Correct):** The requirement for licensed mariners, including the Operator of an Uninspected Passenger Vessel (OUPV/Six-Pack license holder), to produce their Merchant Mariner Credential (MMC) is established in 46 CFR § 10.211(a) (formerly 46 CFR § 10.209(a)). This regulation mandates that any licensed or documented mariner must produce their credential to any Coast Guard officer for inspection immediately upon demand. This is a fundamental requirement for exercising the privileges of the license and ensures that the mariner is properly credentialed while operating the vessel. **Explanation for Option B (Incorrect):** While the OUPV license specifically allows operation of vessels carrying not more than six passengers for hire, the requirement to produce the MMC is not contingent upon the number of passengers aboard. The operator must produce the credential regardless of the vessel's current loadout or specific operating status, simply by virtue of holding the credential and operating a vessel under its authority. **Explanation for Option C (Incorrect):** Although a mariner would certainly be required to produce their MMC following a marine accident as part of the investigation process, this is not the *only* time. The requirement is an "upon demand" requirement by a USCG boarding officer at any time the vessel is being boarded or inspected, not just during an emergency or investigation. **Explanation for Option D (Incorrect):** This option is factually incorrect. The Operator of an Uninspected Passenger Vessel (OUPV) license *is* a Merchant Mariner Credential (MMC), and the operator is required by federal regulation (46 CFR § 10.211) to have it accessible and produce it upon request.
