Credentials & Routes Practice Questions

1. What does the OUPV (Operator of Uninspected Passenger Vessels) credential authorize?

• A.Operating an uninspected vessel carrying no more than six passengers, at least one of whom is carried for hire✓
• B.Operating any inspected small passenger vessel up to 100 gross tons
• C.Operating a vessel carrying up to twelve passengers on near-coastal routes
• D.Operating a towing vessel of unlimited horsepower

Why: The OUPV — commonly called the 'six-pack' — lets the holder carry up to six passengers (with at least one for hire) on an uninspected vessel. Carrying seven or more passengers, or operating an inspected vessel, requires a Master's license and a vessel with a Certificate of Inspection.

2. A vessel certificated under Subchapter T is best described as a:

• A.Small passenger vessel of under 100 gross tons carrying more than six passengers✓
• B.Towing vessel of 26 feet or more in length
• C.Uninspected fishing vessel
• D.Passenger vessel of more than 100 gross tons

Why: Subchapter T covers small passenger vessels under 100 GT that carry more than six passengers (or carry at least one passenger for hire and meet other size/route triggers). These are inspected vessels requiring a Certificate of Inspection — beyond the scope of an OUPV.

3. A Master 100 Gross Tons (Near Coastal) credential authorizes a mariner to:

• A.Carry no more than six passengers regardless of vessel size
• B.Operate any vessel of unlimited tonnage on oceans
• C.Operate inspected passenger vessels up to 100 GRT carrying more than six passengers, per the vessel's Certificate of Inspection✓
• D.Operate only sailing vessels

Why: A 100-ton Master may operate inspected vessels up to 100 GRT and carry passengers up to the number authorized by the vessel's Certificate of Inspection — far more than the OUPV's six. The exact passenger limit, route, and waters are stated on the COI.

4. How often must a Merchant Mariner Credential officer endorsement normally be renewed?

• A.Every year
• B.Every 3 years
• C.Every 5 years✓
• D.It never expires

Why: MMC officer endorsements are valid for five years and must be renewed, which includes meeting recency-of-service or open-book exam requirements, a current physical, and drug-test compliance.

5. A mariner holding an OUPV who wants to legally carry twelve passengers for hire on an inland tour boat must obtain:

• A.Nothing more — the OUPV already allows it
• B.A Master's license appropriate to the tonnage and operate a vessel holding a valid COI for that number of passengers✓
• C.Only a radar endorsement
• D.A second OUPV credential

Why: Carrying more than six passengers means the vessel must be inspected (COI) and the operator must hold a Master's license of suitable tonnage and route. The OUPV alone never authorizes carrying seven or more passengers.
