Question 66 ONC02 - Second Mate/Third Mate Unlimited Tonnage

The Correct Answer is A **Explanation of Correct Answer (A):** Option A ("It is required to be marked on the stern with the name of the vessel marked on both bows") is correct because it accurately reflects the U.S. Coast Guard (USCG) regulations for the marking requirements of documented commercial vessels (specifically, the vessel's name and hailing port). According to 46 CFR § 67.121, the **name** of the vessel must be marked on **each side of the bow** (i.e., both bows). The **name** and **hailing port** must be marked on the **stern** of the vessel. **Explanation of Incorrect Options:** * **B) It is required to be marked on both bows and on the keel:** This is incorrect. While the name is required on both bows, neither the name nor the hailing port is required to be marked on the keel (the bottom centerline structure of the boat). * **C) It is not required to be marked anywhere on the vessel:** This is incorrect. Documented vessels are legally required to display their name and hailing port prominently on the exterior of the hull (bows and stern). * **D) It is required to be marked on the keel, stern, and both bows:** This is incorrect. While the stern and both bows are required locations, the keel is not a required location for the name or hailing port.
