Question 36 UFV02 - Mate - Uninspected Fishing Vessels

The Correct Answer is A. **Explanation for Option A (Correct Answer):** In the **Inland** Rules of the Road (33 CFR Subchapter E, Inland Navigational Rules), Rule 34(c) governs signals for agreement to an overtaking maneuver in a narrow channel or fairway. * The overtaking vessel initiates the maneuver by proposing to pass on your starboard side, which requires sounding **one short blast** (Rule 34(c)(i)). * If you, the vessel being overtaken, agree to the maneuver and deem it safe, you must sound the **same signal** as the overtaking vessel to indicate your agreement and understanding (Rule 34(c)(i)). * Therefore, your signal of agreement is **one short blast**. **Explanation for Other Options (Incorrect):** * **B) one prolonged, one short, one prolonged, and one short blast in that order:** This sequence is the general danger signal (Rule 34(d)). If the overtaken vessel disagreed or considered the maneuver unsafe, they would sound five or more short blasts (the danger signal), not this specific sequence. This option is not a standard signal of agreement or disagreement. * **C) two prolonged blasts:** A prolonged blast (4 to 6 seconds) is generally used as a warning signal (e.g., leaving a dock) or in restricted visibility. Two prolonged blasts are specifically used to indicate that a vessel is dead in the water and making no way (Rule 35(b) in restricted visibility) or as part of a meeting or crossing situation in certain contexts, but never as an agreement to an Inland overtaking maneuver. * **D) two prolonged followed by two short blasts:** This sequence is the standard signal required for an overtaking maneuver in **International** Waters (COLREGs Rule 34(c)(i) and (ii)). However, the question specifically states "INLAND ONLY." In Inland Waters, the agreement signal is the repetition of the maneuvering signal (one short blast).
