Question 36 GLI03 - Master-LT 500-1600 GRT

The Correct Answer is A. **Explanation of Option A (Correct Answer):** In the **Inland** Rules of the Road (33 CFR Subchapter E), when a vessel being overtaken agrees to the overtaking vessel's proposal, Rule 34(c) applies. The overtaking vessel's signal (in this scenario, indicating the intention to pass on the starboard side) is **one short blast**. The vessel being overtaken must acknowledge and agree by sounding the same signal: **one short blast**. This signal conveys consent and indicates that the overtaken vessel is ready to take the necessary steps to permit the safe passage of the overtaking vessel. **Explanation of Incorrect Options:** * **B) one prolonged, one short, one prolonged, and one short blast in that order:** This sequence is the distress signal (Rule 37, Annex IV) and has nothing to do with maneuvering or passing agreements. * **C) two prolonged blasts:** A prolonged blast is typically used for a warning signal when approaching a bend or leaving a slip/dock (Rule 34(e)), or as the required whistle signal in restricted visibility (Rule 35). Two prolonged blasts have no designated meaning for signaling agreement to being overtaken. * **D) two prolonged followed by two short blasts:** This signal is the restricted visibility signal for a vessel "not under command," "restricted in her ability to maneuver," "constrained by draft" (International), "sailing vessel," or "fishing vessel," etc., when making way through the water (Rule 35(c)). It is not the signal for agreement to an overtaking maneuver. (Note: The specific signal for agreement under the **International** Rules is one prolonged, one short, one prolonged, and one short blast (B), but this question specifies **INLAND ONLY**, making A correct.)
