Question 38 GLI08 - Limited OUPV

The Correct Answer is D. ### Explanation for Option D (one short blast) - Correct This scenario is governed by the Inland Rules (specifically Rule 34 - Maneuvering and Warning Signals) concerning overtaking in a narrow channel where the overtaken vessel must move to facilitate the passage. * **Inland Rule 34(c)(i)** states the specific signals for overtaking. When an operator desires to overtake another vessel on its **starboard side**, the proper signal is **one short blast**. This signal means, "I intend to overtake you on your starboard side." Therefore, the first whistle signal required to initiate the maneuver is one short blast. ### Explanation of Incorrect Options * **A) two prolonged blasts followed by two short blasts:** This signal (the "danger signal") does not exist in the maneuvering signals under Inland Rule 34. A prolonged blast is a warning signal (Rule 35) or a signal used when emerging from a blind bend (Rule 34(e)), but this combination is not the correct overtaking request. (The danger signal is five or more short blasts, which is not the maneuver intended here.) * **B) two short blasts:** Under Inland Rule 34(c)(i), two short blasts means, "I intend to overtake you on your **port side**." Since the vessel wishes to overtake on the starboard side, this signal is incorrect. * **C) two prolonged blasts followed by one short blast:** This is the signal used to request permission to pass when the vessel is approaching a blind bend or exiting a restricted area (Rule 34(e)). It is not the standard signal for requesting to overtake on the starboard side in a narrow channel.
