Question 45 GLI02 - Mate of Unlimited Tonnage

The Correct Answer is B **Explanation for B (One prolonged blast):** The situation described – a vessel nearing a bend or an area where other vessels may be obscured (such as leaving a berth or anchorage) – falls under the requirements for maneuvering and warning signals outlined in both the International Regulations for Preventing Collisions at Sea (COLREGs, Rule 34) and the Inland Navigation Rules. Rule 34(e) specifically addresses this scenario: "A vessel nearing a bend or an area of a channel or fairway where other vessels may be obscured by an intervening obstruction shall sound **one prolonged blast**." This signal is a warning intended to alert any vessels on the other side of the obstruction to the presence of the approaching vessel. **Why other options are incorrect:** * **A) One short blast:** This signal indicates "I intend to leave you on my port side" when maneuvering in sight of another vessel. It is a specific maneuvering intention signal, not a blind warning signal for bends. * **C) Two short blasts:** This signal indicates "I intend to leave you on my starboard side" when maneuvering in sight of another vessel. Like one short blast, it is a specific maneuver intention signal. * **D) One long blast:** While "prolonged" and "long" are often used interchangeably in common speech, in the context of sound signals defined by the Rules (Rule 32), a "prolonged blast" is a blast of from four to six seconds duration. The term "long blast" is not the precise regulatory term for the required signal in this situation. The required signal for a blind bend is precisely **one prolonged blast**.
