Question 45 GLI07 - OUPV

The Correct Answer is B **Why option B ("One prolonged blast") is correct:** According to both the International Regulations for Preventing Collisions at Sea (COLREGs Rule 34(e)) and the U.S. Inland Navigation Rules (Rule 34(h)), a vessel nearing a bend or an area where other vessels may be obscured by the bend is required to sound a signal. This signal is **one prolonged blast** (a blast of 4 to 6 seconds). This signal serves as a warning or cautionary measure, indicating the vessel's presence to any approaching traffic that may not yet be visible. **Why the other options are incorrect:** * **A) One short blast:** A short blast (about 1 second) is typically used in maneuvering situations to indicate intent when vessels are in sight of one another, such as "I intend to leave you on my port side" (used in Inland Waters) or "I am altering my course to starboard" (used in International Waters). It is not the signal prescribed for blind bends. * **C) Two short blasts:** Two short blasts are used in maneuvering situations to indicate specific intentions, such as "I intend to leave you on my starboard side" (Inland) or "I am altering my course to port" (International). This is not the signal for approaching a bend. * **D) One long blast:** While the term "long blast" is sometimes used colloquially, the standard regulatory term is "prolonged blast." Regardless, the term "long blast" does not represent a specific regulatory maneuvering or warning signal distinct from the prolonged blast required for reduced visibility or general warning situations (like approaching a bend or departing a dock). However, for the purpose of maneuvering signals, the one prolonged blast (4-6 seconds) is the standardized required signal for an obscured bend.
