Question 48 GLI08 - Limited OUPV

The Correct Answer is C ### Explanation for Option C ("Being towed") The whistle signal described—one prolonged blast followed by two short blasts (• — • •)—is the required sound signal for a **vessel restricted in her ability to maneuver (Rule 35(c))** when making way through the water in or near an area of restricted visibility. A vessel or object **being towed** (Rule 35(h)) is required to sound a signal of **four short blasts** (indicating the presence of the tow) immediately after the towing vessel's signal (which is usually one prolonged and two short blasts, but only if the towing vessel is also restricted in its ability to maneuver—otherwise, the towing vessel sounds only one prolonged blast, Rule 35(a)). Therefore, a vessel **being towed** (Option C) does **not** sound the signal of one prolonged blast followed by two short blasts, making it the correct exception. --- ### Explanation of Incorrect Options **A) Fishing with trawls (Incorrect)**: A vessel engaged in fishing with trawls is defined as a **vessel restricted in her ability to maneuver** (Rule 3(g)(v) and 27(c)). As such, when making way in restricted visibility, it is required to sound the signal of one prolonged blast followed by two short blasts (Rule 35(c)). **B) Towing astern (Incorrect)**: A power-driven vessel engaged in towing astern (which severely restricts its maneuverability) is classified as a **vessel restricted in her ability to maneuver** (Rule 3(g)(iii) and 27(a)(ii)). When making way in restricted visibility, it is required to sound the signal of one prolonged blast followed by two short blasts (Rule 35(c)). **D) Not under command (Incorrect)**: A vessel not under command (NUC) is inherently restricted in its ability to maneuver and is granted the same rights and responsibilities as a **vessel restricted in her ability to maneuver** (Rule 3(g)(i) and 27(a)(i)). When making way in restricted visibility, it is required to sound the signal of one prolonged blast followed by two short blasts (Rule 35(c)).
