Question 42 GLI01 - Master-Unlimited Tonnage

The Correct Answer is C ### Why Option C is Correct: **C) Any means of making an efficient sound signal** is correct because it aligns with the requirements of the International Regulations for Preventing Collisions at Sea (COLREGs), Annex III, Section 1(c) (and the corresponding Inland rules). For vessels less than 12 meters in length (which includes a vessel 10 meters in length), the rules state that they are **not required to carry the sound signaling appliances prescribed in Rule 33(1)** (the whistle and the bell). Instead, they "shall be provided with **some other means of making an efficient sound signal**." This means the vessel only needs a device or method capable of producing a signal loud enough and distinct enough to fulfill the maneuvering and warning signal requirements (Rule 34 and 35). This could be a horn, a manual air horn, or even a siren, provided it is efficient. ### Why the Other Options are Incorrect: **A) A bell only:** Incorrect. While a bell is required for larger vessels, it is not the required minimum equipment for a vessel under 12 meters. Furthermore, sound signaling rules (like Rule 34) primarily require a whistle/horn signal for maneuvering. A bell alone would not meet the requirement for making an *efficient* maneuvering or warning signal. **B) A whistle only:** Incorrect. A whistle (or equivalent horn) is the primary piece of equipment for making maneuvering signals, but the rules specifically *exempt* a vessel under 12 meters from the strict requirement of carrying a "whistle" as defined for larger vessels. The requirement is more generally for *any efficient sound signal*. **D) A bell and a whistle:** Incorrect. This combination is required for vessels 12 meters or more, and specifically for vessels 20 meters or more (the bell requirement kicks in at 12m for Inland and 20m for International). A 10-meter vessel is exempt from this full requirement.
