Question 42 OSV02 - Mate - Offshore Supply Vessels

The Correct Answer is C ### Why Option C is Correct: **C) Any means of making an efficient sound signal** The International Regulations for Preventing Collisions at Sea (COLREGs), which govern both international and inland waters (where adopted), specify the minimum requirements for sound signaling equipment based on the vessel's length: * **Vessels 12 meters or more in length** must be provided with a whistle and a bell. * **Vessels less than 12 meters in length** are not required to carry a whistle and a bell. According to Rule 33(1), such vessels are required to carry **"some efficient means of making a sound signal."** Since the vessel in question is 10 meters in length (less than 12 meters), it only needs "Any means of making an efficient sound signal" (such as a horn, air horn, or even a police whistle, provided it can produce the required signals effectively). ### Why the Other Options Are Incorrect: **A) A bell only:** This is incorrect because vessels under 12 meters are not specifically required to carry a bell. While a bell could be the "efficient means," requiring *only* a bell (and excluding other efficient means) is too restrictive and not the minimum requirement defined by the rule. **B) A whistle only:** This is incorrect. Whistles are mandatory for vessels 12 meters or more. Vessels under 12 meters are not required to carry a whistle, though they may choose to use one as their efficient means. **D) A bell and a whistle:** This is incorrect. The combination of a bell and a whistle is the requirement for vessels **12 meters or more** in length, not for vessels that are 10 meters in length.
