Question 42 TV02 - Towing Vessels - Great Lakes and Inland

The Correct Answer is C ### Why Option C is Correct **C) Any means of making an efficient sound signal** is correct because of the requirements outlined in the International Regulations for Preventing Collisions at Sea (COLREGs), specifically Rule 33 (Equipment for Sound Signals). * **Vessels less than 12 meters in length (which includes a 10-meter vessel)** are not required to carry the specific sound signaling equipment (whistle and bell) mandated for larger vessels. * Instead, Rule 33(a) states that vessels less than 12 meters in length "shall not be obliged to carry the sound signaling appliances prescribed in paragraph (a) of this Rule but if they do not, **shall be provided with some other means of making an efficient sound signal**." * An "efficient sound signal" is one that can be heard and understood by other vessels in the vicinity, such as a horn, a compressed air canister horn, or similar device. ### Why Other Options Are Incorrect **A) A bell only:** This is incorrect. A bell is required for vessels 12 meters or more, and a 10-meter vessel is specifically exempted from the requirement to carry a bell (or a whistle) provided it has an alternative efficient means of signaling. **B) A whistle only:** This is incorrect for the same reason as Option A. A whistle is mandatory for vessels 12 meters or more, but not for vessels under 12 meters, provided an alternative efficient sound signal is available. **D) A bell and a whistle:** This is incorrect. This combination is the minimum requirement for vessels 12 meters or more in length, not for vessels 10 meters in length.
