Question 42 FCP01 - First Class Pilot

The Correct Answer is C ### Why Option C is Correct: **C) Any means of making an efficient sound signal** is correct because it directly reflects the requirements of the International Regulations for Preventing Collisions at Sea (COLREGs) Rule 33(a) and (b), concerning vessels of this size. * **COLREGs Rule 33 (Equipment for Sound Signals)** states that a vessel of less than 12 meters in length is **not required** to be fitted with the specific equipment (whistle and bell) mandated for larger vessels. * Instead, Rule 33(a) requires such a vessel to be provided with **"some other means of making an efficient sound signal."** This "efficient sound signal" must be audible and capable of producing the regulated short and prolonged blasts (Rule 32). This could be a portable air horn, a mechanical horn, or another device, provided it meets the audibility standards. ### Why Other Options Are Incorrect: **A) A bell only:** Incorrect. Vessels under 12 meters are not required to carry a bell. A bell, while useful for anchorage signals, cannot efficiently produce the maneuvering and warning blasts (short and prolonged) required by COLREGs Rule 34. **B) A whistle only:** Incorrect. While a whistle would be effective, it is not the *minimum requirement*. The minimum requirement allows for "any means" (such as a foghorn or air horn) that is efficient, not specifically a permanently mounted mechanical or electric whistle. **D) A bell and a whistle:** Incorrect. This requirement applies to vessels of 12 meters or more in length. Vessels under 12 meters have the simpler, less restrictive requirement of only needing an "efficient sound signal."
