Question 42 UFV01 - Master - Uninspected Fishing Vessels

The Correct Answer is C ### Why Option C is Correct **Option 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 Annex III, which details sound signaling appliances. For vessels less than 12 meters in length (which includes a vessel 10 meters in length), Rule 33(1) states that sound signaling equipment is required, but it does not mandate specific mechanical appliances like whistles or bells. Instead, the requirement is flexible: the vessel must be able to make an **efficient sound signal**. A 10-meter vessel must carry **some means of making an efficient sound signal**. This could be a horn, a compressed air canister, or even a mouth-operated whistle, provided it is capable of producing the necessary signals (e.g., one short blast, two long blasts, etc.) clearly and effectively. ### Why the Other Options are Incorrect **A) A bell only:** This is incorrect. A bell is only required for vessels 12 meters or more in length (and usually specifically for vessels 20 meters or more). It is not the *minimum* requirement for a 10-meter vessel, nor does a bell alone constitute the required equipment for collision avoidance signaling. **B) A whistle only:** This is incorrect. While a whistle is the primary means of making maneuvering and warning signals (as required by COLREGs Rules 34 and 35), it is only explicitly required for vessels 12 meters or more in length. For a 10-meter vessel, an *efficient sound signal* can be made by other means, meaning a dedicated mechanical whistle is not the absolute minimum requirement. **D) A bell and a whistle:** This is incorrect. This combination is generally the requirement for larger vessels (typically 20 meters or more). It significantly exceeds the minimum requirement for a small, 10-meter vessel.
