Question 42 GLI04 - Mate of LT 500-1600 GRT

The Correct Answer is C ### Why Option C ("Any means of making an efficient sound signal") is correct: The equipment requirements for sound signaling are mandated by the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 33(1). COLREGs specifies that vessels less than 12 meters in length are **not** required to carry a whistle or a bell, but they **must** be provided with **some other means** of making an efficient sound signal. A vessel 10 meters in length falls into this category (less than 12m), so the minimum requirement is simply "any means of making an efficient sound signal" (e.g., a compressed air horn, a loud portable foghorn, etc.) that can effectively broadcast the required signals (such as one prolonged blast, five short blasts, etc.). ### Why the other options are incorrect: * **A) A bell only:** This is incorrect. A bell is generally required for vessels 12 meters or more in length in restricted visibility (Rule 33(1)), and for vessels 10 meters in length, it is not the minimum requirement. * **B) A whistle only:** This is incorrect. A whistle (or equivalent) is specifically required for vessels 12 meters or more in length (Rule 33(a)). It is not the minimum requirement for a 10-meter vessel. * **D) A bell and a whistle:** This is incorrect. Both a whistle and a bell are required for vessels 12 meters or more in length (and specifically required equipment for vessels 20 meters or more). This greatly exceeds the minimum requirement for a 10-meter vessel.
