Question 42 GLI02 - Mate of Unlimited Tonnage

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), Rule 33, addresses sound signaling equipment. Specifically, for smaller vessels: * **Vessels less than 12 meters in length** are not required to carry a whistle and a bell. * The regulations state that such vessels must carry **some means of making an efficient sound signal**. This allows the operator to choose a device appropriate for the vessel's size (e.g., a handheld air horn, a mechanical horn, or even a portable whistle) that can effectively broadcast the required signals (such as one prolonged blast, two prolonged blasts, etc.). This requirement applies to both international and inland waters (as inland rules typically mirror or simplify COLREGs for smaller vessels). ### Why the Other Options are Incorrect: **A) A bell only** Incorrect. While a bell is required for larger vessels, it is not the *minimum* required piece of equipment for a vessel under 12 meters. Furthermore, a bell alone cannot be used to make required maneuvering or warning signals (which typically require blasts). **B) A whistle only** Incorrect. Although a whistle is required for vessels 12 meters or more, it is not the *minimum* required equipment for a vessel under 12 meters (10 meters in this case). The regulation allows for "any efficient sound signal." **D) A bell and a whistle** Incorrect. This combination is typically required for vessels 20 meters or more in length (whistle and bell). For vessels between 12 and 20 meters, a whistle is required, but a bell is only required if practicable. For a 10-meter vessel, this equipment is excessive and not mandated by regulation.
