Question 43

The Correct Answer is A **Explanation of Option A (Correct):** Option A is correct because both the International Regulations (COLREG Rule 33) and the Inland Rules mandate that for vessels required to carry a bell or gong, the equipment must be maintained in good working order, and the sound signals must always be capable of being sounded manually. While automatic sounding devices (such as those for the fog signal whistle) are permitted, the ability to manually operate the bell and gong remains a fundamental requirement for immediate and responsive signaling. **Why the Other Options are Incorrect:** * **B) A vessel of less than 12 meters in length need not have any sound signaling equipment.** This is incorrect. While vessels under 12 meters may not be required to carry the specific whistle, bell, and gong combination of larger vessels, Rule 33 requires that they must be provided with "some means of making an efficient sound signal." They cannot operate without any signaling capability. * **C) Any vessel over 12 meters in length must be provided with a gong.** This is incorrect. The requirement for a **gong** only applies to vessels of **100 meters or more** in length (Rule 33(b)). Vessels between 12 meters and 100 meters are required to have a whistle and a bell, but not a gong. * **D) Automatic sounding of the signals is not permitted.** This is incorrect. Automatic sounding of the prescribed fog signals (whistle signals) is expressly permitted, provided that the equipment is designed so that the manual override is always readily available. Automated timing devices are common, especially on the whistle.
