Question 42 GLI05 - Master or Mate of LT 200 GRT

The Correct Answer is C ### Why Option C ("Any means of making an efficient sound signal") is correct: The equipment requirements for sound signals are dictated by the International Regulations for Preventing Collisions at Sea (COLREGs), specifically Annex III, which addresses sound signal appliances. For a vessel less than 12 meters in length (such as a vessel 10 meters in length), Rule 33(1) of COLREGs requires that it is **not obliged** to carry the full set of specified sound signaling appliances (a whistle and a bell). Instead, Rule 33(1) states: "Any vessel less than 12 meters in length shall not be obliged to carry the sound signaling appliances prescribed in paragraph (a) of this Rule, but if she does not, she shall be provided with **some other means of making an efficient sound signal**." Therefore, the minimum requirement for a 10-meter vessel is to have **any means of making an efficient sound signal** (e.g., a handheld horn, whistle, etc.). ### Why the other options are incorrect: * **A) A bell only:** This is incorrect because a 10-meter vessel is not required to carry a bell, and a bell alone is generally used for specific signals (like anchoring or restricted visibility) but may not be the primary "efficient sound signal" needed for maneuvering or warning, especially if hand-operated. It is not the *minimum* required equipment defined by the rule. * **B) A whistle only:** This is incorrect for the same reason as A. While a whistle is efficient, the rule specifically exempts vessels under 12 meters from the obligation to carry a mandated whistle, provided they have *any* efficient means. Making a whistle mandatory would contradict the flexibility granted by Rule 33(1). * **D) A bell and a whistle:** This is incorrect because the requirement for both a bell and a whistle only applies mandatorily to vessels 12 meters or more in length (whistle) and 50 meters or more in length (bell). The 10-meter vessel is specifically exempted from needing both of these items.
