Question 45 RVR05 - Master of LT 100 GRT

The Correct Answer is A. **Explanation for A (Correct Answer):** Option A ("Three strokes on the bell before and after the anchor signal") is correct according to the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 35(g). This rule applies to both International and Inland waters (as Inland Rules generally align with or adopt this specific provision). Rule 35(g) specifies that a vessel aground in restricted visibility (like fog) must give the bell signal (rapid ringing for about 5 seconds at intervals of not more than 2 minutes) *and* immediately before and after the rapid ringing of the bell, it shall strike the bell three separate strokes. This distinctive three-stroke signal serves to indicate the vessel's disabled status (aground) and location to approaching vessels. **Explanation of Why Other Options are Incorrect:** * **B) Three strokes on the gong before and after sounding the anchor signal:** The required signal involves the **bell**, not the gong, for the primary anchoring location (the forward part of the vessel). While vessels over 100 meters use both bell and gong for the anchor signal, the specific three-stroke distress/aground warning mandated by Rule 35(g) is struck on the **bell**. * **C) Four short blasts on the whistle:** Four short blasts is the whistle signal designated for a vessel engaged in pilotage duty (Rule 35(i)), not for a vessel aground. * **D) One prolonged and one short blast on the whistle:** This is not a required signal for a vessel aground in fog. Rule 35 specifies bell/gong signals for anchored vessels and specific whistle signals for maneuvering, towing, or pilotage, but not this combination for an aground warning. The aground status is primarily communicated using the three distinct bell strokes before and after the rapid ringing.
