What additional indication does a vessel anchored in special anchorage provide regarding fog signals?

1. It is exempt from fog signals

2. It must sound a bell every minute

3. It must use its horn every two minutes

4. It must signal every five minutes

The correct answer is: It must sound a bell every minute

The correct answer highlights that a vessel anchored in special anchorage must sound a bell every minute when visibility is restricted due to fog or poor weather conditions. This requirement comes from the regulations governing the navigation of vessels in fog, which emphasize the importance of sound signals to ensure the safety of all vessels. Special anchorages are designated areas where vessels can anchor safely, often without the typical restrictions that apply elsewhere. However, even in these areas, safety is paramount, especially during fog. The sound signal of a bell provides a reliable auditory cue to nearby vessels, indicating the presence of an anchored vessel, which is especially important in low visibility conditions. This requirement helps prevent collisions and ensures that all vessels are aware of each other's positions when visual signals are compromised. Hence, the necessity of sounding a bell every minute reinforces adherence to maritime safety protocols while in special anchorage areas. Other methods of signaling, like using a horn or specific time intervals for signalling, do not apply in the context of special anchorages as outlined in the regulations.
