Q

BOTH INTERNATIONAL & INLAND A sailing vessel with the wind abaft the beam is navigating in fog. Which signal is she required to sound?

🔍 Key Concepts

• Navigation Rules – Part D (Sound and Light Signals), Rule 35 – Sound Signals in Restricted Visibility • Difference between sound signals for power-driven vessels and sailing vessels in fog • Meaning of prolonged blast vs short blast and when combinations are used

💭 Think About

• First, recall what sound signal a power-driven vessel making way must sound in fog. Then think: does a sailing vessel use the same signal, or a different pattern? • Look at which options contain only prolonged blasts and which contain short blasts. Ask yourself: in fog, are short blasts normally used to indicate maneuvering intentions, or the type/status of a vessel? • Consider whether a vessel that is not a power-driven vessel (for example, a vessel at anchor or a vessel not under command) uses additional short blasts along with a prolonged blast to identify her status.

✅ Before You Answer

• Verify in Rule 35 what is required for a sailing vessel underway in or near an area of restricted visibility • Confirm the time interval at which the fog signal must be sounded for vessels underway (even if not asked, it helps confirm the pattern) • Check whether abaft the beam (the wind direction) changes the required fog signal, or if the same signal applies to all sailing vessels underway regardless of point of sail
