Q

BOTH INTERNATIONAL & INLAND Which vessel(s) is/are required to sound a fog signal of one prolonged followed by two short blasts?

🔍 Key Concepts

• Fog signals for vessels underway and at anchor in restricted visibility (Navigation Rules, Rule 35) • Differences between signals for power-driven vessels, sailing vessels, and vessels with special conditions (e.g., not under command, restricted in ability to maneuver) • Which vessels use one prolonged blast only, and which add two short blasts

💭 Think About

• For each choice, ask: Is this vessel underway or at anchor, and does Rule 35 give it a distinct pattern of prolonged and short blasts? • Compare the required fog signals for a sailing vessel underway versus a vessel not under command—are they the same pattern or different? • Think about what extra information the pattern "one prolonged, two short" is meant to communicate about the vessel’s ability to maneuver or its status.

✅ Before You Answer

• Look up Rule 35 and verify which specific vessel types are listed with the pattern one prolonged followed by two short blasts • Confirm whether this same pattern is used only when underway, only when at anchor, or in both cases for certain vessels • Double‑check if a sailing vessel underway has its own unique fog signal pattern that is different from a power-driven vessel or a vessel restricted in ability to maneuver
