INTERNATIONAL ONLY Which signal may be sounded ONLY by vessels in restricted visibility?

🔍 Key Concepts

• Rule 35 – Sound signals in restricted visibility (International Rules) • Difference between maneuvering/warning signals and restricted visibility signals • Which signals are used only when you cannot see other vessels (fog, heavy rain, etc.)

💭 Think About

• First, sort each option into either: maneuvering/whistle warning signal or restricted-visibility fog signal under Rule 35. • Ask yourself: which of these signals is associated with a specific type of vessel making way or underway but not making way in fog? • Consider whether any of these signals are normally used in clear weather to communicate intentions or doubt about another vessel’s actions.

✅ Before You Answer

• Verify in Rule 35 which patterns are assigned to power-driven vessels, anchored vessels, or towing vessels in fog. • Check Rule 34 (maneuvering and warning signals) to see which of these options are used for altering course, operating astern propulsion, or doubt signals in clear visibility. • Make sure the signal you choose is not used anywhere else in the Rules except in restricted visibility.
