Q

When does a vessel which is being assisted by an icebreaker, display a flag hoist consisting of the code numeral "4"?

🔍 Key Concepts

• Icebreaker assistance communication procedures • Meaning of code numeral "4" in special icebreaking signals (not general navigation lights or shapes) • Conditions that are critical for an icebreaker to know immediately about the assisted vessel

💭 Think About

• Think about which situation would most directly affect the icebreaker’s ability to plan the convoy’s movement through the ice. • Ask yourself: in which of these choices is the assisted vessel no longer able to follow or maneuver as expected behind the icebreaker? • Consider which condition represents a change that is both serious and directly related to interaction with the ice – not just a routine speed change.

✅ Before You Answer

• Identify which option describes a situation where the vessel’s movement through the ice is effectively prevented, not just slowed. • Focus on the condition that means the vessel can no longer proceed without outside help from the icebreaker. • Verify that the signal is used for a specific, significant event, not for minor or gradual changes like small speed reductions.
