Your vessel is being assisted by an icebreaker. How should you indicate that you are ready to cast off the towline?

🔍 Key Concepts

• Icebreaking and towing communications • International Code of Signals (letters and numerals) • Whistle signals used for maneuvering vs. special operations

💭 Think About

• Think about whether this situation is about maneuvering in restricted visibility, normal meeting/crossing/overtaking, or about a special towing/icebreaking operation. • Ask yourself: are ships more likely to use a visual signal (flags/boards) or a sound signal to confirm readiness to cast off a towline in ice? • Consider which of the given choices is specifically associated with towing/icebreaking operations, not general collision-avoidance whistle signals.

✅ Before You Answer

• Identify which option refers to a specific International Code signal used in ice or towing assistance. • Separate collision-avoidance whistle signals (used under the Navigation Rules) from operational signals (used between cooperating vessels). • Verify which signal in the list is not normally used to indicate danger or doubt, but rather to convey a specific pre-arranged meaning.
