🔍 Key Concepts

• Specialized ice navigation procedures and agreements between an icebreaker and an assisted vessel • Differences between sound/visual signals and radio communications • Historical vs modern methods of ship-to-ship communication

💭 Think About

• Which of these methods is least likely to be part of modern icebreaking operating procedures between ships? • Think about which method is obsolete or rarely used today compared to the others. • Consider which methods allow real-time voice coordination in complex, close-quarters ice operations.

✅ Before You Answer

• Identify which option represents an outdated communication technology. • Confirm which methods allow direct, spoken instructions between bridge teams. • Ask yourself which method is least practical for fast, back-and-forth maneuvering signals in ice.
