🔍 Key Concepts

• Great Lakes icebreaker sound signals used in restricted visibility or special operations • Differences between International Code of Signals (single-letter flags) and special local signals • How a ship's whistle can be used to supplement or replace visual signals like flags or lights

💭 Think About

• Think about why icebreakers on the Great Lakes would need a special signal on the whistle. What are they trying to warn nearby vessels about? • Consider which single-letter signal is commonly associated with icebreaking or special operations, and how that might translate from a visual signal to an audible one. • Ask yourself: is this letter commonly tied to a word or operation that relates to ice, restricted movement, or escorting other vessels?

✅ Before You Answer

• Verify which single-letter signal is specifically noted in Great Lakes ice navigation guidance for icebreakers. • Confirm that the chosen letter is one that can be expressed by sound signal (short and long blasts) on the whistle and is actually prescribed for that purpose. • Make sure you are not confusing general International Code of Signals flag meanings with the special rules that apply only to Great Lakes icebreakers.
