Q

An icebreaker assisting a vessel through an ice field would display a visual signal consisting of the code letter "M" (Mike). What does this signal signify?

🔍 Key Concepts

• International Code of Signals – Flag M (Mike) • Typical sound/visual signals for maneuvering and warning under the Navigation Rules • What an icebreaker might need to communicate to a following vessel in restricted conditions like an ice field

💭 Think About

• Think about what information is most important for a vessel following close behind an icebreaker in ice: which of these four options would be critical to avoid collision in that situation? • Compare the normal meanings of “I am altering my course…” versus “I am operating astern propulsion” versus “I am stopped” – which one most closely matches the standard meaning of Code flag M (Mike) in the International Code of Signals? • Ask yourself: does Code flag M usually describe a change of course, a change in engine use, or a status/condition of the vessel?

✅ Before You Answer

• Verify the standard meaning of Code flag M (Mike) in the International Code of Signals, not just in COLREGS sound signals. • Check whether the meaning of flag M is about course alterations or about the movement/condition of the vessel (ahead, astern, stopped, etc.). • Confirm whether icebreakers use the same basic signal meanings as other vessels, or if the signal takes on a specialized meaning only in the context of icebreaking.
