🔍 Key Concepts

• IALA buoyage system and the meaning of an isolated danger mark • Characteristics of special light rhythms, especially a group of 2 white flashes • Difference between buoys that tell you a required direction of passage versus buoys that simply mark a hazard to be avoided

💭 Think About

• Ask yourself: Does an isolated danger buoy tell you to go to a specific side (north, south, etc.), or does it tell you something more general about how to navigate around it? • Think about what the words "isolated danger" imply about the size and location of the hazard relative to the buoy itself. • Compare this buoy to a cardinal mark: which one gives you a mandatory direction (N/S/E/W), and which one just warns you of a spot hazard?

✅ Before You Answer

• Confirm that an isolated danger mark is identified by a black buoy with one or more red horizontal bands, and a topmark of two black spheres • Verify that the light characteristic for an isolated danger mark is a white light, group flashing 2 (Fl(2) W) • Before choosing an answer, decide whether this mark requires a specific side to pass on, or simply that you stay well clear of the danger it marks
