🔍 Key Concepts

• IALA Maritime Buoyage System and the purpose of an isolated danger mark • How light groups and rhythms help distinguish different buoy types at night • Difference between group flashing, quick flashing, and long flashing in buoyage

💭 Think About

• Ask yourself: an isolated danger mark shows a danger with safe water all around—would its light pattern need to be especially distinctive or just moderately distinctive? • Compare which of the listed light rhythms are typically used for other marks (like cardinal or special marks) and eliminate those that don’t fit an isolated danger mark. • Think about which option best matches a "group" pattern that repeats, rather than a continuous or very high-frequency flashing.

✅ Before You Answer

• Verify which light phase characteristic is specified in the IALA buoyage tables for an isolated danger mark. • Check that the chosen characteristic is a group of flashes and not a single long flash or a continuous high‑frequency flash. • Confirm that the option you pick is not commonly associated with cardinal marks, which use quick or very quick flashing patterns.
