🔍 Key Concepts

• IALA cardinal marks and what each direction (North, South, East, West) looks like in terms of light groups • The relationship between the number of flashes and a "clock face" memory aid • Difference between quick (Q) and very quick (VQ) light rhythms in the cardinal system

💭 Think About

• Think about how mariners remember which side is safe using the number of flashes and a clock-face trick—what time on a clock does 9 suggest, and which cardinal point matches that? • Recall the standard flash groupings: which direction uses continuous quick/very quick, which uses 3 flashes, which uses 6 + 1 long, and which uses 9? • Match the described light rhythm (9 flashes every 15 seconds) to the correct cardinal direction before deciding which side is safe.

✅ Before You Answer

• Verify in an IALA chart or light list what 9 quick or very quick flashes means in the cardinal system • Confirm that you are not mixing up the pattern 6 flashes + 1 long with the pattern of 9 flashes • Once you identify the correct cardinal direction, recall that the name of the cardinal mark tells you on which side the safe water lies (e.g., for a West cardinal, safe water is to the west of the mark).
