A cardinal mark showing an uninterrupted quick-flashing white light indicates the deepest water is located in which quadrant?

🔍 Key Concepts

• IALA cardinal marks and what they indicate about safe water direction • How light rhythms (single uninterrupted vs grouped flashes) distinguish the four cardinal marks • The relationship between a mark’s topmarks (cones) and its light pattern

💭 Think About

• First, recall what a cardinal mark tells you: is the safe water located to the north, south, east, or west of the mark itself? • Think about which cardinal mark uses a continuous quick or very quick white light with no grouping (no 3, 6+long flash, or 9 pattern). • Try to match the uninterrupted quick-flashing light to the correct topmark cone arrangement and then to the correct quadrant of safe water.

✅ Before You Answer

• Verify which cardinal mark has no grouping in its light pattern (not 3, 6+LFl, or 9 flashes). • Confirm that for that mark, the safe water lies in the quadrant that shares the same name as the mark (e.g., north mark → safe water to the north of the buoy). • Double‑check you are not confusing quick-flashing groups (like 3, 6, 9) with an uninterrupted quick-flashing light.
