🔍 Key Concepts

• Charted rocks and islets on official nautical charts • Differences in type style (upright vs. sloping/italic letters) on charts • How charts distinguish permanent land features from submerged or awash dangers

💭 Think About

• Look at how other named chart features (like islands, reefs, underwater rocks) are printed. What does the style of lettering usually tell you about whether something is above water or underwater? • Compare this rock’s name style to the way the chart prints names of small islands versus submerged rocks. Which choice best matches a feature that would be shown with vertical letters? • Ask yourself: would the chart use the same lettering style for something that is only sometimes visible or whose position is uncertain as it does for a clearly defined land feature?

✅ Before You Answer

• Check how your specific chart’s legend explains upright/vertical vs. italic/sloping type for names. • Verify which charted features are considered always above water versus covered or awash and how each is labeled. • Confirm that you are focusing on the lettering style (vertical), not the rock’s symbol or depth soundings, when choosing your answer.
