🔍 Key Concepts

• Chart legend and title block information • Standard units for soundings on U.S. vs international charts • How to recognize fathoms vs feet vs meters from contour labels and abbreviations

💭 Think About

• Look at the chart’s marginal notes: what unit is explicitly stated for soundings? • Do contour labels (like 10, 20, 30) match more typical depths for feet, meters, or fathoms in that area? • Are there any abbreviations (e.g., ‘fm’, ‘m’) or dual-unit notes that give you a clue?

✅ Before You Answer

• Check the chart title block and the note that usually says “Soundings in ___”. • Verify whether depth figures seem realistic for the coastal/ocean area if they were in feet, meters, or fathoms. • Look for any legend or note that mentions fathom curves, meter scale, or similar wording.
