You are planning to anchor your vessel at LAT 41°01.1'N, LONG 73°02.8'W. What type of bottom should you expect at this position?
• Nautical chart symbols for bottom characteristics (e.g., M, S, G, etc.) • How to use the given latitude and longitude to find the exact spot on a chart • Differences between mud vs sand and color descriptors on charts
• On a nautical chart for that area, what abbreviation would you expect to see near 41°01.1'N, 73°02.8'W, and how is it decoded? • How do chartmakers usually indicate the color or type of mud or sand in the bottom description? • If the chart only shows one main bottom type in that local anchorage, which choice best matches the likely chart abbreviation?
• Verify the exact charted bottom abbreviation at those coordinates on an official chart (e.g., NOAA)** before deciding • Confirm how the chart’s bottom legend translates abbreviations (e.g., M, S, G, f, h, etc.) • Make sure you are matching both the material (mud vs sand)** and any descriptive word (gray, soft, hard) to the chart notation
