🔍 Key Concepts

• Measuring distance along the charted federal project channels (not straight-line distance) • Following the dredged/improved channel route from the trestles to Chemphalt Wharf • Using the nautical mile scale on the chart to add up each channel leg

💭 Think About

• Are you tracing the exact path your vessel would follow in the marked channels, including all bends and turns, rather than measuring directly point-to-point? • Have you broken the route into separate legs between aids or bends in the channel and measured each one before adding them together? • Are you sure you are reading the correct distance units on the chart scale and not confusing statute miles with nautical miles?

✅ Before You Answer

• Confirm you are staying strictly within the federal project (dredged/improved) channels shown on the chart for the entire route. • Double‑check each measured leg with the chart’s distance scale in nautical miles, being careful not to mix units. • Verify that your final total distance reasonably matches the sum of all measured legs, and that you did not accidentally skip a bend or short leg near the wharf.
