🔍 Key Concepts

• DR (Dead Reckoning) calculations using course, speed, time, and distance • Using the charted position of Cape Charles Lighted Bell Buoy "14" to measure distance from your 0725 fix • Relationship between knots, nautical miles, and minutes of time (speed–time–distance triangle)

💭 Think About

• From your 0725 position, plot your course of 206°T and mark the location of Buoy "14"; how do you measure the distance along your track from the fix to the abeam position? • Once you know the distance in nautical miles from your 0725 position to the abeam point, how do you convert that distance to time at 18 knots? • After you find the elapsed time from 0725, what clock time does that correspond to, and which answer choice is closest?

✅ Before You Answer

• Be sure you locate Cape Charles Lighted Bell Buoy "14" correctly on the chart and determine the point where you will be abeam (i.e., at right angles to your track line). • Double-check that you are using nautical miles (not yards or statute miles) when measuring the distance on the chart. • Confirm your speed–time–distance math: ( \text{Time (hours)} = \frac{\text{Distance (NM)}}{\text{Speed (knots)}} ), then convert hours to minutes before adding to 0725.
