🔍 Key Concepts

• Running fix: how to advance or retire a Line of Position (LOP) to a later time along your course and speed • Parallel indexing / transferring a bearing on the chart from one time to another to find the intersection of LOPs • Converting a per gyro compass (pgc) bearing to a true bearing using the gyro error given in the problem setup/chart

💭 Think About

• Start from your earlier LOP (from the earlier bearing or fix) and carefully advance it to 0507 using your course and speed—where will that LOP be at 0507? • Plot the 0507 bearing of Stratford Shoal Middle Ground Light as a true line of position on the chart—where does it cross your advanced LOP? • Once you see the intersection point on the chart, read off the latitude and longitude carefully and compare it with the choices, watching tenths of minutes very closely.

✅ Before You Answer

• Be sure you have applied any gyro error correctly to convert 208°pgc to a true bearing before plotting • Confirm you advanced your earlier LOP using the correct distance run: ( \text{Distance} = \frac{\text{Speed (kn)}}{60} \times \text{Time (min)} ) and along the correct course line • Double‑check which side of the light your bearing line should lie on and that the intersection point really matches both your DR track and the geometry of the plot
