Q

At 0250, Great Machipongo Inlet Light "5" (37°21.8'N, 75°43.7'W) bears 279°pgc. At 0320, the light bears 320° pgc. If you are making good 6.5 knots, what is the position of your 0320-running fix?

🔍 Key Concepts

• Running fix using two bearings of the same object taken at different times • Converting time difference and speed into distance run along your track • Transferring the earlier line of position (LOP) forward along the course made good to 0320

💭 Think About

• How many nautical miles do you travel between 0250 and 0320 at 6.5 knots, and in what direction is your course made good? • Once you draw both bearings from the light, where do you slide the 0250 LOP to in order to get the 0320 running fix? • After plotting the running fix, is the track line generally moving you toward the north, south, east, or west relative to the light?

✅ Before You Answer

• Be sure the time interval between bearings is correct (in hours and minutes) before you compute distance run. • Confirm that the 6.5 knots is speed made good along your track, not a speed relative to the light. • Double‑check whether your latitude is increasing or decreasing between the 0250 position and the 0320 running fix and how the longitude changes relative to the light.
