Q

At 2000 Montauk Point Light bears 010°T. At 2030 Montauk Point Light bears 348°T. Assuming that you are making good your course of 046°T and a speed of 9 knots, what is your 2030 running fix position?

🔍 Key Concepts

• Running fix using two bearings of the same object with time and DR track • How far you travel in 30 minutes at 9 knots and how to plot that on your DR course of 046°T • Transferring the earlier LOP (Line of Position) forward along the track to get a running fix

💭 Think About

• First, how many nautical miles do you travel between 2000 and 2030 at 9 knots, and in what direction is that motion plotted? • When you plot the 2000 bearing to Montauk Point, from which point do you draw that LOP, and how do you advance it to 2030? • Once both LOPs are on the chart at 2030, what feature tells you the position you are looking for?

✅ Before You Answer

• Be sure your distance run from 2000 to 2030 is correctly computed in nautical miles using $\text{Distance} = \text{Speed} \times \text{Time}$ • Verify that the track line you advance along is 046°T, not along the bearing to the light • Confirm that your running fix is taken at the intersection of the advanced 2000 LOP and the 2030 bearing LOP, and then match that plotted point to the closest latitude/longitude choice
