At 0745, Latimer Reef Light is bearing...

🔍 Key Concepts

• Plotting a bearing from a known aid to navigation (Latimer Reef Light bearing 343° pgc) • Using a range (distance) off another point (6.9 nm from Race Point) to form a second line of position • Converting between perpendicular range arcs and visualizing where two position lines intersect on the chart

💭 Think About

• On your chart, how do you plot a line of position from Latimer Reef Light when you are given a bearing FROM your vessel TO the light of 343° pgc? Think about whether you need to reverse the bearing to get the line through the aid. • How do you represent being 6.9 nm from Race Point on the chart: as a straight line, a circle, or something else? Where does that shape intersect the line from Latimer Reef Light? • Once you have the intersection point, carefully read the latitude and longitude. Which of the answer choices most closely matches that plotted position?

✅ Before You Answer

• Be sure you understand whether 343° pgc is the bearing from the ship to the light or from the light to the ship, and plot the correct reciprocal if needed. • Double‑check that the 6.9 nm is measured correctly from Race Point using the latitude scale (minutes of latitude) for distance. • After plotting, verify both latitude AND longitude carefully against the chart to avoid mixing up tenths of minutes (0.1, 0.2, etc.).
