🔍 Key Concepts

• Using radar range and bearing to plot a line of position (LOP) from a fixed aid to navigation • Understanding reciprocal bearings (bearing from you to the light vs. from the light to you) • Relating the plotted point to the chart’s latitude and longitude grid

💭 Think About

• On the chart, from which known point will you start your plot: from your vessel or from Branford Reef Light? Why? • If the light bears 070° true from your vessel, what is the reciprocal bearing from the light to your vessel, and in which general direction (NE, SE, SW, NW) does that point lie from the light? • Once you place a point 2.55 nm along that reciprocal bearing from the light, does that point lie slightly east or west, and slightly north or south, compared to the light’s latitude and longitude?

✅ Before You Answer

• Be sure you use the reciprocal bearing from the light to your vessel when plotting from the light • Confirm that the 2.55 nm distance is measured accurately on the chart scale along the correct bearing line • Check whether your plotted position’s latitude (N/S) and longitude (E/W) differences from the light match the pattern in the answer choices (higher vs. lower degrees/tenths) before choosing
