🔍 Key Concepts

• Range lines / transits – what it means when two aids are "in line" • Using a single visual bearing (010° pgc to Cape Charles Light) to plot a line of position (LOP) • Interpreting charted information around the Chesapeake Bay entrance: danger areas, light sectors, and distances off the beach

💭 Think About

• On the chart, draw the 010° pgc bearing to Cape Charles Light as a line of position. Then, use the fact that Cape Henry Light and CBJ buoy are in line to create a second line of position. Where does that put your vessel relative to the shoreline? • Look closely at how distances from the beach or nearest point of land are marked in that entrance area. Which charted distance most closely corresponds to where those two lines of position intersect? • Check the light sectors for Cape Henry Light on the chart. From the position you’ve plotted, would you be in the red sector, white sector, or outside the sector entirely?

✅ Before You Answer

• Confirm on the chart what "in line" (Cape Henry Light and CBJ buoy) means in terms of a transit or range line through your vessel’s position. • Verify the exact distance scales given near the entrance—especially any annotations like "distance off beach" or ringed distance arcs from a point of land. • Check the sectors for Cape Henry Light: colors, bearings, and limits, then compare your plotted position’s bearing from that light to see if you fall in the red sector.
