🔍 Key Concepts

• Understanding chart features around Point Judith, including submarine cables, cable areas, fathom curves, and the boundary between Inland and COLREGS/International Rules • Position relative to charted features using given ranges (1.2 nm and 1.9 nm) to two known points • How to use a large-scale chart to relate the fix to special zones and depth contours

💭 Think About

• Plot your position using the given ranges to the Main Breakwater Center Light and Point Judith, then ask: What special areas or limits are near that location? • Compare your plotted position with the chart symbols: Do you see charted submarine cables, a labeled cable area, the 10-fathom curve, or the demarcation line between Inland and International Rules nearby? • Think about which of the four answers is tied to a line or boundary versus a broad area and whether your plotted position would fall exactly on a line or just somewhere within an area.

✅ Before You Answer

• On the chart, verify exactly where the Inland/International demarcation line is relative to the Point Judith breakwater and your plotted position • Check whether the plotted position lies on a specific cable symbol, merely within a larger cable area boundary, or outside any such markings • Locate the 10-fathom (60-foot) depth contour near Point Judith and confirm whether your plotted position is inside or outside that contour
