🔍 Key Concepts

• chart color conventions on U.S. nautical charts (what magenta/purple usually indicates) • How aids to navigation (radio beacons, lighted buoys) are symbolized and colored • How depth contours and sounding information (like fathom curves) are printed on charts

💭 Think About

• Look at which of the four choices is related to depths and bottom configuration versus navigation information or restrictions. • Ask yourself: on real NOAA charts, what items are commonly drawn in magenta/purple ink—are they physical features, depth lines, or navigational/info overlays? • Think about the difference between a line showing a boundary/limit and a line showing a depth contour—do they use the same color?

✅ Before You Answer

• Verify which features on a standard U.S. nautical chart legend are shown in magenta/purple (especially radio/navigation info and special areas). • Check what color is used for depth contours and fathom curves in the chart legend. • Confirm that at least three of the options can be associated with symbols or notes that appear in magenta, and identify the one that does not.
