🔍 Key Concepts

• Meaning of a sector light on nautical charts • Purpose of a red sector versus a white sector on a lighthouse light • How chart notes and legends describe danger areas, shoals, or obstructions

💭 Think About

• Ask yourself: When you see a colored sector (red or green) on a light, what is that color usually warning you about relative to your vessel’s safe track? • Consider what part of the light’s description tells you the rhythm (flashing, occulting, etc.) and what part tells you about hazards or safe water. • Think about where a mariner would most need extra warning: in the center of a channel, or when getting too close to hazards like shoals or rocks?

✅ Before You Answer

• On a chart, verify how sector lights are drawn: look at the arcs and color shading around the light symbol. • Check what the chart legend or pilot book says about red sectors—do they mark safe water or warn of shoals/rocks/obstructions? • Confirm that the characteristics of the light (Fl, Oc, Iso, color) are listed in text, while colored sectors are used for a different purpose.
