Q

What do red sectors of navigation lights warn mariners of?

🔍 Key Concepts

• Lateral marks and sector lights on charts and buoys • How colored sectors (red/green/white) indicate safe vs. dangerous water • What hazards are usually located close to a light’s red sector

💭 Think About

• When a chart shows a light with red and white sectors, what does the white sector usually indicate about the water there? What does that imply about the red sector? • Think about which type of hazard is fixed in position and shown clearly on charts so that a light can be aimed or sectorized toward it. • Consider which option describes a danger that would be permanent and predictable enough to be marked by a specific color sector of a light.

✅ Before You Answer

• On a chart, check what dangers are often aligned with the limits of the red sector around a lighthouse or beacon. • Ask yourself: which choices are permanent, charted dangers versus temporary or moving hazards? • Confirm from light lists or chart symbols what red, green, and white sectors are commonly used to mark.
