When making landfall at night, how can you determine if a light is a major light or an offshore buoy?

🔍 Key Concepts

• Light List use for positive identification of aids to navigation • How light characteristics (period, color, flash pattern) are published and used • Limitations of using only color or apparent intensity when identifying lights at night

💭 Think About

• Ask yourself which method gives you an objective, verifiable identification that matches official publications, rather than just what you see. • Consider whether buoy lights are always limited to only certain colors in all situations and areas. • Think about how reliable apparent brightness is when distance, weather, and background lighting can all change how bright a light looks.

✅ Before You Answer

• Verify which choice involves comparing observed information to an official publication. • Check whether any option relies only on visual impressions (brightness, simple color) that can be misleading at sea. • Confirm whether a method would still work in poor visibility or at an unknown distance from the light.

Question 1 of 27070

When making landfall at night, how can you determine if a light is a major light or an offshore buoy?

By checking the period and characteristics against the Light List

By observing the intensity of the light

By the color, because the buoy will have only a red or a green light

All of the above can be used to identify the light.
