🔍 Key Concepts

• IALA Maritime Buoyage System lateral marks (port and starboard) and how their colors are used • How preferred channel marks are shown when a channel splits or there is a main vs. secondary route • Difference between isolated danger marks and lateral marks in terms of color and shape

💭 Think About

• Think about what situation would require both red and green to be shown together on the same buoy rather than just one color. • Ask yourself: when a channel divides, how does the buoy tell you which side is the main or preferred channel? • Compare the color pattern and banding in the question to the standard patterns for isolated danger marks and special marks.

✅ Before You Answer

• Verify which mark type uses red and green horizontal bands together in the IALA system. • Confirm what colors and shapes are used specifically for isolated danger marks (to eliminate that option). • Check the IALA description of special marks (such as spoil grounds or fishing areas) and note their standard color and topmark.
