🔍 Key Concepts

• IALA Maritime Buoyage System main mark types (lateral, cardinal, safe water, isolated danger, special marks) • The colors and patterns associated with each mark type • How vertical stripes vs. horizontal bands are typically used

💭 Think About

• First, recall what a cardinal mark looks like in terms of color pattern and topmarks. Does it ever use red and white? • Think about which buoy type is intended to show that water is navigable all around it, rather than warning you away from a specific hazard. • Match each choice with its standard color scheme and ask: which one is correctly associated with red and white vertical stripes?

✅ Before You Answer

• Verify the color and pattern for each mark type in the IALA system, not just the name. • Check which mark type indicates safe navigable water all around versus a specific danger to avoid. • Confirm whether a special mark or isolated danger mark ever uses red and white vertical stripes as its standard appearance.
