🔍 Key Concepts

• Safe Water Mark purpose and where it is used in the IALA buoyage system • Day shapes and colors for safe water marks • Light color and light characteristics commonly used on safe water marks

💭 Think About

• Think about what a mariner should visually recognize from a distance (by day and by night) to know the water is safe all around the buoy. • Consider whether a safe water mark has just one identifying feature or a combination of color pattern, shape, and light. • Ask yourself which of the options could reasonably appear together on the same buoy type in the real world.

✅ Before You Answer

• Verify the color pattern used on safe water marks (horizontal vs vertical stripes, and what colors). • Confirm the day shape/topmark used for a safe water mark (what geometric shape?). • Check what color of light is associated with safe water marks in the buoyage system.
