🔍 Key Concepts

• Navigation Rules for sailing vessels’ lights when underway (power-driven vs sailing) • The meaning of different color combinations of lights (red over green, green over red) • Which lights are shown at the masthead, bow, and stern for various vessel types

💭 Think About

• For a sailing vessel underway (not using its engine), which colors and vertical order are associated specifically with sailing? • Which option describes a light used by a towing, pushing, or power-driven vessel rather than a sailing vessel? • Look at where on the vessel the lights are placed (masthead vs stern vs bow); which locations are typical for sailing identification lights?

✅ Before You Answer

• Verify in the Navigation Rules the exact phrase that describes the color order for sailing vessel identification lights at or near the top of the mast • Check which choice describes a special flashing light, and recall which type of vessel or operation normally uses that light • Confirm that stern lights for sailing vessels are normally a single white sternlight, not two white lights in a vertical line
