🔍 Key Concepts

• Day shapes vs. lights in the Navigation Rules (shapes are the daytime equivalent of lights) • When vessels must show day signals to indicate status (e.g., restricted ability to maneuver, not under command, at anchor) • Difference between daylight vs. visibility conditions (clear vs. restricted visibility)

💭 Think About

• Ask yourself: Are shapes meant to be used only when it is perfectly clear, or whenever it is daytime, regardless of fog, rain, etc.? • Think about how the Rules pair shapes with lights: if lights are the night signal, when are shapes intended to be seen? • Consider whether the Rules ever limit day shapes to specific clock times (like 8 AM–4 PM), or if they talk more generally about hours of daylight.

✅ Before You Answer

• Verify in the Navigation Rules definitions how "daytime" and "day shapes" are described. • Check whether any rule limits day shapes to unrestricted visibility, or if they are required whenever it is daytime. • Confirm that shapes are not required between sunset and sunrise, when navigation lights (not shapes) are used to show vessel status.
