BOTH INTERNATIONAL & INLAND Which is a characteristic of a "flashing light"?

🔍 Key Concepts

• Rule 21 – Definitions of lights in the Navigation Rules (COLREGS/Inland) • Difference between a flashing light and a special flashing light • The role of color, arc of visibility, and flash frequency in light definitions

💭 Think About

• Which of the options describes something that is explicitly stated in the definition of a "flashing light" in the Navigation Rules? • Look up how many flashes per minute are required for a light to be officially called a "flashing light" versus a "special flashing light". • Ask yourself: do the rules actually tie "flashing light" to a specific color or a specific arc of the horizon, or are those details tied to a different type of light?

✅ Before You Answer

• Verify in the Navigation Rules whether color is part of the definition of a "flashing light". • Check Annex I/Rule 21 for the minimum flashes per minute for a "flashing light". • Confirm whether the arc of visibility (in degrees) is mentioned in the definition of a "flashing light" or if that arc belongs to another specific light type.
