🔍 Key Concepts

• Vessel engaged in mineclearance operations as defined in the Navigation Rules (COLREGS and Inland Rules) • The special identity lights pattern and what it is in addition to, not in place of • Required color and arc of visibility for these special lights and for masthead lights

💭 Think About

• Think about whether mineclearing identity lights replace the normal navigation lights, or are shown in addition to them • Consider what the rules say about how close other vessels may approach a mineclearance vessel – is there a specific distance stated? • Recall the exact description in the rules of the mineclearance lights: are they defined by color and arc, and if so, what are those details?

✅ Before You Answer

• Verify in the Navigation Rules description for vessels engaged in mineclearance operations that any approach restriction (in meters) is or is not explicitly stated • Check whether the rule says these special lights are shown in addition to the prescribed lights for a power-driven vessel underway • Confirm the specified color and arc of the mineclearance identity lights and compare them with the required masthead light characteristics
