BOTH INTERNATIONAL & INLAND A vessel engaged in mine clearance operations shows special identity lights. Which is a requirement of these lights?

🔍 Key Concepts

• Rule 27 – Vessels Not Under Command or Restricted in Their Ability to Manoeuvre (mine clearance is a special case in this rule) • Difference between navigation lights of a power-driven vessel (masthead, sidelights, etc.) and additional special identity lights • The color and arc of visibility for masthead lights vs. all-round lights

💭 Think About

• First, decide whether mine clearance lights replace or are in addition to the normal power-driven vessel lights • Compare the stated color and arc (in degrees) in the options with what you know about a masthead light versus an all-round light • Think about what mine clearance operations imply for safe passing distance and check what distance is actually specified in the Navigation Rules

✅ Before You Answer

• Check Rule 27 in the Navigation Rules and confirm whether mine clearance lights are additional to the standard lights • Verify whether the special mine clearance lights are all-round (360°) or limited to 225° like a masthead light • Confirm from the rule the exact minimum approach distance specified (verify the number of meters in the current text)
