• Rule 27 – Vessels Not Under Command or Restricted in Their Ability to Manoeuvre • The special signal for a vessel engaged in mineclearance operations (three all-round green lights in a triangle) • The rule that states how close other vessels may approach a mineclearing vessel

💭 Think About

• First, identify what kind of vessel shows three all-round green lights arranged with one above and two below forming a triangle. Is it fishing, towing, or mineclearance? • Once you know it’s a mineclearance vessel, look up in Rule 27 what restriction is placed on other vessels regarding how close they may approach. • Compare the exact distance stated in the rule (in meters) with the answer choices provided.

✅ Before You Answer

• Confirm in Rule 27 that three all-round green lights in a triangular pattern means a vessel engaged in mineclearance operations. • Verify the specific sentence in that paragraph that begins with something like “It is dangerous for another vessel to approach within …” • Match that exact meter distance from the rule to the closest answer choice without converting units.
