Maritime Navigation Rules And Vessel Responsibilities International And Inland Regulations Practice Test

What operation is indicated by two cones apexes together?

Vessel trawling Vessel at anchor Vessel not under command Vessel engaged in towing

Correct Answer:

Vessel trawling

Explanation:

Two cones apexes together form a specific day shape used to indicate a fishing vessel that is actively trawling. This signal is designed to be clearly recognizable in daylight so other ships know to keep clear and anticipate lines or gear extending from the vessel. It’s a distinct symbol from other listed activities: a single ball signals that the vessel is at anchor, and a ball over a diamond indicates not under command. Towing has its own signaling arrangement, which is different from two cones apex-to-apex. So the two-cone apex-to-apex shape is the designated signal for trawling.
