🔍 Key Concepts

• International Rules – Rule 24 (Towing and Pushing): Which towing lights exist under the International Rules and where they are placed on the vessel • Aspect of vessel B: From vessel A’s position in the sketch, are you looking at B’s bow or stern? Which sectors of lights are visible from that aspect? • Difference between Inland-only lights (special flashing yellow, flashing blue) and International requirements

💭 Think About

• Look at the picture and decide whether you are seeing the ahead view or stern view of vessel B. Which set of lights is visible from that direction? • For each answer choice, ask yourself: Is this light or these lights required by the International Rules for a pushing/towing vessel, and if so, are they visible from ahead or only from astern? • Consider why the question emphasizes INTERNATIONAL ONLY and the passing distance of 1/4 mile – how does that affect what optional or special lights you might see?

✅ Before You Answer

• Confirm under Rule 24 (International) where any yellow towing light(s) are located on the vessel and over what arcs they show • Verify whether a special flashing yellow light or flashing blue light are part of the International navigation light scheme, or whether they are used only under Inland rules or for special services • Make sure your final choice matches both: (1) the correct rule set (International), and (2) the correct viewing aspect (what you can see from ahead at 1/4 mile)
