🔍 Key Concepts

• INLAND ONLY lighting requirements for vessels pushing ahead or towing alongside (Navigation Rules, Rule 24) • Light sectors for sidelights, towing light, and special flashing light (Navigation Rules, Rule 21) • How a meeting situation in a river affects which side of the other vessel you see

💭 Think About

• Look at the diagram and decide: from vessel "A", are you seeing the port side or the starboard side of vessel "B" as you meet? Which color sidelight belongs on that side? • Think about where a towing light is located and in which direction it shines. Would that light ever be visible from nearly head-on? • For a tug pushing a barge ahead INLAND ONLY, which special light is placed at the forward end of the tow, and is that light meant to be seen from ahead or from astern?

✅ Before You Answer

• Verify the definition and arc of visibility of a towing light – does it show ahead or only over the stern sector? • Check the description and arc of visibility of a special flashing light used on a tow pushed ahead (Inland Rules). Is it visible to an approaching vessel from ahead? • Confirm which color sidelight (red or green) you should see when you are looking at the side of the vessel shown in the illustration.
