🔍 Key Concepts

• INLAND Navigation Rules for towing alongside, especially lighting for the vessel being towed • Difference between lights required for the towing vessel and for the vessel being towed • How sidelights and stern lights are shown on a power-driven vessel underway that is not making way on her own

💭 Think About

• First, ask yourself: when a vessel is being towed alongside and is not the tug, is it treated more like a barge or like an independent power-driven vessel underway for lighting? • Which answer choices mention lights that identify a towed object versus lights that make a vessel look like a normal power-driven vessel underway? • Look in the Inland Rules section on towing and pushing: what specific lights are required on the tow itself when alongside or pushed ahead?

✅ Before You Answer

• Verify in the Inland Rules (Annex or towing sections) what lights are required on the vessel being towed alongside, not on the tug • Check whether a special flashing light is placed on the towing vessel or on the tow when alongside • Confirm whether a towed vessel alongside should show both sidelights or only the outboard sidelight, and whether a stern light is required
