🔍 Key Concepts

• Towing light definition and color in the Navigation Rules • How lights are arranged for a vessel engaged in towing astern vs. pushing ahead/composite unit • When a towing light is shown in addition to the stern light

💭 Think About

• Think about what the towing light represents: is it used to show the presence of a tow, or a particular kind of towing arrangement? • Consider whether tow length alone changes the type of light, or just adds more lights forward on the mast • Ask yourself: in a rigid composite unit, is the towing vessel still required to show towing lights, or is the unit treated as a single power-driven vessel?

✅ Before You Answer

• Look up the definition and placement of the towing light in the Navigation Rules (Annex I and Rule 21) • Verify which rule and paragraph describe lights for vessels engaged in towing and pushing (Rule 24) • Check carefully which options refer to towing astern, any towing, and composite unit, and match those to the exact wording of Rule 24
