🔍 Key Concepts

• Rule 24 – Towing and Pushing (lights and shapes for vessels engaged in towing) • Difference between masthead lights, stern lights, and towing lights (colors and arcs of visibility) • Special requirements for tow length over 200 meters and for vessels over 50 meters in length

💭 Think About

• Which option correctly describes a requirement that is specific to towing and matches the wording of Rule 24, rather than a general power-driven vessel rule? • How do the light requirements change when (a) the tow is over 200 meters and (b) the towing vessel itself is over 50 meters? • Is a towing light an optional substitute for a stern light, or is there a specific rule about how it is shown relative to the stern light?

✅ Before You Answer

• Check in Rule 24 whether a day shape (black ball or diamond) is required for a tow over 200 meters, and who displays it. • Verify in the rules whether a towing vessel over 50 meters is required to carry both forward and after masthead lights regardless of towing, or whether that comes from the general power-driven vessel rule (Rule 23). • Confirm whether a vessel towing astern must show both a stern light and a towing light, and how they are arranged, or if it may choose only one.
