🔍 Key Concepts

• Rule 24 – Towing and Pushing (International Rules) • Difference between astern tow, pushing ahead, and towing alongside • Which lights indicate a towing operation versus restricted in ability to maneuver or normal power-driven vessel

💭 Think About

• First decide: is a vessel pushing ahead or towing alongside considered a towing vessel under the Rules? If yes, what is the basic towing light pattern? • Look at each choice: which options clearly belong on the stern of a towing vessel, and which belong on the mast? Which are for towing length indication vs. special conditions like restricted maneuverability? • Ask yourself: for pushing ahead or towing alongside, what does the Rule say about the masthead lights arrangement compared to an ordinary power-driven vessel? Same, fewer, or extra lights?

✅ Before You Answer

• Verify in Rule 24 (International) what additional lights a power-driven vessel engaged in towing must carry in addition to her sidelights and sternlight. • Check which lights in the options are specifically described as masthead lights versus stern towing lights or all-round lights in the Rules. • Confirm that the pattern you choose matches a vessel that is actively engaged in towing/pushing, not just a normal power-driven vessel or a vessel restricted in her ability to maneuver.
