🔍 Key Concepts

• Rule 24 – Towing and Pushing (International Rules) • Difference between lights for towing astern vs pushing ahead / towing alongside • Which lights are masthead lights vs stern lights or all‑round lights

💭 Think About

• First, recall what lights any power‑driven vessel normally shows underway at night. Then think about what extra lights are required when that vessel is engaged in towing or pushing. • Ask yourself: when pushing ahead or towing alongside under International Rules, does the vessel still show a separate towing light above the sternlight, or is the requirement focused on lights carried forward? • Look carefully at each choice and decide: which one describes a light or lights on the mast, forward, and which ones describe stern or all‑round lights that don’t match Rule 24(c)?

✅ Before You Answer

• Verify in Rule 24(c) – International exactly what a power‑driven vessel pushing ahead or towing alongside must show in addition to sidelights and a sternlight. • Check which option clearly describes masthead lights in a vertical line (these are white lights located forward on the vessel’s centerline). • Make sure you are not mixing up the signal for towing astern (which includes a towing light above the sternlight) with the signal for pushing ahead or towing alongside.
