INLAND ONLY A power-driven vessel when pushing ahead or towing alongside on the Western Rivers (above the Huey P. Long Bridge on the Mississippi River at mile 106.1) shall exhibit which of the following configurations?
• INLAND Navigation Rules – Western Rivers special lighting • Difference between lights for a tug pushing ahead/towing alongside vs towing astern • Meaning and placement of towing lights vs masthead and stern lights
• First, recall what lights any power-driven vessel underway must show as a basic requirement. Then ask: what changes when it is engaged in towing or pushing? • Think about where towing lights are located and what color they are. Would pushing ahead or towing alongside always require them, or only in certain configurations (e.g., astern tows)? • Western Rivers (above the Huey P. Long Bridge) have a special exception. Compare the general Inland towing lights rule to the Western Rivers modification and ask: what is added or not required there?
• Verify in the Inland Rules section on Rule 24 – Towing and Pushing and the Western Rivers exceptions note. • Confirm whether pushing ahead/towing alongside on Western Rivers needs towing lights at the stern, or instead a particular arrangement of masthead lights. • Check carefully if the question is about lights on the towing vessel only, not the entire tow – this affects which lights are required.
