🔍 Key Concepts

• Rule 24 – Towing and Pushing in the Navigation Rules • Color and vertical arrangement of yellow and white stern‑area lights • Differences between lights for towing vessel, vessel being towed, and fishing vessel

💭 Think About

• Look at the order of the colors from top to bottom. For which type of vessel does the Rules specifically say one color is placed above another at or near the stern? • Compare what a vessel actually doing the work (providing propulsion) must show versus what the object or vessel being moved astern must show at night. • Ask yourself: do disabled or fishing vessels ever use a yellow-over-white combination, or do they use different colors and sometimes shapes instead?

✅ Before You Answer

• Verify in Rule 24 which vessel shows a yellow light in a vertical line over a white sternlight. • Check what lights a vessel being towed shows – note whether there is any yellow light specified for the tow itself. • Confirm that fishing vessels and vessels not under command/broken down use red and white combinations, not yellow over white.
