🔍 Key Concepts

• Navigation Rules Rule 25 – Sailing Vessels Underway and Vessels Under Oars • The optional red over green all‑round lights sometimes carried by sailing vessels • How fishing and trawling vessels show their special lights (Rule 26) and the color order (which color is over which)

💭 Think About

• Look at the two lights shown vertically in the center of the illustration: what are their colors and order from top to bottom? • Ask yourself which vessel type in the Rules is allowed to add those two vertical all‑round lights in addition to its normal sidelights. • Compare the color order in the picture with the memory aids for fishing and trawling lights (for example: which one is green over white and which is red over white?). Does the illustration match either of those?

✅ Before You Answer

• Verify which vessel in the Rules is associated with red over green all‑round lights in a vertical line. • Confirm that a dredge at work would show paired red or green lights on the obstructed or safe side, not just a single red over green pair on the mast. • Make sure you can still see the vessel’s normal sidelights in the illustration and factor those into your identification.
