🔍 Key Concepts

• Navigation Rules – Rule 26 (Fishing Vessels) • Special light configurations: what color over what color, and in what order (top to bottom) • Difference between lights for fishing/trawling, pilot vessels, and sailing under power

💭 Think About

• For each choice, recall its special light pattern at night: what colors are shown, in what order (top/bottom), and whether they are all‑round or masthead/sidelights • Think about which vessel type uses a green over white combination specifically to indicate the nature of its work • Ask yourself: which of these vessel types must be clearly recognized at a distance because of its restricted maneuverability due to gear, and therefore has a distinctive two‑color vertical signal?

✅ Before You Answer

• Check Rule 26 in the Navigation Rules for fishing and trawling lights and note which color is on top • Verify which vessel type shows white over red (not green over white) so you can eliminate that option • Confirm that a sailboat under both sail and power is considered a power‑driven vessel for lights, and see if that configuration includes a green over white vertical pair over the sidelights
