🔍 Key Concepts

• Navigation Rules Rule 26 – Fishing Vessels (trawling vs other fishing) • The color pattern green over white and what type of fishing it indicates • How towing and dredging/restricted ability to maneuver lights differ (multiple white mastheads, red‑white‑red, side red/green)

💭 Think About

• Look closely at the colors and vertical order of the three all‑round lights. Which of the four operations is the only one commonly associated with a green light above white? • Ask yourself: for towing astern over 200 meters, what colors are the three masthead lights, and do any of them turn green? • For dredging or laying cable, what is the standard restricted‑ability‑to‑maneuver light pattern, and does it match a single green over two whites?

✅ Before You Answer

• Verify in Rule 26 whether green over white is linked to a specific type of fishing operation. • Confirm that towing astern uses only white masthead lights (plus a yellow towing light aft), not green. • Check that dredging/underwater operations normally show red‑white‑red vertically, with extra red or green lights to mark the obstructed and safe sides.
