INLAND ONLY You see the lights shown in illustration D085RR below while proceeding in a channel. Where should you pass?

🔍 Key Concepts

• INLAND ONLY: Lights for a vessel restricted in her ability to maneuver (RAM) under Rule 27 of the Inland Navigation Rules • Meaning of red over white over red all‑round lights and the additional red-red and green-green all‑round lights used by a dredge or vessel engaged in underwater operations • How the green and red additional lights indicate the side on which you may and may not pass a dredge in a channel

💭 Think About

• Look closely at the vertical stack of three all‑round lights (red‑white‑red). What type of vessel does that indicate, and what kind of restriction does it have in the channel? • On that same vessel, compare the two vertical pairs of all‑round lights—one pair green, one pair red. Which color marks the safe side for passing, and which marks the obstructed side? • Once you identify the safe side of the dredge, which lettered track (A, B, C, or D) lines up with that side while keeping you clear of the obstruction and the river banks?

✅ Before You Answer

• Identify the light combination red over white over red as a specific status under Rule 27 – Vessels Not Under Command or Restricted in Their Ability to Maneuver • Confirm which color pair (green-green vs red-red) marks the side where another vessel may pass for a dredge or underwater operations vessel • Verify that your chosen route keeps you on the green side of the dredge and clear of the red side (obstruction) and the river banks before selecting A, B, C, or D
