📌 𝗗𝗮𝘆 𝗦𝗶𝗴𝗻𝗮𝗹𝘀 (𝗧𝗼𝗽 𝗜𝗺𝗮𝗴𝗲)
During the daytime, vessels use shapes to signal their status. Each shape has a specific meaning:
🔹 RAM Vessel (Restricted in Ability to Maneuver) – Displays a ball-diamond-ball shape.
🔹 Fishing Vessel – Uses two cones with tips together, indicating that the vessel is engaged in fishing operations.
🔹 Sailing Vessel – Displays a cone pointing downward if it is also using an engine.
🔹 PD Vessel (Power-Driven Vessel) – Usually does not have special day shapes.
🔹 NUC Vessel (Not Under Command) – Displays two black balls, indicating it cannot maneuver as required.
🔹 CBD Vessel (Constrained by Draft) – Displays a cylinder, indicating that its deep draft limits its maneuverability.

📌 𝗡𝗶𝗴𝗵𝘁 𝗦𝗶𝗴𝗻𝗮𝗹𝘀 (𝗕𝗼𝘁𝘁𝗼𝗺 𝗜𝗺𝗮𝗴𝗲)
At night, vessels use lights instead of shapes to communicate their status:
🔹 RAM Vessel – Shows red-white-red lights.
🔹 Fishing Vessel – Displays red over white lights.
🔹 Sailing Vessel – Uses red and green side lights, along with a white stern light.
🔹 PD Vessel – Displays a white masthead light with red and green navigation lights.
🔹 NUC Vessel – Shows two red lights, meaning it cannot maneuver.
🔹 CBD Vessel – Uses three red lights in a vertical line, indicating it is constrained by draft.
