Basic Things To Know ✅

This image shows the day and night signals used by different types of vessels so they can be properly identified at sea.

🔆 Day Signals

During daytime, ships display shapes:
• RAM (Restricted Ability to Manoeuvre) – ball/diamond/ball shapes
• Fishing Vessel – two cones facing each other
• Sailing Vessel – no shapes unless also using the engine
• PD (Pilot Duty) Vessel – no special shapes, but has a pilot flag (not shown here)
• NUC (Not Under Command) – two black balls
• CBD (Constrained by Draft) – a cylinder shape

🌙 Night Signals

At night, ships use lights instead of shapes:
• RAM Vessel – red-white-red lights
• Fishing Vessel – red over white lights
• Sailing Vessel – red and green sidelights with no masthead light
• PD Vessel – white over red lights
• NUC Vessel – two red lights
• CBD Vessel – three red lights in a vertical line

These signals help other vessels know who has maneuvering priority and avoid collisions.
