Which statement is TRUE for an unlighted, red and green, horizontally-banded buoy with the topmost band red?

🔍 Key Concepts

• U.S. Aids to Navigation System – lateral marks and their shapes • Meaning of red and green horizontally-banded buoys with the topmost band red (preferred channel marks) • Shape significance of can buoys (cylindrical) vs nun buoys (conical) in the U.S. lateral system

💭 Think About

• Ask yourself: In the U.S. lateral system, which color is normally associated with conical (nun) buoys and which with cylindrical (can) buoys? • How does a horizontally-banded red/green buoy differ from a solid-color red or green buoy in both meaning and sometimes shape? • Does the topmost color on a horizontally-banded buoy affect its shape, or only its navigation meaning (which side is preferred)?

✅ Before You Answer

• Verify in a U.S. Coast Pilot, Light List, or U.S. Aids to Navigation diagram how preferred channel (junction) buoys are depicted. • Confirm which side of the channel is marked by red nuns and which by green cans when returning from seaward in IALA Region B (U.S. system). • Check whether the shape of a red/green horizontally-banded buoy is prescribed (can vs nun) or whether it is listed as "shape optional / no significance".

Question 1 of 27070

Which statement is TRUE for an unlighted, red and green, horizontally-banded buoy with the topmost band red?

They are cylindrical in shape and called can buoys

They are conical in shape and called nun buoys

They are triangular in shape to indicate that it may not be possible to pass on either side of the buoy

They may either be cylindrical or conical since the shape has no significance
