🔍 Key Concepts

• IALA-B lateral system – remember the saying "red right returning" when coming from seaward • Difference between starboard-hand and port-hand buoys: both color and shape matter • How conical (nun) and cylindrical (can) shapes are used in the lateral system

💭 Think About

• When you are entering from seaward, which side of your vessel is starboard, and which color buoys are kept on that side in IALA-B? • For the buoys on the opposite side (port side) in IALA-B, what is their standard color and typical shape? • Looking at the four illustrations, which buoy has the correct combination of color and shape to mark the port side of the channel when entering?

✅ Before You Answer

• Verify which color marks the starboard side vs the port side in IALA-B when returning from sea • Check which shapes (conical/nun vs cylindrical/can) normally go with starboard vs port lateral buoys • Eliminate any option whose color–shape combination does not match a standard IALA-B lateral mark for the port side when entering from seaward
