🔍 Key Concepts

• IALA-B lateral buoyage system and what it means by 'entering from seaward' • Characteristics (shape, color, numbering) of starboard-hand vs port-hand buoys • How conical buoys differ from can-shaped buoys in this system

💭 Think About

• First, recall whether a conical buoy marks the starboard or port side when entering from seaward in IALA-B. • Then, match that side with its standard color and numbering scheme (odd or even). • Finally, check whether all three statements (shape-side, color, numbering) can be true together for the same buoy type.

✅ Before You Answer

• Verify which side (port or starboard) a conical buoy marks when entering from seaward in the IALA-B region. • Confirm the standard color used for that side in IALA-B (red or green). • Confirm the standard numbering (odd or even) used for that side and see which options, if any, conflict.
