🔍 Key Concepts

• IALA-A lateral marks and which color/shape is used for port vs. starboard side of the channel when returning from sea • Meaning of spar buoy shape and triangular vs. square topmarks in IALA-A • Difference between a lateral mark and a cardinal mark (north, south, east, west)

💭 Think About

• Ask yourself: In IALA-A, which color and side (port or starboard) marks do you keep on your port side when ENTERING from seaward? How does that change when heading OUT to sea? • Think about what buoy characteristics are used to show a cardinal (north/south/east/west) mark. Is a simple green spar with a single triangular topmark one of those, or is that more typical of a lateral mark? • Consider whether a buoy that may be passed on either side would normally have a specific lateral color (green/red) and a distinctive topmark, or if it would look more neutral.

✅ Before You Answer

• Identify whether a green spar with triangular topmark is a port-hand or starboard-hand lateral mark in IALA-A • Confirm that cardinal buoys use black/yellow coloring and two-cone topmarks, not simple single triangles of a lateral buoy • Check if a preferred channel mark has a combination of colors (red/green bands) and a special topmark, rather than being a single solid color
