Entering harbour from seaward (IALA A), how do you pass this mark?
A buoy. Body: green. Topmark: a green cone, point up.
Show the answer
Keep it on your starboard side (to your right). A green cone is a starboard-hand lateral mark. Going into harbour, keep it to starboard. (In IALA B, used in the Americas, Japan, Korea and the Philippines, the colours are reversed.)
