| | Lateral Special Marks Ireland IALA-A Buoyage System |
 | | These countries follow the IALA-Region A (IALA-A) Buoyage System, which is used in Europe, the Mediterranean, the Western Pacific (except for Korea, Japan and the Philippines), the Indian Ocean, and the coasts of Africa. |
 | | Lateral marks indicate the sides of a channel, and under the IALA-A System when returning to port, green marks are kept on your starboard side and red marks are kept on your port side (Green Right Returning). |
 | | If lateral marks are lighted, their lights are green (starboard side) or red (port side) in Region A. This green buoy with the letter “A” is left on our starboard side as we motor up the Firth of Clyde Channel in Scotland, passing to the west of Great Cumbrae Island. |
