How did you get on with the little video of IALA lights?
Here are my thoughts
Bottom right. Fl(2)G.7s Stbd buoy
Top right Q(3)8s Easterly Cardinal
Bottom left Fl(3)R.9s Port buoy
Top centre Fl(2+1)G.11s Preferred channel to port
IALA stands for what was the International Association of Lighthouse Authorities, it is now known as International Association of Marine Aids to Navigation and Lighthouse Authorities.
If you managed all that ..... great.
