IALA Buoyage Self Testing 

6:13 Preferred Channel Marker - Starboard is incorrect. This is a starboard lateral buoy in the Region A

I am studying the basics in navigation and in my region (South América - Brazil) IALA-B is used. I noticed that some markers are the opposite than ours. I think you use IALA-A, isn't it?

There is one error. It's on 06:10 should be Starboard Lateral Marker not Preferred Channel Marker.

Great for the beginner. Thanks

Gives more ideas to me

thanks!!!

Please from 06:02 to 06:13 thats Incorrect

he just ignored region B
