What are the rules for cardinal buoys?
Boaters will be safe if they pass north of a north mark, south of a south mark, east of an east mark and west of a west mark
The north cardinal buoy indicates that navigable waters are north of the north cardinal buoy. It's coloured yellow and black and has a different flashing white color light on the top. How the strips are placed tells you which of those navigation markers buoy you encounter, i.e. a north cardinal buoy, a south cardinal buoy, a west cardinal buoy or a east cardinal buoy.
