Buoys and Markers (continued)
You may pass these buoys on either side, but when it is marking the middle a channel it should be kept on your port (left) side.
Cardinal buoys, marked in yellow and black, show where the deepest or safest water is. The North, East, South and West cardinal buoys are distinguished by their colour pattern, and by their top marks.
The North cardinal buoy is black on top and yellow on bottom. The safe water lies to the north of this buoy.
The East cardinal buoy is black with a yellow band. The safe water lies to the east of this buoy.
