Cardinal marks 3

The West Cardinal mark has a shape of a pillar or spar, and is yellow with a black horizontal band in the middle. As a top mark it has two black cones, one above the other, point to point.
The West Cardinal mark, exhibits a white light with a rhythm of 9 very quick flashes, every 10 seconds, or 9 quick flashes, every 15 seconds.
To memorize the light rhythm of the cardinal marks:
Associate the number of flashes of each group with that of a clock face.
Three o’clock is east, six o’clock is south, and nine o’clock is west.
To memorize the colors of the cardinal marks, associate the black color and the points of the double cone top mark.
For example, in the north cardinal mark, the points of the cones showing upward, indicate that the black color is on the upper part of the buoy.
In the south cardinal mark, the points of the cones showing downward indicate that the black color is on the down part of the buoy.
The same is true for the East Cardinal mark and for the West Cardinal mark.
