Definition
Yellow throughout, with an X-shaped yellow topmark where fitted, and a yellow light of any rhythm that cannot be confused with white cardinal, isolated danger or safe water rhythms; Fl Y 5s is typical. Special marks indicate spoil grounds, outfalls, cables, military exercise areas, recreation zones, data buoys and racing marks. Their shape may optionally reflect the lateral system, but they carry no navigational meaning beyond identifying the feature described in the pilot or on the chart.
