Special marks
A
special mark is a sea mark used in maritime pilotage to indicate to
the Mariner a special area or feature, the nature of which is
apparent from reference to a chart. Special marks can indicate:
anchorage areas, mooring areas, pipelines, spoil ground (an area
where dredged material is deposited); cables; recreation zones.
Topmark. The special buoy carries a yellow cross.
Colour. Yellow is the colour used for Special marks.
Shape. They may have any shape but they must not conflict with those used for the other marks.
Lights. A yellow light is used. The rhythm may be any, other than those used for Cardinal, Isolated Danger and Safe Water marks. The following are permitted examples: group occulting; flashing; group flashing with a group of 4, 5 or 6 flashes; composite group flashing.
