Special marks
These are used to indicate a special area or feature, the nature of which may be found by consulting a chart or sailing directions.
Some local examples are the spoil ground, pipeline and recreation buoys in Port Phillip and the pilot buoy off Flinders in Western Port.
The colour of the special mark is always yellow, and the top mark, if fitted, is a single yellow X. Some special marks may be in the shape of a lateral mark. If a light is fitted it will be yellow and may have any rhythm not used for white lights, for example, Fl.Y, Fl.(4) Y.

In Victorian waters, special marks are commonly used to indicate no boating zones, special activity zones and speed restriction zones.
