Safe Water marks serve to indicate that there is navigable water all round the mark and do not mark a danger. Safe water marking can be used for fairway, mid-channel, centre line or landfall marks.

This mark may also be used to indicate channel entrance, port or estuary approach, or landfall. The light rhythm may also be used to indicate best point of passage under bridges.

Colour of safe water marks

Buoys are coloured red and white.
