Lighted buoy flashes morse code "T" (one long flash) with intervals of 6 seconds


Cardinal buoys, marked in yellow and black, show where the deepest or safest water is. The North, East, South and West cardinal buoys are distinguished by their colour pattern, and by their top marks. The North cardinal buoy is black on top and yellow on bottom.

For an example of lateral buoys used to mark a (preferred) channel, see direction of buoyage below. Cardinal buoys The four cardinal buoys indicate the safe side of a danger with an approximate bearing. For example, the West cardinal buoy has safe water on its West and the danger on its East side.


When the Safe Water Mark is the seaward most buoy, (“Sea Buoy”), they are used by the navigator as the Point of Departure or the Point of Arrival when beginning or ending an offshore passage; thus marking the point between open water navigation and pilotage.

A north cardinal buoy indicates that the deepest or safest water exists to the north of the buoy. The vessel must travel north past the north buoy; in this way, the buoy is between the hazard and the craft.


Lateral Markers. These navigation aids mark the edges of safe water areas: for example, directing traffic within a channel. The markers use a combination of colors and numbers, which may appear on either buoys or permanently placed markers.
