Safety - Buoys and Beacons

These are the road signs on the water. The meaning of each navigational buoy, or beacon, is found in its shape, symbol on the top (topmark) and its colours.

Take time to study the buoys to familiarise yourself with their meanings.


Channel Markers

These show well-established channels and indicate port (left) and starboard (right) sides of the channels. One of the following maybe used;

Lateral Marks (Red or Green)

Port Mark

  • a red can shape. At night, a red flashing light may be shown.


Starboard Mark

  • a green conical shape. At night, a green flashing light may be shown.


The Coming In

upon entering harbour the red port mark should be kept on the boat's port (left) side and the green mark on the boat's starboard (right) side.


Going Out Rule

when leaving harbour the red port mark should be kept on the boat's starboard (right) side and the green mark on the boat's port (left) side.
