Cardinal buoys

Buoyage systems and types of buoys

Buoyage systems and types of buoy The main buoayge systems that are employed are the Lateral Buoyage system and the Cardinal buoayge system. The Lateral system is subdivided into two separate systems: the IALA-A system and IALA-B system. The starboard side of the fairway is indicated by the green-coloured conical shape in the A-system, and the port side is indicated by the red-coloured can-shape. America and some oriental countries employ the B-system: starboard is indicated by a red-coloured cone, and the port is indicated by a green-coloured can. Buoys in the Cardinal system are used to indicate how to pass a danger in a certain quadrant or area. The position of the danger is indicated by North-, South-,East-, and West-Cardinal buoys. They will give the navigator information regarding the vessel’s position in reference to the position of the danger. Cardinal buoys are pillar-or spar-shaped.  

Special buoys indicate special features in the fairway that can be looked up in the Pilot book. They may haveany shape and are fitted with a yellow light. Landfall mark marks safe water of sufficient depth and indicate that one approaches the coast. They are pillar-, and spar-, or spherical-shaped and are fitted with a white light. Isolated danger marks are pillar-or spar-shaped and are fitted with a white light. Topmarks(Daymarks). They may be a can, a cone, a sphere or a cross.
