130 IALA Maritime Buoyage System

IALA International Association of Lighthouse Authorities

Where in force, the IALA System applies to all fixed and floating marks except landfall lights, leading lights and marks, sectored lights and major floating lights.

The standard buoy shapes are cylindrical (can) , conical ó- , spherical O , pillar A, and spar 1, but variations may occur, for example: minor light-floats

In the illustrations below, only the standard buoy shapes are used. In the case of fixed beacons (lit or unlit) only the shape of the topmark is of navigational significance.

130.1 Lateral marks are generally for well-defined channels. There are two international Buoyage Regions - A and B - where Lateral marks differ.

Port-hand Marks are red    REGION

A preferred channel buoy may also be a pillar or a spar. All preferred channel marks have three horizontal bands of colour. Where for exceptional reasons an Authority considers that a green colour for buoys is not satisfactory, black may be used.
