Definition
The IALA Maritime Buoyage System document sets out the lateral, cardinal, isolated danger, safe water and special marks, their shapes, colours, topmarks and light rhythms, and defines the boundary between Region A and Region B. It also covers the emergency wreck marking buoy introduced after the 2006 Tricolor incident. National authorities implement it through their own regulations, and the essentials are summarised in Chart 5011 and in every yachting almanac.
