Boe IALA

• The IALA system (Recommendation R1001) marks channels and dangers, with the same rules all over the world.
• There are six types of mark: lateral, cardinal, isolated danger, safe water, special and new danger (emergency wreck marking).
• Each mark is identified by its colour, shape, topmark (the figure on top) and, at night, its light.
• A mark gives information, but responsibility for navigation stays with the skipper: always check the chart too.

Remember. At any buoy, ask yourself in this order: what colour is it? What topmark does it carry? What light does it show at night?
