The AMC Buoyage System (IALA) app helps people at sea to understand the meaning of each buoyage marker. The app provides a full 3D visual of the type of buoy, colour, shape and lighting sequence for night-time. Both Region A and B are included in the app. Whether you are a person just starting off in the industry or an experienced seafarer looking to refresh your knowledge, the app provides all the required buoyage information you need to steer safely at sea.
