International Organization For Marine Aids To Navigation (IALA)

The intergovernmental organisation that develops international guidance and cooperation for marine aids to navigation.

IALA produces standards, recommendations, guidelines and model courses covering buoyage, lights, vessel traffic services, digital services and related systems. Its work promotes harmonisation and supports authorities, manufacturers, service providers and mariners, while legal implementation remains the responsibility of states and relevant administrations.

The former International Association of Marine Aids to Navigation and Lighthouse Authorities changed status from a non-governmental association to an intergovernmental organisation on 22 August 2024. The new organisation is named the International Organization for Marine Aids to Navigation, while the acronym IALA remains in use.
