National Maritime Authority The National Maritime Authority (Autoridade Marítima Nacional) or AMN is the public body responsible for most of the coast guard type activities in Portugal, including the security, safety, life-guard, lighthouses and pollution fighting at sea. For hundreds of years and until 2014, the maritime authority role in Portugal was performed by the Navy, with the AMN constituting a branch of it. However, due to the constitutional issues of having a branch of the Armed Forces performing an internal security role, the AMN was separated from the Navy in 2014, being now formally an entire separate organization. However, although legally separate, the AMN and the Navy organizations still override in many aspects. So, a single person has the double hat of being the head of the Navy (with the title of "Chief of Staff of the Navy") and the head of the AMN (with the title of "National Maritime Authority"). The same happens with other persons that have double hats (e.g. the Navy's maritime zone commanders are also the AMN heads of maritime departments, which territorial jurisdictions coincides). Besides this, the Navy continues to provide naval and other assets to the service of the AMN and continues to staff with its personnel a number of bodies of the AMN. The term "National Maritime Authority" has a double meaning, referring both to an entity and to an organization. As an entity, AMN is the person responsible for the administration and coordination of the organization, who inherently is the admiral that has the role of Chief of Staff of the Navy. This person is frequently referred as "Admiral AMN" to distinguish him/her from the AMN organization. As an organization, AMN is the structure that includes the Directorate-General of the Maritime Authority (DGAM) and the Maritime Police (PM). Among other bodies, the DGAM includes itself the Life Guard Institute, the Directorate of Lighthouses, the maritime departments, captaincies of the ports and maritime delegations, the Sea Pollution Fighting Service and the Maritime Authority School. The National Maritime Authority is part of the Maritime Authority System, which includes other public agencies that also perform authority duties at the sea.
