The Irish Institute of Master Mariners (IIMM) is dedicated to promoting safe, efficient, and professional conduct in maritime operations worldwide. As an influential organization in the public and commercial maritime sectors, the IIMM collaborates with government bodies, including the Irish Ministers for the Marine & Natural Resources and Transport, to provide consultation on maritime legislation and policy. They also engage with other organizations and individuals who share a common interest in maritime operations.

Membership with the IIMM offers numerous benefits, such as knowledge sharing with like-minded professionals, updates on significant legislation affecting Irish Mariners, consultation on maritime policy and legislation in Ireland, and opportunities for networking in social settings. The IIMM is a member of the International Federation of Shipmaster's Associations (IFSMA) and the Confederation of European Shipmaster's Associations (CESMA). Master Mariners who hold an internationally recognized Certificate of Competency qualify to command ocean-going vessels.
