FM Marine Services is an Irish boatbuilder specialising in the construction of robust, purpose-built vessels for defence, patrol, and commercial maritime operations. With a legacy rooted in the trusted Cygnus designs, we combine time-proven hulls with modern engineering to deliver reliable, mission-ready craft.

Our vessels—such as the recently delivered multi-role workboat for the Irish Naval Service—are renowned for their exceptional natural stability, providing a safe and steady platform for operations in challenging sea states. Each build is tailored to suit operational roles including training, survey, dive support, and maritime security.
