We understand that time and precision are critical. Whether it’s new workboat build, refit, maintenance or repair, jetty or h ... arbour infrastructure works, or marine energy device fabrication. Our name is new, but Mainstay Marine Solutions carries on a long legacy of boat building with a core management team who have been designing and building workboats for over 30 years in our deep-water facilities in Pembroke Dock, on the Milford Haven waterway in South West Wales. Responsive and exacting, we meet your critical deadlines and ensure your vessel or waterside infrastructure’s time in service is maximised, safely. Our capabilities are showcased in the pilot boats, patrol boats, wind farm support vessels, workboats, passenger vessels and tidal energy devices, recently launched and in build. read more
