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.

We are renowned for our quality workmanship and pride ourselves on our ability to manufacture quality Welsh products to international customers. We offer a fully-comprehensive service from concept design to through-life support.

So whether it’s new workboat build, refit, maintenance or repair, we understand that time and precision are critical. 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.

Our extensive marine knowledge and specialist skill sets have enabled us to diversify in to the Marine Renewable Energy Sector. Our comprehensive competencies and ‘made-to-order’ business model makes us well suited to build prototypes and complex heavy industrial structures.

Research and development is fundamental within our business, many of our projects offer bespoke solutions often using the latest technology.

Mainstay have secured numerous flagship projects, developed excellent customer relationships which have secured repeat builds and have seen off international competition, through its quality and safety processes, keeping manufacturing in Wales. We have exported vessels all over the world including Pakistan, Antarctic and China.
