Stewart Graves , Mainstay’s Managing Director commented ”The additional tonnage capability will allow us to service vessels we have previously had to turn away. Our marine servicing sector is a key part of our business, it is essential that we continue to reinvest in our facilities to keep up with demand”.

Mainstay Marine Solutions, workboat builders and servicing specialists in South West Wales have completed a major overhaul of their existing marine servicing facilities.

The company has nearly doubled its slipping capability from 350ton previously, to 650tons with the introduction of a new trolley recovery system. The trolleys will be capable of slipping vessels up to 650ton directly into one of their undercover sheds.

Located in the deep-water port at Pembroke Dock on the Milford Haven Waterway the yards’ strategic location benefits from proximity to the Bristol Channel, Irish Sea and Atlantic trade routes.

Fabricated in-house, the trolleys will be capable of slipping 45m long vessels with a maximum 12m beam and 4m draft.

The new additions will complement the company’s existing facilities inclusive of a wet basin, 4 slipways (2 covered) and a ro-ro slipway.

The investment forms part of a larger facilities upgrade where Mainstay are also in the final stages of purchasing a 150T/200T amphibian boat hoist with the assistance of Coastal Communities Fund (CFF) funding. The hoist will be capable of lifting vessels out of the water and moving around the site and workshops as necessary.

Nigel Johnson, Marine Services Manager commented ‘’Clients are requesting more and more that certain work is undertaken in more controlled environments away from the elements, the investment in our facilities helps to address this. We look forward to welcoming existing and new customers into our yard’’.

Mainstay services a variety of steel and aluminium commercial workboats including patrol, pilot boats, survey, passenger and crew transfer vessels.

The company would like to invite boat owners, operators and charterers to contact the team regarding their requirements.
