Mainstay Marine Solutions have secured funding to support the purchase of a 150/200 ton amphibian hoist.

Mainstay Marine Solutions, workboat and marine renewable energy device builders located in Pembroke Dock on the Milford Haven Waterway are set to purchase an amphibian boat hoist with the assistance of Coastal Communities Fund (CFF) funding.

The 150/200 ton hoist will be capable of lifting vessels and devices out of the water and moving around their 4.6 hectare site and into the company’s’ 4000m2 of covered workshop space. This will significantly expand Mainstay’s ability to provide customers with a clean and controlled environment for servicing vessels and devices away from the elements. 

The hoist will be a welcome addition to the areas’ existing infrastructure increasing the maximum lifting capability in the Haven from 35ton currently.

Stewart Graves, Managing Director commented ‘’We are delighted to have secured the funding from CCF, the hoist will complement our recent upgrades to our slipways to allow us to expand our capabilities. We will be able to work on more structures at any one time as we will be less dependent on slipway availability, meaning a quicker turnaround and more cost-effective solution for our customers’’.

Mainstay’s strategic location benefits from proximity to the Bristol Channel, Irish Sea and Atlantic trade routes. The new addition will complement the company’s existing facilities inclusive of a wet basin, 4 slipways (2 covered) and a ro-ro slipway. The amphibious marine hoist will be capable of lifting structures up to 35m in length with a 10m beam and a draft of 4.5m.

Nigel Johnson, Marine Services Manager commented ‘’It is essential that we continue to reinvest in our facilities to keep up with demand. We look forward to welcoming new and existing clients into our yard’’. 


CCF funding, delivered by BIG Lottery Fund encourages the economic development of UK coastal communities. The grant forms part of a total project cost with the remaining funding coming from the company’s own reserves.  Since its inception in 2014, Mainstay Marine has safeguarded 30 jobs and created 50 new positions, with 10% of the direct workforce consisting of apprentices. The additional work expected from the introduction of the hoist is said to create 5 permanent jobs and 2 additional apprenticeships.


It is anticipated that the hoist will complement the £76m Swansea City development project ring-fenced for Pembroke Port to support the Marine Renewable Sector in Wales.  Mainstay are already market leaders in the renewable industry having built the 200ton tidal energy device for Tidal Energy Ltd and an innovative wave energy converting device for their clients Wave-tricity.

The company would like to invite developers to contact the team regarding their requirements. For more information on the company go to
