Composite Manufacturing & Design
Leading GRP/Composite Manufacturer for Marine & Specialist Vessels

We've engineered complex composite solutions, since 1979.
We blend naval architecture with hands-on manufacturing expertise to turn demanding briefs into vessels and vehicles that perform. From pilot boats to amphibious craft, our approach starts with the engineering, not the sales pitch.
Complex geometry, weight optimisation, and multi-class certification aren't obstacles, they're what we're built for. Design, tooling, and manufacture all happen in-house, so nothing gets lost between the drawing board and the finished part.

Years in business
“The quality of work is exceptional and with a reactive team they ensure we have everything we need, when we need it”
- Kevin Tomlin | Compostie Manager, Oyster Yachts Ltd.
From Design to Delivery
We move through every stage with precision, from first concept to a finished, survey-ready part.
Design & Engineering
Our Naval Architects turn your brief into a 3D model, capturing complex hull curves, ribs, and undercuts with full digital precision.
Tooling & Planning
CAD is converted into CNC-ready toolpaths, optimising cutting sequences and material selection before a single cut is made.
Manufacturing
Precision CNC machining, wet lay-up, resin infusion, or prepreg, whichever process suits your project, all carried out in-house.
Quality & Delivery
Every part is verified against tolerance before finishing. Nothing leaves Marchwood until it meets Lloyds, RINA, or DNV-GL standard.
