Capabilities That Cover the Full Build
From first sketch to finished, survey-ready part, every stage happens in-house, giving you one point of accountability from design through delivery.
Manufacturing
Methods
Methods
Advisory services to plan, scale, and optimize solar, wind, and distributed energy systems focusing on performance, ROI, and compliance.
Five manufacturing processes under one roof, chosen to suit your material, timeline, and budget. Wet lay-up, resin infusion, prepreg, 3D printing, and CNC tooling and finishing, we select the right method for the job, not the other way round.
001
Materials & Resin Systems
A full range of marine-grade materials and resin systems, specified to suit your application. Epoxy, polyester, and vinylester resins. E-glass and carbon fibre. Aramid (Kevlar) and woven rovings. UV-resistant marine polymers and full flame-retardant options.

002
Certifications & Compliance
Integrate scalable sustainability tools into your infrastructure to boost efficiency, accuracy, and impact tracking.
Certified to the standards that matter most in marine and defence manufacturing. ISO 9001:2015 (DNV-GL Verified), Lloyds Register SSC, RINA Marine Vessel Certification, and DNV-GL Multi-Class Compliance, giving you the flexibility to build for any market.
003
Naval Architecture & Design Support
Automate ESG and carbon reporting with data pipelines for audit-ready outputs aligned with global standards.
In-house Naval Architects who optimise your design before a single part is manufactured. Full design services, plug and mould design and manufacture, and CNC tooling with 10' × 5' capacity, keeping design and production joined up from the outset.
004
Turnkey Project
Delivery
Delivery
Centralize and monitor carbon and operational data with real-time dashboards for faster, data-driven decisions.
End-to-end project management, so you get one point of contact from concept to completed vessel. Spray finishing, technical advisory, and rapid prototyping, all managed in-house to keep your project on schedule and on spec.
005
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.
What our clients are saying
“CML are a key supply partner for Oyster Yachts. The quality of work is exceptional and with a reactive management team they ensure we have everything we need, when we need it.”
"Composite Mouldings were tasked to build a very large pig to be carried around the London Marathon. Originally we expected the pig to weigh 40kg but with CML's technical advice and their ability to use different applications and materials they were able to get the pig's final weight down to 25kg! We found CML a pleasure to work with."

“Composite Mouldings has been building our Hawk 20 Dayboat and Cabin boat since they started trading. We have a good working relationship with CML and they have shared in our success with the popularity of the Hawk boats.”
"CML have been instrumental in helping us scale our business. Their speed, efficiency and knowledge are unparalleled.They've helped us as we've developed the MK5, meaning we can be confident in growing the business with their support."
"Warsash Maritime Academy provided original plans for a 365m long ship to CML to produce a model for ship handling training. CML carried out the naval architecture and structural design, achieving the correct ratios for the scale model."
"You maintain a quality management system throughout the company, and that you strive to mirror this approach to managing Health and Safety. Overall I am impressed with the standard of Health and Safety arrangements in place."
"Holyhead Marine has a well established working relationship with Composite Mouldings. They hit target, confidently build under survey and the quality is consistently good."
