Battens & Hardware
Built for the Sail, Designed for Performance.
Behind every fast, reliable sail is a batten system doing the heavy lifting — and for over 30 years, C-Tech has been the leading supplier trusted by America’s Cup teams, offshore campaigns, sailmakers, and classes around the world.
Whether you’re chasing every ounce of performance in an 18ft skiff, relying on durability and speed in an IMOCA across the Southern Ocean, or looking for low-maintenance ease on your cruising cat — every C-Tech batten is custom-built to meet your boat, sail, and spec.
Our range includes:
Solid Plate Battens
For dinghy classes, Moths, and jibs where space and stiffness are key.
Hollow Tube Battens
From CT22s for 30-footers up to CT40s for 200ft+ superyachts — precision-tuned for flex and loaded performance.

Whether it’s a single one-off or a complex integrated system, we provide composites built to perform, endure, and impress.
Marine Tubes
Marine Tubes — Engineered for Strength and Precision

C-Tech specialises in producing marine-grade carbon fibre tubes made to order for a wide range of high-load and structural marine uses. Using roll-wrapped prepreg and autoclave curing, each tube achieves optimal fibre alignment, minimal void content, and excellent stiffness-to-weight ratios.
Our custom tubes often become critical components in:
Compression struts and accumulator cylinders designed to withstand high loads
Tuna tower frameworks and foldable chaseboat masts crafted for strength and corrosion resistance
Superyacht awnings, stanchions, swim ladder tubes, and telescopic masts requiring precision and durability
Tender fender tubes and other specialised marine assemblies tailored to project requirements
We collaborate closely with designers and builders to deliver tubes engineered exactly to the specs and demands of your marine build — whether for racing, commercial, or recreational vessels.
Foils
High-Stiffness Foils & Reinforcements
Engineered for elite-level performance — built to withstand the forces of high-speed foiling and offshore racing.
Using prepreg carbon fibre, precision moulding, and autoclave curing, our components are manufactured for extreme loads, low drag, and tight dimensional tolerances. We specialise in large or repeatable foil projects where consistency, accuracy, and performance are critical.
Whether it's:
Production-run high performance one-design foils for SailGP or the International Moth class
Custom lifting foils, canards, and reinforcement structures
Rudders and rudder stocks for offshore racing and high-performance yachts
We partner with you to deliver tailored solutions that meet your structural loads, weight targets, and hydrodynamic goals. These are not off-the-shelf dinghy components — they’re performance-grade systems built for serious speed.
America’s Cup
Aerodynamic Systems Built to Perform Under Pressure
Precision composite engineering honed in elite sailing — now applied to UAVs, missile platforms, and aerodynamic defence systems.
C-Tech supplied carbon fibre components to multiple America’s Cup teams, including foils, wings, and load-bearing structures. These ultra-light, fatigue-resistant components were engineered for speed, control, and aerodynamic efficiency — the same principles that now underpin our work on defence-grade UAV fuselages, control arms, and loitering munitions.
Wireline Logging
Built for Harsh Environments. Trusted to Protect Payloads.
Originally developed for geophysical sensor systems, these ruggedised carbon fibre tubes now support defence field tech and mobile surveillance applications.
Designed for the oil and gas sector, our wireline tubes withstand shock, vibration, and repeated mechanical load in extreme terrain. With precision-machined interfaces and proven fatigue resistance, these tubes now serve as structural enclosures for tactical communications, field-deployable sensors, and ruggedised defence payloads.
Ice Drill
Modular Strength for Expeditionary and Recon Platforms
Engineered for lightweight performance in polar expeditions, our modular tube systems are ideal for mobile, mission-critical defence systems.
Developed for deep ice drilling missions in Antarctica, this modular carbon fibre drill string was designed for easy field transport and high axial strength. These same capabilities make it ideal for military recon equipment, portable antenna masts, or remote field systems — anywhere ultra-light, strong, and field-assembled components are needed.
Telescopic Comms Tubes
Deployable Carbon Fibre Tubes for Tactical Comms & ISR
Large-diameter carbon tubes custom-built for defence clients needing fast-deploy, corrosion-resistant comms infrastructure.
These telescopic carbon fibre systems are used to deploy antennas, radar equipment, and mobile surveillance gear in operational defence environments. With custom interface design, high stiffness, and rapid extension/retraction features, they provide reliable performance in field communications, observation, and tactical command systems.
Space Composite
Capabilities.
Our aerospace composites manufacturing delivers the precision, repeatability, traceability and performance required by space programme integrators and carbon fibre manufacturers.
Autoclave Curing
Void-free consolidation under heat and pressure.
Our pressure- and temperature-controlled autoclave cures components up to 15.3 m long and 1.44 m in diameter. Operating at up to 180°C and 7 bar, autoclave curing ensures optimal fibre compaction and resin flow — producing void-free, high-integrity laminates trusted in space, marine, and defence.
Prepreg Accuracy
Consistent fibre alignment, optimal resin content.
We exclusively use aerospace-grade prepreg materials for tightly controlled resin content and fibre orientation. Combined with our temperature- and humidity-controlled clean room and automated ply cutting systems, we achieve consistently high laminate quality across every part — from one-off prototypes to production runs.
CNC Precision
Exacting tolerances, repeatable results.
Our Routech R200 5-axis CNC router handles subtractive manufacturing of moulds, jigs, cores, and finished parts — with an XYZ bed size of 5,500 mm × 1,500 mm × 1,000 mm. We also operate a 1.5 m ×10 m Eastman S125 flatbed plotter for ply kit cutting. This automated accuracy streamlines production and ensures every part fits and performs precisely as designed.
Advanced Tooling
High-performance tooling for high-performance parts.
We manufacture carbon fibre, aluminium, and board tooling in-house — supporting complex one-offs and reliable production runs. Our proprietary roll-wrapping machines deliver precise laminate consolidation for tubular structures up to 15 m long and 1200 mm in diameter. We also offer additive manufacturing (3D printing) in plastic and titanium —ideal for prototypes, short runs, and complex geometries that can't be machined.
Quality You Can Trust
Built-in quality at every step.
We apply stringent quality control throughout the manufacturing process —including ultrasonic non-destructive testing (NDT), dimensional QA, and resin system traceability. From OEM marine hardware to aerospace components, our parts are made to perform— and proven in the most demanding real-world conditions.
Design Capability
In-house design. Tailored engineering. Real performance.
Our experienced design team combines deep composite knowledge with practical engineering skill. We offer full design and laminate development, mechanical simulation, tooling design, and iterative prototyping — ensuring your product is strong, light, and built for its environment.
