Learn From the Leaders in Advanced Composites.

For over 35 years, we've been engineering high-performance composite solutions for some of the world's most demanding applications. From America's Cup racing to spaceflight programmes, our expertise is built on real-world challenges and proven results.

Customising Composites for Winning Teams

Go inside our precision manufacturing process for high-performance hydrofoils. Watch how computer-cut plies, laser positioning, and in-house CNC machining deliver accuracy within 0.1mm. See why dimensional stability and controlled fiber orientation create some of the world's most precise production components.

High-Performance Battens for Sail Optimisation

Follow a tangency system from robust prototype to weight-optimised final design. Watch how we use FEA (finite element analysis) combined with physical testing to align different failure modes and minimise weight. See why engineering collaboration and iterative refinement deliver components that exceed expectations.

Prototyping To Final Composite for The America's Cup

Since 2003, every America's Cup team has relied on our components. Discover how we engineer custom sail battens with specific stiffness requirements at every point along their length, and see the tangency systems that help AC75s exceed their own performance expectations race after race.

Carbon Tubing Options: Sizes, Shapes & Finishes

With over 200 mandrel shapes and sizes from 1mm to 1.2 metres, explore how we customise every aspect—from spiral-wrap finishes to painted cosmetic surfaces. Learn why short-run custom manufacturing gives you the perfect fit for your specific application, whether it's marine rigging or aerospace components.

Carbon Fibre Roll-Wrapped Tube Production

From prepreg selection to autoclave curing, discover why our continuous roll-wrapping technique delivers superior strength without the weak points found in standard lap-joined tubes. See how CNC precision cutting and controlled manufacturing conditions create tubes trusted by aerospace and marine industries worldwide.

Case Study - Antarctic Research with NIWA

When NIWA needed equipment to operate in Antarctica's harshest conditions, they chose our composites. Learn how we engineered lightweight tubes that withstand over three times the required forces while maintaining 4mm wall thickness for optimal sample collection. See why repeatability and precision matter in extreme environments.

Our Approach: Customising 
a Perfect-Fit Solution

"You don't need to be a composite expert - that's our job." Understand how we guide clients through the trade-offs of strength, weight, and cost. From defining your goals to selecting materials and manufacturing techniques, see why custom solutions outperform standard parts when your project demands unique geometry and high performance.

Trusted by Experts

We collaborate with the world’s best sailmakers, designers, and teams, and we’re proud to be a trusted supplier across every major discipline in the sport.

“Incidence Sails developed a strong, reliable and long-lasting relationship with the C-Tech products over the years, specially through the supply of the CT SailBattens range that have always matched and exceeded our highest expectations in terms of durability and stiffness compliance to our specifications. Last but not least the supply chain works perfectly even during tricky times.”

Cesar Dohy
“For over 20 years, C-Tech has consistantly delivered quality products and a professional service. We know we can rely on their composites but it's the in-house experience that really adds value. Despite being on the other side of the world, C-Tech is always on hand with advice and support.”
One Sails
John Parker, GBR
“Doyle Sails works with a significant number of Grand Prix race yachts and Superyachts globally and in nearly every project C-Tech is on-board as our supplier for carbon battens and systems. A very high quality, performance product, proudly made in New Zealand, led by a team of engineers who are constantly innovating - it is a pleasure to work with C-Tech.”
Doyle Sails
“We’ve had our C-Tech SnuffAir for 12 months now and have used it flawlessly. It’s even better than I expected actually, this is a massive sail and personally I don’t think you could beat this”
Romanza Owner

Dougall Love
“C-Tech’s flexibility in design and build, combined with a willingness to collaborate on ideas, helped in producing the best components for our needs, giving us the best results.”

Rig Construction Coordinator
“Battens play a key role in the performance of the sails. If the shape of the batten does not exactly match the shape of the sail, they fight each other and that can be quite detrimental. They must be light and strong. C-Tech are able to build specified stiffness and bend profiles very accurately and repeatedly.”
INEOS Team UK
Gautier Sergent, Head of R&D
“The Volvo Ocean Race pushes everything to the limit, C-Tech delivered on performance, durability and service.”

“C-Tech products are phenomenal. Our boat has gone better than it ever has before. Every one of their products is integral to our boat speed and durability in both cruising and racing.”
P2 Team (Briand 123)
“It has been a game changer switching to FlexiFurls. They have given us true race performance in our furling sails. Also the service has been tops, so really happy all around.”
Peter Homberg
“We like using C-Tech battens with our grandprix and large yacht sails. The fasteners and hardware are corrosion resistant, rust free and provides easy sail care for us and our customers. The battens and hardware are engineered and make by sailors for sailors, they work perfect every time.”
Ullman Sails, IncBruce Cooper
“C-Tech has been our trusted supplier for battens and batten hardware for over ten years.”
One Palma
“We have used your product for many years and you know we call your battens a bit of a magic wand. They are a tool, but are hidden within the sail and you don’t see them. Just like there are so many bad tools out there, there are also so many bad battens. C-Tech battens are the tool that can actually make a bad sail look better, and make a good sail look great.”
