This company’s mission statement is exciting: make cool things go fast. When you
look at the list of jobs this composite engineering company has done it is clear they
practice what they preach.

Alex Vallings and Lyn Holland started C-Tech in 1997 through a shared passion for
sailing. Alex originally made carbon components for small yachts from a converted
home shed in West Auckland. Using products he made for the 12ft Skiffs he was
racing, Alex was able to test out areas of improvement. As his boat continued to
win races, other competitors were keen to get hold of carbon spars for their boats.
And so C-Tech, a composite manufacturing company, was born. Over time,
Alex continued to expand his knowledge and the variety of components made by
C-Tech grew...

C-Tech's 5 Axis CNC Router is Now Operational

C-Tech is always looking to grow capabilities and stay at the cutting edge of technology delivering premium products to its customers. We have recently added new infrastructure to complement our extensive range of dedicated laminating machines, plotter, world class clean rooms, ovens and autoclave.

C-Techs 5 axis Routech R200 CNC Router-291
C-Tech’s 5 axis Routech R200 CNC router is now operational in its purpose built room.
Installed in a purpose-built room, the Routech R200 5 Axis CNC router has a machining envelope of 5,300mm x 1,370mm x 800mm.  C-Tech are now able to machine foam cores, moulds, jigs, prototypes, 2D sheets and complete post production processing in-house. The CNC machine has filled a gap in our manufacturing assets and enables C-Tech to tackle more challenging and complex projects. C-Tech is now able to see most composite projects from tooling through to the final fitted-out parts. 

Router Head-565-245 Tool for Lifting Dagger Board-647-482
Tooling for lifting dagger boards machined using a 5 axis CNC Router.

Although the machine has only been operational a few months, it is already busy and integrated into the processes for masts, battens and tubes ensuring accurate machining of parts for tooling and fit-out. It is improving lead times and efficiency in the workshop keeping staff and customers happy. 
The main materials being machined are composites, plastics, timber and tooling board, however, depending on the project the machine is capable of working with a variety of other materials.

Eastman Plotter-212
In combination with the Eastman S125 plotter and autoclave it completes the ideal set-up for processing premium composite components in-house.

The 5 axis CNC router completes the start to finish process at C-Tech for complex female moulded parts cured in the autoclave.

With new technology comes capable new staff to keep C-Tech performing at it’s best, and we have just made two key appointments. Sam Bullock joined C-Tech in May to run the 5 Axis CNC router. Sam is New Zealand’s top kite foil racer and has an impressive sailing CV. After completing his Mechanical Engineering degree he worked at Styrotech gaining experience on machining, moulding and materials and adds a boost to C-Tech’s capabilities.

Sam Bullock-874 Thomas Mellano-135
Sam Bullock and Thomas Mellano.

Thomas Mellano also joined C-Tech as design manager in May. After completing his mechanical engineering degree Thomas worked at Karver in the early days helping develop their product range. He then spent a number of years at Safran in the aerospace and composite divisions working on process development, quality control and product design for business jets. He has returned to a smaller (non-corporate) company to follow his true passion in the marine industry. Thomas brings experience and skills from the aerospace industry to our production processes, engineering capability and 3D modelling.

2017 OK Dinghy World Championships

Congratulations to Nick Craig who dominated the recent 2017 OK World Championships in Barbados using a C-Tech mast. Nick was quick with no result outside of the top 3 and six race wins. With changeable wind strength and a confused sea state Nick had the power he needed to get out at the start and power away from competition both upwind and downwind. Final results here.

2017 Moth Worlds - Moth Speed Uncovered

With the 2017 Moth world championship starting Tuesday, C-Tech’s Tim Willetts takes time to reflect on changes in Moth class rig design and development over the past six years. A lot has happened behind the scenes that is giving the top sailors the edge by staying ahead.
Software analysis of a higher position on the Moth rig 500
There have been two clear periods of development where ideas were explored and the performance of the class improved. Willetts who is passionate about the Moth says it is a unique and exciting development class to work with. 
‘Because the Moth is so sensitive to weight and small design changes, it has been an excellent opportunity to work with the world’s best and learn. The class enables a fast turnaround between new ideas, design and testing which has accelerated progression’ This fast paced environment has kept the Moth at the forefront of international dinghy development, and it remains one of the highest performing classes on foils.... continue reading here.

C-Tech helps Emirates Team New Zealand get to Bermuda

C-Tech is proud to have been involved with Emirates Team New Zealand for yet another cup campaign.

It has been a 15 year long partnership since C-Tech and Emirates Team New Zealand first worked together during their 2003 campaign to supply sail battens. Despite radical changes in the boats themselves, C-Tech continues to supply top-end carbon components to the high-tech foiling race yachts. C-Tech has now supplied the team with wing components, rudders, dagger board cases, fairings, lifting posts, tiller extensions, accumulator tubes, struts, prods and ‘bike components’ for their 2017 challenge. 

C-Techs’ managing director Alex Vallings has been working with the Team since day one.  “C-Tech is delighted to be working with Emirates Team New Zealand” says Vallings. “Over the last 5 campaigns we have seen a massive change in technology - foiling has turned sailing on its head.  There has been a huge amount of learning needed from the teams, which has given us a fantastic opportunity to learn with them, and keep abreast of the latest developments and manufacturing techniques.” 

Emirates Team New Zealand Shore Manager Sean Regan commented “C-Tech have taken on a key role building specialised componentry as part of the build group for our current AC class yacht. The team at C-Tech ensures the constant last minute changes to design and construction are communicated, planned and implemented efficiently to ensure the parts are completed on time and quality controls remain at the highest standard”

The staff at C-Tech enjoys working with Emirates Team New Zealand, and wish them all the best in Bermuda.

Go the Kiwis!

C-Tech are Proud Suppliers to the Q23

Q23 Garda1-81
C-Tech are proud rig suppliers for the Q23 foiling production sports boat. We have worked together with Quant Boats to come up with a rig solution that can handle the high loads generated by the unique DSS foiling configuration. We are just finishing off a set of 10 production rigs. The Q23 is a truly innovative project that has succeeded in delivering a versatile foiling boat that is easy enough for amateurs to step on and experience high speed foiling. The boat was recently announced winner of the ‘European Yacht of the Year’ award. The Q23 is able to ‘fly’ at 20 knots boat speed in just 6 knots of true wind speed. The current speed record is a thrilling 27 knots.
Tim Willetts of C-Tech says "It has been a pleasure to work with the brains behind this project - Hugh Welbourn and Michi Aeppli. There are few people with more passion for their product in the industry than Michi". C-Tech wishes happy foiling and maximum enjoyment to all the new Q23 owners.
See more about the Q23 at www.quant-boats.com.

Full Carbon J-Foils

C-Tech has recently completed a set of J-foils for an SL33 using a new construction method. Utilising previous experience gained from Americas Cup foil projects we developed a full composite elbow join.
Previous J foils had been manufactured with a metal elbow to join the main shaft to the lifting surface. This was to overcome high loading in this area. Metal elbows alone can be up to 40kg if there is a large radius in the design.
C-Tech developed a method that would make a full composite foil possible. An elbow was tested to verify the construction method and the results exceeded all expectations. It was in fact the testing jig that failed at a load double of what the designers were expecting.

The finished J -foils weigh 34.5 kg and are stronger, lighter and stiffer than superseded set.  The key to the success of this project has been in developing a cost-effective manufacturing method that enables the right mix of off-axis fibre in the elbow that has been consolidated by autoclave pressure.

Debrief on 2015 Moth Worlds

Rashley 2In one of the most competitive fleets the C-Tech rigs performed well with two in the top 5 (Chris Rashley 4th, Chris Draper 5th). It was however a tough regatta for two of our sponsored sailors, Scott Babbage and Chris Rashley.
Scott and Chris were both using C-Tech masts, battens and tubes on their Moths.
Chris suffered from a protruding disc in his back during the build up in Australia, yet miraculously recovered to finish 4th overall. Read his take on the worlds here.
Scott Babbage had blistering pace upwind taking some race wins but a crash in race 9 saw him have to carry a DNC pushing him outside of the top 5.
The development program has already begun for 2016 with some innovative ideas being worked on.
