16ft Skiffs and Carbon – How did we get here?

By All News, Marine News

The first ever full carbon mast made for the 16’s was produced by CST Composites and trialled by the Bob Jane T-Mart crew. CST has been working with the 16s since our early days of carbon tube production. The 16 carbon mast prototype was made as a technology demonstrator.

The prototype 1 was based on the world champion I14 mast, adapted to suit the 16ft skiff geometry. It was made using high modulus carbon fibre and rigged with two sets of adjustable carbon spreaders.

The mast proved to be competitive out of the box with no requirement for luff round recut, placing well its first race. After numerous test sails the mast continued to perform consistently, even surviving a broken vang in 20 knots.16ft Sk

New Range Of 2011 CST 18ft Skiff Spars Is Here

By All News, Marine News

A busy lead up into the 2011 J.J Giltinan Championship saw a range of new products being released for the 18ft skiff class. The most significant probably the release of new mast sections for both no.1 and no.2 rigs as well as new rectangular booms. The development included 3D Solidworks design and in house manufacturing of new mandrels. All this was achieved in a very short time frame to allow enough on water testing in time for the championship.

The development was driven by CST’s 18ft skiff guru Chris Dixon and trailed on CST Composites 18ft Skiff skippered by Howie Hamlin. Howie finished the regatta in respectable 5th place showing the potential of the new products with minimal testing. The new masts are an evolution of last year’s design and have been developed to suit the latest sail trends and ever increasing working sail area. The result is substantial increase in stiffness over the 2010 rigs while keeping weight down to a minimum.

The new high modulus 130x55mm rectangular carbon fibre booms are also significantly stiffer than last year’s product. “Increase in mast stiffness called for stiffer booms as well, so going to a rectangular section seemed like the obvious choice. We have now done this for most of our dinghy classes as it has allowed us to maximise the stiffness in the Y axis without the added weight that would have been experienced with the oval section. Rectangular booms have been used in high performance yachts for years, so I guess it was only a matter of time before this development made its impact on the dinghy and skiff arena,” said CST’s GM, Chris Dixon.

In order to bring the weight of some of the skiffs down to minimum, CST also produced a set of intermediate modulus carbon fibre wings for the J.J.Giltinan winning boat Gotta Love It 7. 2kg weight reduction over the conventional standard modulus carbon wings was achieved, while maintaining the same stiffness characteristics.

With the next major regatta being the European Championships, we are confident that with more time on the water CST Composites 18ft skiff will be one of the hot contenders.

CST Congratulates Its New World And Australian Champions

Nine national and one world championship wins for CST product has been a result of our strong focus on R&D and a close working relationship with some of the leading sailors in their respective classes.

Our congratulation goes to the crew of “Brydens Compensation Lawyers” who bounced back to win the windy 16ft Skiff Nationals sailed from Royal Queensland Yacht Squadron. The team skippered by Lee Knapton used CST’s new carbon fibre rectangular boom, spinnaker pole and fibreglass mast tips in both no1 and no2 rigs.

Current I14 world champions Archie Massey and Dan Wilsdon convincingly won the Australian I14 Championship with a string of first places. They too used the new rectangular boom and a modified configuration HM3 CST mast.

Rohan Nosworthy and crew Neil Tasker dominated the MG14 nationals with the lowest possible score of 7, after scoring a 1st place finish in every heat. They used the newly developed high modulus elliptical mast as did last year’s winner Hugh Tait, who placed 2nd.

Trevor Fay and Nathan Chipchase once again won the Cherub nationals with the CST HM one piece mast while the B14 National Championship was won by current world champions Guy Bancroft and David Grace.

Glen Ashby added yet another Australian Championship crown to his sailing portfolio winning the A-class and Brien Hennessy won the Javelin tittle sailing with crew Andrew Hackett.

Peter V. made a comeback to the NS14 class winning the Australian Championship with Tina Babbage while Nick Craig won the Phantom class in the UK.

Nathan Outteridge was also victorious walking away with the Australian Moth Championship, sailed as a warm up event before the Worlds. He then marched on to win the World Championship as well, sailed in a strong fleet of 113 boats. In fact this was undoubtedly the best quality fleet the Moth class has ever seen. Comprising of a number of World and Olympic champions as well as celebrated Americas Cup and Volvo Ocean Race sailors.

During the past few months CST Composites worked extremely closely with Nathan to develop a range of new masts specifically designed to suit the KA and MSL10 and MSL13 sails. No less that 21 prototype masts were made for the CST Moth Team, refining the bend characteristics to perfection in order to achieve the optimum luff curve match. Nathan also used the new CST rectangular boom which has proven to be stiffer and lighter than last season’s model.

All of the above products will be available as the part of our new 2011 range in the coming weeks.

CST Carbon Tiller Extensions Used By The World’s Best

By All News, Marine News

Australian Sailing Team member Tom Slingsby has been named the 2010 ISAF Rolex World Sailor of the Year.

Tom already a multiple world champion in the Laser class is the first Australian to win this prestigious award.

CST Composites has been involved with the Australian Sailing Team since 2007 as the official equipment supplier. We decided to supply tiller extensions for Tom and the rest of the team including 49er World Champion Nathan Outteridge, in order to offer them a custom solution that would hopefully provide an edge over their opposition. Working with each team member we produced tiller extensions that are specific to their sailing style.

It is fantastic to see Australia’s best sailors achieve their goals with just a little over 18 months until the Olympics.

Nathan Outteridge Wins Moth Europeans

By All News, Marine News

In July, CST supported sailor Andrea Bonezzi was crowned the “European Contender Champion”, using CST’s HM Club mast.  Two weeks later CST spars have won yet another regatta.

This time Australia’s Olympian and CST team member Nathan Outteridge, has beaten a strong fleet of 85 boats to become the 2010 European Moth Champion..

Sailed on Switzerland’s Lake Silvaplana, the championship was one of the closest on record. Nathan and fallow CST sailor Bora Gulari were the standouts from the rest of the fleet. Last time these two met, Bora was victorious taking the World Champion crown in USA. This year Nathan came back in a new boat sporting a prototype “Elite” series mast from CST, and experienced great speed improvement to win the championship by 2 points.

The next big event on the Moth calendar is the 2011 World Championship to be sailed from Belmont 16ft Sailing Club on Nathan’s home waters of Lake Macquarie. It should be a great contest between these two sailors, however past World Champions like John Harris could also cause an upset. The top 10 is likely to be made up of ex World and Olympic Champions.

Rowing Oars Break Test

By All News, Marine News, Media

CST composites has been supplying rowing oar shafts for Jac Oars since 2007,  however we have recently undertaken more development work in order to compare CST’s filament wound tubes versus opposition fabric wrapped tubes.

A number of “cantilevered” tests was performed on both opposition and CST shafts where both deflection data and breaking loads were recorded.

The data was conclusive, it showed CST filament wound shafts to have a 25% higher ultimate load while being 11% lighter.

The secret to superiority of filament wound products lies in its high fibre to resin ratio, uncrimped fibre paths and accuracy of our computer controlled process.
