CST Composites is the official International B14 Class supplier; CST supplies a complete range of carbon tubing for masts, spreaders and wings for the B14 class.

Our 50 series masts are made using intermediate modulus carbon fibre and have been developed with the leading class sailors to offer the optimum bend characteristics. CST has also developed new carbon fibre wings replacing the existing aluminium variety. These are available as cut to length tubes ready for assembly, or as a complete wing kit including moulded carbon joints and acetal fittings.
