Sailboat carbon mast
20-60 ft YACHTS CST Composites

CST Composites manufacture a range of mast sections, available in standard modulus (SM), intermediate modulus (IM) and high modulus carbon fibre (HM). These can be supplied with any wall thickness requirement and fibre orientation.
A list of standard CST mast sizes is displayed below, however we have a range of smaller sections typically used for dinghies as well. We can also produce custom and one off spars engineered specifically to suit the boat you sail.
Furthermore, If you requie a mast outside our standard range, we can machine custom mandrels and tooling for the job.
