mast, boom, tube kit & battens

C-Tech spars have the highest possible stiffness and strength to weight ratios and are produced to exacting standards with consistent bend curves. This is achieved by a combination of fibre selection and placement. The fibres are all high modulus prepreg carbon fibre. These are placed with no crimp (interweaving of layers) and no laps along the the taper. This greatly improves mast strength and consistency of flex curve.



C-Tech has a range of Moth masts that can be used with all current rig and manufacturer configurations to suit all sailor weights. Standard specifications can be tweaked for individual preferences. The 04 mast range is effectively the 03 range with the reinforcing laminates shifted approximately 400mm further up the mast. This gives the mast a more even bend. The 04 model also address the issue some sailors were experiencing in certain conditions with the 03 masts blading out the sail in the head whilst not flattening in the lower half. All masts can be ordered with tall rig or deck sweeper configuration. A male mast base adapter option is also available.


Bent Boom

The latest C-Tech Bent Moth Boom supplied for boats configured with a low mast post with a 15° bend. We also have a boom with a 9° bend suitable for the old high post Mach 2 configuration. The boom is now available with the mainsheet and vang as separate fittings to suit new DS sails. The mainsheet can be placed either side of the boom kink. We also offer a single fitting where the mainsheet attachment incorporates the vang attachment with a titanium through bar.



C-Tech have developed moth PlateBatten sets with each of the main sailmakers. The battens are optimised for strength to weight with a mixture of carbon and S-Glass. The draft positions and stiffnesses have been tuned in over time to keep up with changing rig designs. All battens have the taper designed into the laminate which is cured in our autoclave and CNC cut to width. C-Tech is the Moth batten supplier to Doyle, North and Lennon Performance sails.


Tube Kit

Full tube kit, or customised tube kits available for individual requirements. A standard tube kit can consist of: - Mast post - Forward and aft bars - Outer bars (including sleeves) - Compression strut - Bowsprit - Wand


C-Tech is the manufacturer for Mackay Boats Bieker Moth vertical foils. These are an integral part of the boats international success and are made from high modulus pre-preg carbon fibre with a foam core for incredible stiffness. They are cured in our autoclave using precision alloy tooling. This process means we can achieve maximum stiffness possible for a given sectional area. This is part of the Mackay Boats Bieker Moth advantage.
