Fittings

Having similar dimensions to the new alloy sections means that we will be able to use the same heel fitting and deck ring for both aluminium and carbon masts. Insulation on these items is not a problem using e-glass or mylar tapes.The external sail track incorporates a central boltrope groove.

Plant

The new UK factory has a 20m autoclave at it’s heart, and the current filament winding machine has been extended to match. They will allow one piece sections to be made up to 19.3m long.Above this length sections can be joined. Special joining sleeves have been developed that minimise weight and have a neglible effect on local stiffness. How much extra will they cost? Can they be tapered? As the carbon mast can be optimised, direct cost comparisons are difficult. Our selling prices are very competitive in the market, especially for the given performance. There are standard parabolic tapers for fractional rigs. Each reduces the section f&a dimension by 33%. Do holes weaken the structure? Can it be painted?

COMMONLY ASKED QUESTIONS

Yes. Holes may only be cut where the mast is suitably reinforced and should be fitted by a person with experience in composite materials. Yes and yacht spars are painted with clear U/V marine varnish as standard. How difficult is it to repair? Not difficult. The repair must be done by a person skilled in composites. Can extras be added? Yes. But reinforcement is required. Additional reinforcement may be added after manufacture, but the best method is to include extra reinforcement when the tube is made.
