Currently, Global supplies Kevlar 49 to those yachts which are suitable. The rigging is made with a PBO core which is seven times stronger than steel. Furthermore, for the large superyachts the make-up of a stay can allow intelligent rigging to be incorporated, where the core contains a measurement fibre to monitor loads.

The data is then stored in an onboard computer and regularly relayed via satellite to the factory where fatigue is tested. This can tell in advance of any problems. No stays are unnecessarily replaced and rig failure spotted in advance.

But it's not the final solution, according to MD Hugh Carpenter. "Companies are trying to put a composite rig together which uses existing end fittings to keep the customer comfortable with the aesthetics, " he told BB. "But the big issue is not the fibre/cable but the fittings and terminations, these still tend to be bulky metal fittings and might use exotic materials such as titanium, although providing an interim weight saving solution this is not a 'smart' fix".

We are working on a completely new composite rig technology with our associates in Holland and USA which will bring massive weight savings, he added.

Although we are not there yet we are supporting a programme of product testing. The look will be new and there might need to be a change in mindset of the customer and designer to accept something that looks different on the boat.
