With Electra, Quantum has opted for a multi-layer system that combines performance and durability. Unlike simple laminates with only one fibre direction, Electra combines two fibre types with different tasks: The primary, load-bearing structure consists of lightweight, high-strength aramid or carbon fibres that are pre-stretched and embedded in the Electra composite. These warp fibres lie in the longitudinal direction of the fabric and carry the main loads. A tight grid of secondary X-Ply fibres made of ultra-high molecular weight polyethylene (UPE) is arranged at an angle of 60 degrees to the warp direction on both sides and, according to the manufacturer, gives the laminate long-term dimensional stability. Both fibre layers are embedded between an ultra-light, dark grey Electra film, which protects against UV radiation, salt and mechanical influences.
Dual fibre matrix and high-end optics
Quantum offers the material in two fibre combinations: Aramid for the best performance in small and medium-sized sails and carbon for maximum strength and dimensional stability in larger yachts up to 45 feet. The combination of high-performance fibres in the load direction and the UPE grid is designed to create a balanced structure that delivers consistently high performance and control in all sailing conditions. UPE is an ultra-light, low-stretch fibre, similar to Dyneema or Spectra, and is characterised by particular strength, durability and UV resistance. Unlike pure aramid sails, which are sensitive to kinks and UV radiation, the UPE grid is designed to give the Electra laminate additional robustness.
The multi-axial matrix is securely embedded between dark grey Electra film. This increases durability and protects all components from environmental influences. The result is a laminate sail that retains its profile longer than unprotected laminates. The dark, matt Electra film creates a monolithic look and gives the sails the look of high-tech Grand Prix sails.
Economical triradial design
Quantum produces sails from the Electra sail exclusively in a triradial cut and profiles them according to customer specifications. The triradial design distributes the loads better across the fibres and the cloth retains its shape even under high loads. The material is designed for mainsails and genoa sails on regatta yachts up to 45 feet. The range of applications includes up-and-down regattas as well as medium and long-distance races - wherever proven properties in terms of handling, versatility and reliability are required. The Electra sails are priced below the Fusion membrane. A triradial mainsail made from Electra-Aramid costs around 6,850 euros for an X-332 (sail area 35.8 square metres). A Fusion E5 mainsail costs around 9,484 euros. Prices vary depending on boat size, sail area, chosen fibre combination and equipment.
