GP Sails Sonata Class Mainsail

GP Sails Supplied Sonata Class Mainsail

Built for performance, control, and longevity, the GP Sails Sonata Class Mainsail is a premium upgrade for serious sailors looking to maximise speed while maintaining balance and ease of handling.

Crafted from 100% Contender Sailcloth Polypreg High Aspect 5.52, this sail combines durability with excellent shape retention, ensuring consistent performance across a wide wind range.

Precision Design & Construction

This modern cross-cut sail features a rocked panel layout, carefully engineered to align fibre orientation with load paths along the leech. The result is a smoother, more efficient foil shape that delivers:

• Reduced heel angle
• Less weather helm
• Improved upwind efficiency
• Greater overall control and safety

Panels are bonded using a hybrid glue and triple-step anti-chafe stitching system, reinforced with radial corner patches to evenly distribute loads and extend sail life.

Premium Hardware & Finish

Attention to detail sets this sail apart. All key load points feature stainless steel rings or Rutgerson press rings at the head, tack, clew, and reef points—ensuring strength where it matters most.
