Aluula says fabric validated on Charal Transat race win

Executive Summary

• Aluula Composites Inc. successfully validated its patented ultra-light composite fabric in elite offshore racing, powering the winning spinnaker on the IMOCA 60 yacht Charal at the Transat Café L'Or regatta.
• The Aluula spinnaker demonstrated superior performance compared to conventional materials, offering significantly reduced weight, increased stiffness, and enhanced tear resistance, which translated to improved speed and stability during the race.
• This validation reinforces Aluula's strategy as a next-generation fabric supplier for high-performance marine and windsports applications, leveraging its no-sew, adhesive-free composite technology.

Key Details

• Race Performance: The IMOCA 60 Charal won the Transat Café L'Or regatta after 11 days, 19 hours, and 45 minutes at sea, covering 5,467 miles at an average speed of 19.3 knots.
• Material Advantages: The Aluula spinnaker is significantly lighter, three times stiffer, and 10 to 20 times more tear-resistant than conventional polyester and nylon IMOCA spinnakers.
• On-Water Validation: The fabric's stiffness and stability in dynamic downwind conditions were proven, resulting in reduced pitching, more stable foiling, and direct conversion of wind gusts into speed.
• Technical Specifications: Patented UHMWPE high-performance composite fabrics are eight times stronger than steel for equivalent weight and are recycle-ready.
• Construction Method: Utilizes no-sew, adhesive-free techniques that enable welding of panels and junctions, eliminating traditional stitched weak points and allowing for highly precise panel geometry.
• Strategic Partnership: Developed in collaboration with North Sails France and the Charal IMOCA team as part of an evaluation for next-generation materials for performance monohull foiling offshore racing yachts.
• Market Expansion: Validates Aluula's premium alternative to traditional sailcloths and supports growth in windsports and other marine applications, such as towing kite systems for cargo vessels.

Notable Quotes

• Bertrand Pace (Sail Development Lead, Charal Team): "A classic spinnaker ... the gust pushes to leeward. But with the Aluula, the luff stayed very stable. The gust becomes speed right away. The result was a very clean and very efficient sail."
• Sage Berryman (CEO & President, Aluula): "Offshore racing exposes materials and construction to demanding pressures. This project demonstrates how our next-generation composite fabrics can fundamentally change how sails can perform, not just incrementally improve them."
