Quantum® J/111 Sails: Designed for Performance

Quantum’s J/111 sails were developed with a single goal: to develop leading-edge sails offering the very best performance. Quantum® sail designers Kerry Klingler and Doug Stewart collaborated on the designs using iQ Technology® to define the sail geometry and complete the aerodynamic and structural analyses.

The J/111 class rules specify two jibs plus one #4 heavy-weather jib to be set on a roller furler. Fast headsail changes are another requirement. These factors led to the use of roller battens. The advantage of roller battens is that when the sail comes down, the battens easily fold into a genoa turtle without having to be removed. They also support the leech better than vertical battens.

The Asymmetrical spinnakers are based on design work done for the Megles 32 class. Our sails are state--of-the-art in the M32 class and the sizes are close to J/111. We redesigned the sails to meet the geometry of the J/111 rig and sized them properly for the class rules. Slight tweaks were made for the aspect ratio and boat speed differences. In testing, the R2 and R3 asymmetricals were fast and easy to trim.

The mainsail was designed for versatility and provides great performance in a wide range of conditions. On-the-water-testing led to a couple small adjustments resulting in an ideal sail shape.
 
Quantum’s new J/111 sails were evaluated with side-by-side and race testing, the results of which can be found in our tuning worksheet available for download here.  Look for Quantum’s new J/111 sails on the water. They are super sails, well-shaped with a good fit and great performance —all made possible using the best design tools, the most advanced membrane sail building process and the talents of a dedicated team.
