By aligning the panels (widths) at best of the direction envisaged of the efforts requesting the sail, the cut tri-optimal of sail making Elvstrom Sails allows a significant profit in versatility on a genoa sail on furler.

In the small airs, lighter, the more reactive genoa sail watch.
In the medium, its more stable profile makes it more powerful.
In the breeze, its resistance to the deformation (taken hollow) improves quality of rolling up, therefore profile. It is a profit in performance, but also in safety (aptitude to be made near).

Declined in version Offshore sport boat (associate with radial a Hydranet roving will spectra polyester) for the intensive and/or deep-sea programs of navigation, or in version Club (associate with a roving Polyester sandwich, film mylar, taffeta of protection) for the program of mixed navigation race/cruising or more simply for the skippers wishing as well as possible to exploit the potential of their boats, the tri-optimal genoa sail can in addition grow rich by many options (Return of nerve of fall by the edge, bandages UV color with the choice, correction of Eflex hollow or Zipfurl, etc...).
