The range of the asymmetrical spis of cruising Elvstrom Sails is declined around a cut tri-optimal. By reorientating each panel (width) in the pin of the effort to which it will be subjected, the spi offers a stability of profile maximum.

The purpose of this characteristic is to return your spi more comfortable (less rhythmic rolling, starting power supply generator to the windward side etc...) and more general-purpose (better aptitude to be gone back to the wind).

Their forms, directly inspired of the experience gained in regatta, mets the accent on the facility and the stability of adjustment. This effect is obtained in particular by full and round cambers of attack.

The grammage of roving evolves/moves between 1.1 (45 gr/m2) and 1.5 (65 gr/m2) according to the size and the program of the boat.

The general completions are proposed according to the Coastal standard (pleasure use) or Offshore sport boat (intensive and/or deep-sea navigations) as well as possible to adapt to the exigeances owners.

However, whatever the version of completion, all the asymmetrical spis Elvstrom Sails are equipped with a nerve with guindant intended to take again the tension of guindant with the loose one.

This completion, while making it possible to tend effectively guindant it without deforming the roving (the nerve in rope fine polyester taking again the tension) makes it possible to go back much more effectively to the wind generally, and particularly in small time.
