The range of the 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.
