Avanti Sails Tempest V2 Diaphragm 2023

Membrane Technology

We started with our own exclusive, ultra-light membrane construction. Proven, copied and ranked, our membrane is engineered to distribute loads evenly and appropriately throughout the sail skin in a way that traditional paneled sails cannot replicate. We call this Smart Load Technology; fiber and strength where you need it, weight savings where you don't.

Features

- Seven battens. With a deduction in battens, this new skeleton is lighter, easier to rotate, and more agile.

- No Sock Center Seam. Our single piece leading edge sock panel with no center sock seam reduces turbulence and adds durability.

- Flow aligned Battens. The new Streamlined Design features a fanned batten layout. This new batten layout reduces drag and increases acceleration, while maintaining the stability of a more traditional cross batten position.

- Twist Dynamics. Each sails size has an upgrade the overall twist profile. The scooped twist flow works in harmony with the skeleton to give the sails and easy breathing feel over a tremendous wind range.

- Foot Batten Particulars. To improve rotation of the sail, foot cup has been slightly reduced to allow easier sail body rotation. Rather than kicked up, the foot and cross batten angles remain standard. Keeping this orientation, slightly more perpendicular to the foot edge, adds stability and reduces foot perimeter bounce in chop.

- Head Loading. Improved string mapping keeps the sail head under constant load ensuring the twist and drive of the sail is always under control and in place.

- High Aspect. New higher aspect ratio reduces back hand pressure, making the sail the perfect candidate for high end foil racing.

Performance membrane

Avanti laminated load-path membranes differentiate themselves with increased durability, weight savings, and superior performance. These sail skins are unparalleled in the market today. Each panel is custom engineered to align high-end Aramid fibers along primary load patterns. Nobody does this better. Where polyester film sails tend to stretch when powered, our aramid membranes carry loads from corner to corner, radically reducing distortion under load. Saving weight and limiting stretch are key to maintaining sail performance over a wider wind spectrum. The result is pure performance which one feels immediately on the water.
