windsurfing44 (très bon site également ) signale une très intéressante interview de Peter Munzling sur le site windsurfing.nl :
https://www.windsurfing.nl/index.php/top-nieuws/1838-interview-peter-munzlinger-sail-designer-ga-sails

Avec de très bonnes questions :
- Raisons pour le changement de courbure de mât de hard top à CC
- Est-ce qu'une marque comme GA intègre une durée de vie supérieure à 1 ans pour les voiles de course
- Raison et décision sur le placement des lattes sur la voile de race ?
...

Pour une fois des vraies questions - bravo

FORMULA / SLALOM

VAPOR 2017
EFFICIENT DIRECT LIGHTER


With the 2016 Vapor we had our most succesful season in the PWA slalom in recent years. Ross Williams did his first podium in the final Slalom ranking and archived the best result of his carrier, the same did Taty Frans finishing 6th, placing two Ga Vapors in the top 10 of the most hard fought windsurfing competition series in the world.

Also the rest of the team placed great, with Cedric, Sebastian, Ben and Antoine all in the top 20 and Ethan Westera becoming Youth World Champion.
For the 2017 model we focused on improving this race-winning design even more. We improved the low end performance to create a more powerfull Vapor.
We divided the range in 3 size groups: the two bigger sizes 9,3 and 9,6, most light wind oriented, the central sizes 8,6 to 7,1 more allround oriented, and the 6,4 and smaller sails more high wind oriented.
We found that the new foot geometry and the outline with no cross batten concept worked best for the 2 biggest sizes, while for all the other sizes the Cross batten still had an edge.
We greatly increased the width of the mastsleeve and the volume in the front part of the sail by increasing the shape in the triple internal luff panels, both in the bottom and also higher up with . With that we drastically incredted the drag of the sail. The sleeve width proportionally reduces as the sail size decreases. We worked on having a more connected leech twist so to not loose any little piece of wind energy. The rotation of the cambers is also much smoother and the acceleration out of the jibe is amazing.

We opted for a small camber at the foot batten to help for this, while the two central big ones and the top small one remain the same, sizes 6.4 and below are exclusively equipped with the smaller camber. The top 4 batten pockets are integrated inside the panel overlap for a more simmetric, efficient, direct and lighter construction.

A simplified panel layout with less panels and seams drastically reduces the overall weight.



New for 2017:

All new constant curve luff curve
New high-aspect-outline
New removable Cam creating an broader tuning range
Improved POSI-LEECH with new dynamic cut-out for more power and agility.
Inset clew geometry for reduced boom length
New Integrated-Batten-Technology improves efficiency, response and rig weight
New Lightweight performance panel-layout for a maximum strength to weight ratio

En français seul les 9,6 et 9,3 ont la latte qui ne croise pas le Wish, les autres tailles, 8,6 et en dessous garde la cross batten classique !

A plus,

Yann
