The GS-F takes off into its third year. The focus of this race machine is still on absolute control and neutrality at maximum speed. The GS-F perfectly meets the special requirements of competitive and advanced foiling.

> High-Aspect Performance Foil Sail
> Developed for foil racing and foil slalom
> 3D wingsleeve for instant acceleration
> New size grading and addition of foil speed sails
> Little twist and high shape stability provide pumping efficiency
> High number of carbon tubes
> 2 clew claws on clew for optimized boom height/position adjustment

With its pronounced sail foot, shorter boom, hardly any loose leech and relatively little twist, the GS-F adapts confidently to conditions that have changed compared to fin surfing. The 3D mast sleeve with its aerodynamic precision has been revised, it releases enormous forces when pumping and gets you in the air in no time. The fast lift is supported by the high number of carbon tubes and the associated shape stability of the sail. The lightweight sail construction and special outline ensure perfect positioning in flight. Once lifted off, the sail takes over like an autopilot and allows you to put your complete concentration on the race.
Foil windsurfing is evolving rapidly and Speed foilsurfing in strong winds is becoming its own discipline. That's why our R&D team led by Renato Morlotti has re-tuned the GS-F range in size gradation and added a 5.6 and 4.5 sqm sail for speed slalom use.
The new sizes 6.7 and 7.8 sqm have got an even larger aspect ratio than their predecessors. At the same time the top area has been reduced by approx. 15%, resulting in an overall increase in control and speed. Start your engine.

We would like to point out that the GS-F series is aimed at very experienced, competition-oriented foilers. The beginner and intermediate or the dedicated foiler can also choose from our other foil sails Raise, Flylite or Bow.
