HydroFoil Slalom

Compared to fin racing, foiling is more than just competitive: Already in the first year of PWA competitions, foil boards predominantly led the rankings. Today, they are ahead in all areas of slalom racing – unless there are limitations and restriction by regulations and rules.
In 2024 the PWA will only allow one size of foil board in a racers quiver. So, our main sizes had to remain on top of the game and were newly developed as Werner Gnigler shaped three new boards to cover all PWA Slalom conditions. This way every rider can find his best performing board depending on his weight and the conditions he will use it in.
The unchanged 91 is still up-to-date in covering the light wind side of foiling and will be used in national light wind events, while the proven 78 still covers the high wind segment and long distance events like the famous DEFI Wind.

Here are the essential shape news:

• Aerodynamic Nose Area Efficiency
The boards fly through the air, so, minimizing air resistance results in improved control and speed. The main target was to achieve maximum efficiency with the following refined shape details: We flattened the nose scoop and made the front rail thinner. To optimize the airflow we introduced a slightly domed deck in that area, too. All HydroFoil Slalom boards are very short, minimizing swing weight and improving top end control.

• Mast Base Area
The rails in this area are fuller with a hard, sharp edges – the most efficient shape to create lift to get into flight mode and to drastically reduce drag on touch downs for instant re-bounce.

• Deck Shape: recess for the deck box
This deep recess lowers the pivot point of the mast base which helps closing the gap between the board and sail foot. It also provides efficiency and additional control when pushing the limits and during the gybe.

• Deck Shape: stance and power
The deck shape in the standing area received the most radical change: It is flatter now and the pads extend even a bit further than the maximum width of the rail. Now, the rider can move the foot into the ideal position without changing the angle of leverage towards the foil which may happen on rounded rails. This also allows to have two strap plugs for the rear foot – the inboard one for high wind runs and reaching, the outboard one for tighter reaches and light wind.

• Deck Shape: tail aerodynamics
The tail now comes with a concave recess, almost like a cut-out, channelling the air flow along the deck and supporting the rider with additional control since the smoother and more directional airflow stabilizes the board in the air.

• Large Tail Cut-Outs
When foiling, the cut-outs have two main functions: To reduce the volume in the tail and to reduce drag.
The reduced tail volume allows the rider to sink the tail when pumping to loading up the foil for instant take-off.
All boards feature cut-outs, individually shaped for the intended range of use of each board. On occasional touchdowns, the deep cut-outs significantly reduce the wetted area resulting in less drag – which is imperative and vital as riders sail and touch-down at much higher speeds.

• Wide Tail
The tail provides lots of leverage over the foil which is a key factor for going fast and still remaining in control despite all these enormous forces. It is essential when trying to find the best compromise between a comfortable stance and efficient power distribution towards the foil.

TECH FEATURES
* Full Biax/Carbon Deck
