PWA Slalom Design
The PWA permits racers to use just one foil board size. To meet this challenge, both sizes from the RF V4 range have been shaped to handle the full spectrum of PWA Foil Slalom conditions.

Top Speed & Control
The RF V4’s sleek aerodynamic design, paired with its reduced volume and lighter weight, is tuned to minimize the gap between the speed you can achieve and the speed you can comfortably control through the extended flight.

Wind Range
Each board in the range is tuned for its ideal wind range, giving you the confidence to race in every condition, from moderate breezes to full-power days.
Carbon ConstructionCarbon Construction allows the creation of the lightest designs possible. The inherent strength of carbon fibers means we can use less material compared to the fiberglass variant while still achieving exceptional durability. Carbon also enhances stiffness and responsiveness in the board, making it an ideal choice to seamlessly blend top-notch performance with minimal weight.

Description
RF V4
Slalom & Racing Foil
Speed changes everything.
The moment your foil lifts, the water falls away. Drag vanishes. The horizon rushes toward you. But here's what most riders discover too late: raw foil speed means nothing if you can't hold it.
The RF V4 exists to close that gap.
We've stripped away everything that creates resistance between intention and execution. The aerodynamic deck slices through airflow rather than fighting it. Thin front rails and a domed top reduce turbulence at the speeds where turbulence matters most. The result is a board that lets you reach velocities you previously glimpsed only in brief, white-knuckled moments.
Two dedicated shapes — 75 and 85 litres — share a philosophy refined through seasons of PWA competition. Reduced volume and carefully positioned rail geometry help the tail sink cleanly, engaging your foil with near-instant response. Twin parallel cut-outs at the rear boost momentum during take-off and minimise drag when you inevitably touch down.
Control comes from connection. A wide tail with adjustable footstrap positions gives you the leverage to fine-tune foil pitch, whether you're driving upwind or running deep. Carbon construction keeps weight low without sacrificing the stiffness that transmits every subtle input directly to the foil.
The PWA permits racers just one foil board size across all conditions. Both the RF V4 75 and 85 have been shaped to handle the full spectrum of Foil Slalom racing — from marginal breezes to full-power blasting. One board. Every condition. No compromises.
High-speed foil performance. Designed for those ready to use it.
High Speed
While the hydrofoil drives top-end velocity, it's the synergy between board and sail that determines whether that speed can be reached — and maintained. The RF V4's sleek profile, reduced volume, and lighter weight are tuned to minimise the gap between the speed you can achieve and the speed you can comfortably control through extended flight.
Competitive Design
PWA regulations permit racers to use just one foil board size. To meet this challenge, both the RF V4 75 and 85 have been shaped to handle the full spectrum of Foil Slalom conditions — making them equally at home in light airs and high winds.
