Whether you're an intermediate rider seeking progression or an expert pushing the limits, this setup delivers tons of fun.
Two souls, one vision. Precision and speed in every condition.
Discover new lines—where others see limits.
The Sea Devil 840 is the most compact and responsive foil in SABFOIL’s light wind range. Just like the SD1040, it features a dual configuration system: rock-solid control with the tail, wild and agile without. With a smaller wingspan and ultra-fast reaction time, it’s built for riders who want control, speed, and pure fun in a more aggressive format.
Engineered for lighter riders and active conditions
Optimized for 12 to 25 knots, the SD840 offers lift even in lower winds with the right wing setup. Its compact, self-stabilizing profile supports tighter turns, faster acceleration, and effortless pumping. It’s also ideal for kite foil with small kites, offering unmatched maneuverability.
One foil, two experiences
Tail Mode – With Stabilizer
Smooth control and directional stability—ideal for progression and controlled lines.
Raw Mode – Without Stabilizer
Explosive carving, quick transitions, surf-like responsiveness. For experienced riders seeking freedom.
High-tech construction, no compromises
The full carbon monocoque design—no fuselage—keeps drag low and feedback high. The foil becomes an extension of your body: intuitive, fast, and precise. The included Kraken mast guarantees rigidity and compatibility.
Ready to ride. Built to evolve.
With the SD840 and Kraken 83 mast in one box, this set gives you an agile, high-performance platform to elevate your sessions in any light to moderate wind condition.
When you ride the edge of control, you're just beginning to explore.
