Sabfoil Sea Devil 840 Description

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 reactive foil in the SABFOIL light wind lineup. Like its larger sibling, the SD1040, it offers a dual configuration: rock-solid stability with the tail, or full freedom and maneuverability in raw mode, without it. With a smaller wingspan and quicker feedback, it’s perfect for riders looking for a more aggressive, dynamic experience.

Designed for lighter or advanced riders in active conditions

The SD840 performs best between 12 and 25 knots but can lift off earlier with the right setup. Its self-stabilizing profile and compact geometry allow tighter turns, higher speeds, and ultra-responsive transitions. The immediate acceleration under your feet makes it ideal for technical carving, sporty downwind runs, and even kite foiling.

One foil, two experiences
Tail Mode – With Stabilizer

Smooth control and stability, ideal for precise transitions and high-speed confidence.
Raw Mode – Without Stabilizer

Extreme agility, ultra-responsive handling, and a direct, surf-like feel. Built for experienced riders.

Advanced design, full carbon monocoque construction

Like the SD1040, the SD840 features a monocoque full carbon build with no fuselage, reducing drag and maximizing sensitivity. Every input translates instantly into movement, amplifying control during glides, turns, and pumping sessions.

For riders who like to push further—even when the wind doesn’t

The Sea Devil 840 is the perfect choice for those already comfortable with foiling, looking for a compact, responsive and fun setup. A true evolution tool, even in the most ordinary conditions.
