KSD780-FCM-370-85/BB - Sea Devil 780-FCM-370-85 Blackbird Glider - Modular Backtail

The Sea Devil DNA, evolved with Blackbird technology

The Sea Devil 780 Blackbird was created to bring the iconic feel of the Sea Devil family into the new Blackbird architecture: more modular, more evolved, and more customizable.

It is a front wing designed for riders looking for a foil that feels reactive, playful, and precise through carves, while still maintaining efficiency, control, and stability as speed increases.

The result is a surf-oriented feeling, ideal for drawing powerful lines, moving quickly from rail to rail, and keeping rhythm between one wave section and the next.

Smooth carving, immediate response

The delta shape of the Sea Devil 780 Blackbird delivers exceptional maneuverability through turns. Its profile concentrates more volume in the central area of the wing and gradually reduces it toward the tips, creating a stable feel underfoot while remaining free and reactive when loaded laterally.

This distribution makes the wing feel natural on turn entry, solid through the carve, and fast on exit, inviting the rider to push harder, tighten the line, and change direction with fluidity.

Stability at speed, without losing playfulness

The integrated winglets help maintain control and stability as the foil accelerates, especially when the rider is setting up for a carve or entering a faster section of the wave.

The feeling is that of a foil that is always ready to react, yet never nervous when speed increases: playful from rail to rail, precise through turns, and efficient when pumping back to the lineup or linking multiple sections.

The advantages of the Blackbird system

Thanks to its Blackbird construction, the Sea Devil 780 becomes part of a fully modular system, compatible with the new S, M, and L full-carbon fuselages and with the full range of Kraken stabilizers or Blackbird integrated stabs.

This allows the setup to be customized according to riding style, conditions, and desired feel: more reactive and radical with shorter fuselages, more stable and progressive with longer fuselages.

Recommended for

The Sea Devil 780 Blackbird is designed for riders who want a surf-oriented, dynamic, and precise foil, with a strong focus on carving and rail-to-rail transitions.

It is ideal for riders looking for:

• smooth and aggressive carving

• playful rail-to-rail feeling

• stability as speed increases

• efficient pumping back to the lineup

• modularity with full-carbon fuselages and Kraken stabilizers

• the Sea Devil DNA with all the advantages of the Blackbird system

Note on RAW mode

On this model, RAW mode without stabilizer is not available, because the front wing size does not allow the foil to be self-stable.

However, with the right combination of fuselage and Kraken stabilizer, the feeling remains close to the Sea Devil sensations riders are used to: free, surfy, direct, and very natural underfoot.
