Description
The Cabrinha Tweaker Fuselage is the foundation of the Tweaker system, designed to give riders complete control over the feel, balance and performance of their Union foil setup. Available in both 340mm and 390mm lengths, it allows you to tailor manoeuvrability, stability and control to your riding style and the conditions of the day.
Built from premium M40 prepreg carbon construction and supplied with the Tweaker Shim Kit, the fuselage unlocks precise stabilizer tuning in 0.5° increments so you can fine tune lift, pitch sensitivity, front-foot pressure and overall ride feel.

WHO IS IT FOR?
The Tweaker Fuselage is designed for riders who want to personalise their foil setup rather than accept a fixed geometry. It is ideal for intermediate and advanced wing foilers, prone riders and downwind enthusiasts who want to tune stability, turning behaviour, lift and speed to suit their riding style.
340MM VS 390MM – WHICH SHOULD YOU CHOOSE?
| Fuselage | Recommended For | Ride Characteristics |
| 340mm | Parawing, prone and carving-focused riders | Fast turning, loose feel, maximum manoeuvrability |
| 390mm | Wing foiling, freeride progression and downwind riding | Greater stability, smoother pitch control and confidence at speed |
INCLUDED TWEAKER SHIM KIT
Every Tweaker Fuselage includes the complete Tweaker Shim Kit and installation tool. Riders can adjust stabilizer angle in precise 0.5° increments to fine tune:
- Lift and take-off characteristics

The ability to adapt your foil to changing conditions is what makes the Tweaker system unique within the Cabrinha Union ecosystem.
