SiFly V3 hydrofoil adds adjustable fuselage and interchangeable propulsion

SiFly is changing the ride, not just the trim. The Hydrofoil V3 arrives with an adjustable fuselage and interchangeable propulsion, a shift that gives riders one platform that can be set up for stability, learning, carving, or a more aggressive surf feel without moving to a different board.

The centerpiece is the modular drive system. SiFly says the V3 can run with a Jet Drive or a Prop Drive, and the company draws a sharp line between the two: the Jet Drive is meant to deliver maximum safety and a silky smooth ride, while the Prop Drive is built for performance and agility. That split matters for active riders because it changes the way the board fits different sessions, from first rides and family use to faster, sharper turns for more experienced foilers.

The other major change is the Dynamic Rail System, which lets the rear stabilizer slide. In practical terms, SiFly says that gives the foil a wider tuning range, calmer and more forgiving for newer users, or more nimble when riders want a sharper response. The V3 also includes an option for a beginner-friendly auxiliary stabilizer, another sign that this is being built as a system riders can grow into instead of outgrowing quickly.

Under the hood, the V3 carries 8 kW of power and a shorter fuselage, both aimed at making the board feel more responsive and reducing the sense of distance between rider and drive system. SiFly also says the mast profile is sleeker, which it says cuts drag, noise, and ventilation. Taken together, those changes point to a package that is about more than raw speed. The architecture is designed to alter how the foil behaves in the water and how easy it is to live with on land, especially for schools, rentals, and progressing riders who need one board to cover multiple skill levels.

SiFly says riders can move among Sport, Intermediate, and Comfort modes, and the company is leaning hard into modular design across the lineup. The V3 is manufactured in the European Union and carries a 2-year warranty, details that add to its case as a platform meant to be used, swapped, and kept in service. For SiFly, the V3 is not a cosmetic update. It is a reset of the upgrade logic itself.
