RACE SMOOTH:
INTEGRATED WING TO FUSELAGE CONNECTION

 

An upgrade on regular bolt-on-wing connections, F4 Racing Foil integrates the wing and fuselage together creating unparalleled stability and improved hydro-dynamics.
The integrated design ensures that the critical leading edge of the front wing creates undisturbed flow, meaning improved lift-to-drag ratio, and faster speeds.

RACE PRECISE: PROGRESSIVELY TAPERED MAST TO BOARD CONNECTION

 

Progressively tapered in the area flying above the water, this newly refined mast improves strength and rigidity where it is needed most: just below theTuttle box. Additionally, the tapered shape creates a step on the mast that sits on the underside of the board and prevents the foil from moving, thus ensuring an ultra precise angle position for board and rider.

RACE SOLID:
STAINLESS CLAMPING TAIL SYSTEM

 

Innovatively engineered, F4 Racing Foil eliminates the classic bolt-on tail in favor of a more seamless design that blends the fuselage into the tail wing. This connection technique further reduces drag, enables precise angle tail adjustment and is rock solid.

RACE CONNECTED

 

Unique to F4 Racing Foil, the elliptical mast progressively tapers from its thinner edge to thicker core, eliminating weakness at the critical stress point on the front edge where the down-force hits the foil.
To connect fuselage to mast, we engineered a system using 3 stainless steel bolts molded into the carbon fibre.This design offers the most effective load transfer between mast and fuselage by eliminating the typical straight-edge, and also provides a stronger mast-to-fuselage connection compared to standard drilled carbon and cross-dowel system.
