According to F4, extensive software calculations were initially carried out during the development of the GP foil in order to create a design with the lowest possible drag and high lift. "The result of this process is a series of super-thin and less turbulence-generating profiles for all components of the platform," says F4. The international and national team riders then spent a year further developing the GP series components.
Features of the GP line include a panelled connection between the mast and fuselage. "This design virtually eliminates all turbulence and interference, yet remains ultra-stiff and provides a super smooth and supple feel that you notice immediately when you get on the foil. It's faster, planes better and turns smoother than anything you've experienced before," the developers enthuse.
Three parts, five screws, and the foil is ready
The wings are connected to the fuselage via the first fully hardened and panelled construction, according to F4. The profile now consists of just three parts: Mast, front wing and back wing with integrated fuselage. By dispensing with the aluminium hull, the weight has been reduced and the risk of galvanic corrosion eliminated. The entire platform is joined together with just five screws. F4: "This innovation drastically improves performance, reduces drag and simplifies foil assembly."
Ultra-high modulus carbon is used in all components of the series, which is intended to be particularly stiff: "When you get into the 40-knot range, you need all the stiffness you can get, and the GP platform offers exactly that." The mast and wings each come in two technologies, while the wings of the TI version have a titanium core.
