Revolutionary SailGP F50 Catamarans Soar Above the Water
The SailGP, a thrilling and action-packed racing event, has taken the world by storm since its debut in 2019. At the heart of this high-speed spectacle are the F50 catamarans, boats that defy traditional sailing norms by floating at speeds of up to one meter above the water thanks to their innovative hydrofoil technology [1][4].
These state-of-the-art vessels boast a 29-meter high, airplane-like wing sail and a nine-meter-wide double hull [2]. The hydrofoils, inconspicuous beneath the surface, are instrumental in the F50s' extraordinary performance.
The hydrofoils' primary function is to lift and stabilize the hulls above the water, reducing the resistance that usually slows boats down. A dedicated flight controller continuously adjusts the foils’ angle and position via a complex control system to maintain a stable flight height, critical for maximizing speed and avoiding stalls [1].
By reducing drag, the boats avoid the massive forces associated with hull-water interaction. This shift from displacement sailing to foil-borne racing is the main reason behind their exceptional velocity [3][4].
Moreover, the hydrofoils' precise, rapid control allows the crew to respond swiftly to changes in wind and course conditions, resulting in enhanced maneuverability. This control is supported by advanced telemetry and onboard computational analysis of performance data [1][3].
The F50 catamarans' aerodynamic wing sail complements the hydrofoils, generating huge aerodynamic forces that enable the boat to harness wind power more efficiently and maintain lift-off speeds [3].
This hydrofoil technology transforms the F50s into highly responsive, high-speed "flying" machines, pushing sailing performance far beyond conventional limits [1][3][4]. However, if the boat becomes too slow, it falls off the foils.
Sailing an F50 catamaran requires finely tuned teamwork. The wing trimmer ensures sufficient speed with the optimal trim of the sail, while the flight controller flies the boat when it's about a meter above the water on the foils [5][6].
The SailGP races are very close to the audience, making for an immersive and exhilarating experience. For those seeking a better understanding of the boat and each crew member's role, a photo series is available [7].
The F50 catamarans are not just about reaching the highest possible speed; they are designed for both speed and maneuverability. Unlike some faster experimental boats that only reach their top speed on a straight course, the F50 catamarans maintain their speed and maneuverability [8][9].
In the F50 catamaran team, the helmsman or driver is no longer the most important person. The crucial roles belong to the hydrofoils, the wing trimmer, and the flight controller [5][6].

The SailGP, a sports event, features the advent of revolutionary F50 catamarans that soar above the water, showcasing an entirely new dimension in sailing sport. These racing boats are engineered for both speed and maneuverability, with the hydrofoils lifting and stabilizing the hulls, reducing drag, and allowing for responsive, high-speed performance.
These catamarans, equipped withAirplane-like wing sails and hydrofoils, have redefined sailing regattas and sailing boat competitions, revolutionizing the sailing sport with their unique catamaran designs and innovative hydrofoil technology.
