Design Optimization of Subcavitating Hydrofoils for America's Cup Class Yachts

The introduction of hydrofoil technology has significantly increased speed while maintaining the same wind conditions. This advancement reduces skin friction and wave drag, although there is a slight increase in induced drag due to the wing being submerged. Consequently, hydrofoils have gained popularity in recent years, driven by the desire for higher speeds.

On the left, we see a new design known as a wing foil, which benefits from lower drag forces. This allows for a lightweight construction that can be easily held by hand, enhancing its appeal for recreational use. Additionally, the market has seen a rise in electric-powered hydrofoils, providing further options for enthusiasts.

Moreover, the potential applications of hydrofoil technology extend beyond recreation. The right side of the slide highlights the significant advantages in industry, including reduced fuel consumption and improved seakeeping characteristics. These benefits have led to the adoption of hydrofoils in competitive sailing, such as in the America's Cup.
