Following the successful collaboration on the BGH-HSV project, the Bluegame shipyard decided to team up with CH again to develop a foil-assisted multihull capable of drastically reducing fuel consumption while simultaneously increasing comfort at sea. The synergy with Caponnetto-Hueber has resulted in what is perhaps the flagship boat of 2025 in its category.
Bluegame is a shipyard with innovation ai its soul and courage at its heart, just like CH. The client’s brief was simply to revolutionize boating, as usual, drastically reducing the yacht’s fuel consumption and increasing comfort, especially in rough seas. The foil solution was the one chosen and CH’s task was to find the best combination of hull and foil that satisfied a long series of requirements. An optimization that is possible only using sophisticated calculation tools.
Dozens of hull and foil combinations were tested in RANS. Ultimately, the best solution was a fixed central foil, without control surfaces, relatively submerged but no deeper than necessary to increase the propeller immersion. Starting with straight-line simulations in calm water, the best candidates moved on to seakeeping simulations to check the reduction in vertical acceleration and then maneuverability, verifying banking angle and lateral acceleration. It was quickly realized that the aft stabilizers (elevators) present on similar boats could be eliminated.

During the 33rd America’s Cup cycle, Mario Caponnetto contributed to hydrodynamic assessment workstreams aligned with the BMW Oracle wing-sail platform, the configuration that ultimately won the Match. This milestone marked the shift toward aero-hydrodynamic integration in Cup design culture.

In 2021, Caponnetto Hueber led the CFD, foil design, and hydrodynamic engineering for the AC75 of Luna Rossa Challenge, the eventual Prada Cup winner. We deployed multiscale CFD and aero-hydro coupling to ensure optimum lift and control. Rapid iteration delivered performance gains under tight competition timelines.
