It’s just a design, but the idea is pretty cool;
the Dolphin Hydrofoil personal watercraft boasts extremely sporty looks combined with enhanced features to enrich the rider with a truly exhilarating experience. The front and rear hydrofoils act as wings, lifting the main hull of the craft above the water, increasing efficiency and the maximum achievable speed beyond the capabilities of a traditional jet ski. The elliptical front hydrofoil provides continuous lift, enabling the rider to execute high-speed banked turns. At speed, the craft seems to be flying above the water rather than skipping across its surface.
The impeller, embedded in the central dagger board of the craft, provides continuous thrust while the lift generated by the hydrofoils absorbs the majority of speed robbing turbulence from surface waves. As the craft decelerates, the hydrofoils sink and the craft comes to rest on its hull.
