A hydrofoil comprising a flat vessel of aerodynamic profile which, together with small planes, produces an aerodynamic lift, and the broad base of the hull contains a set of flexible fins whose cross-sections reduce from relatively thick inner ends of relatively large cross-section to relative thin outer ends of relatively small cross-section, that are fixed at their thicker end, that are inclined toward the end opposite the forward movement of the vessel, constructed and arranged to meet the water at their large surfaces, and to generate a hydrodynamic lift, with air flow propulsion, by the, for example, propeller, turboprop, or turbofan type turbodrive engines in the upper part.
