A watercraft device according to the invention includes a central body and two lateral hulls, each having a shape optimized to reduce resistance to the advance motion and connected to the central body through at least one connecting arm, causing the central body to be in raised position with respect to the lateral hulls. The connecting arms have a given angle from the horizontal plan of the device, and the lateral hulls and the central body are oriented with longitudinal axes, or axes in the bow-stern direction, essentially parallel to each other. The central body connecting the lateral hulls is shaped like wing, which helps in sustaining the weight of the vehicle at high speed and exploits ground effect to increase aerodynamic efficiency. In addition, each of the lateral hulls has one or more mobile and/or fixed hydrofoil elements that extend below the corresponding lateral hull. |
