A hydrofoil wing structure is disclosed to be employed as an accessory for a marine propulsion device, to be disposed above and mostly aft of the propelling means of such a device, to contour and concentrate the kinetic energy in the hydrodynamic vortex created by the propelling means; to reduce turbulence, vibration and noise by reflecting acoustic energy downwardly from the surface of the water; to increase the efficiency of such a device powered by an electric battery; to improve the steering and maneuverability of the vessel by providing a rudder for...
A hydrofoil accessory for a marine propulsion device which has propeller means, comprising: a wing having a rigid center surface, two rigid side surfaces opposite each other and extending downwardly from the center surface, and two rigid rudder surfaces opposite each other and extending downwardly from the side surfaces; the center surface having a front end and a rear end, the center surface being substantially parallel to the surface of the water when the wing is in use; the side surfaces being substantially mirror-images of each other, disposed on eit...
