ABSTRACT:
A hull-less naval vessel includes a platform completely raised from the liquid medium by of rotating floating elements fixed beneath the platform by of ball bearings. Through the lifting effect of the floating elements, the vessel will glide on the liquid surface without ploughing it; forward movement will take place almost completely in the air, thus achieving a considerable energy savings.
