Abstract

Cruising vessel with the capacity of sailing at high speeds with a reduced consumption of fuel because of the highly efficient hull thereof that extends in between lateral sides (A, B) and comprises in combination frames (3) with a minimally resistant arcuate curvature at the bow and a progressively increasing inversely turned configuration downstream the bow and with longitudinally extending foils (4) at the bow that lead within the boundaries of the hull a large part of the wave mass created during propulsion of the ship, a central longitudinal inclined keel (2) extending at progressively decreased depth from the bow till the stern so as to form a progressively broadening cavity (10) of an inverse V cross-section from approximately the middle of the ship up to the stern that leads into equivalently progressively decreased hydrostatic pressure being exerted upon the water mass entrapped within the boundaries of the hull of the ship, and lift producing blades (5) on either side of the stern that contribute towards lifting of the stern equivalently with the lifting of the bow during propulsion of the ship and towards the achievement of a constantly horizontally sailing ship that is progressively raised as speed increases and the wetted surface respectively decreases.
