An arrangement for reducing resistance to the advance of a vessel its navigation includes:at least one rotating body of revolution attached to the vessel by support and draft control means associated with its longitudinal rotation axis which is arranged perpendicular to the direction of advance of said vessel, and associated with driving means, the at least one rotating body of revolution located in front of the bow or behind the stern of said vessel. The rotation of rotating body of revolution is synchronized with the vessel’s forward speed. The rotating body of revolution closest to the hull of the vessel is separated from the hull by a clearance of approximately 5% or less of its maximum diameter. The support and draft control means are forks associated with pistons and maintain the rotating body of revolution submerged in the order of 30% of its maximum diameter during navigation.
