A device for reducing the resistance of water surface vessels
Patent, 2020

An object of the invention is to decrease the hull resistance of a water surface vessel. This object is reached with a water surface vessel extending in a longitudinal direction parallel to an intended direction of straight travel, the vessel presenting a transom, wherein the vessel is arranged to travel in a recirculating zone speed interval in which water is moving towards the transom in a recirculating zone behind the transom, wherein the vessel comprises a pushing device presenting a pushing surface located in relation to the intended direction of straight travel of the vessel behind the transom, at least a portion of the pushing surface facing at least partly backwards in relation to the intended direction of straight travel of the vessel, which pushing surface is arranged to be at least partly submerged into the recirculating zone when the vessel is travelling in the recirculation zone speed interval.
