Patent ID: 7997221

Claim:
An apparatus for reducing drag on a nautical vessel comprising: one or more open channels; one or more air injectors; one or more enclosed lower sections; wherein said apparatus is connected to a hull of a nautical vessel; wherein said one or more open channels are on a front of said hull; wherein said one or more enclosed lower sections are wider than said one or more open channels; wherein said one or more enclosed lower sections are located at a bottom of said one or more open channels and wherein said one or more lower sections are substantially on a bottom of said hull of said nautical vessel; a plurality of outlet holes intermediate each of said open channels and a rear end of respective one of said enclosed lower sections; wherein a stream of water, generated by a nautical vessel's motion, enters said one or more air injectors and creates a depression that pulls an air into said stream of water; wherein a plurality of air bubbles are formed in said stream of water; wherein said plurality of air bubbles is carried in said stream of water down said one or more open channels to said one or more enclosed lower sections; wherein said stream of water and said plurality of air bubbles slow down and separate within said one or more enclosed lower sections such that said plurality of air bubbles forms a separated volume of compressed air that is above and compressed by said stream of water; wherein said separated volume of compressed air has a pressure greater than an external water pressure, which allows said separated volume of compressed air to exit through said plurality of outlet holes as a plurality of microbubbles.
