Abstract: A fluid current producing apparatus assembly for use in a body of water includes at least one receptacle 2, current producing apparatus 3 and inflation and deflation apparatus 22c. Each receptacle 2 includes a body forming at least one enclosed inside space which further contains at least one independently inflatable and deflatable compartment 19 therein for receipt of a fluid to at least inflate at least a portion of the receptacle. Each receptacle includes a body having an inner surface 17b, outer surface 17a and at least one internal chamber 19 which is inflated by the inflation and deflation apparatus 22c which modifies the outward shape of receptacle 2.

Abstract: A fluid current producing apparatus assembly for use in a body of water includes at least one receptacle, current producing apparatus and inflation and deflation apparatus. Each receptacle includes a body forming at least one enclosed inside space which further contains at least one independently inflatable and deflatable compartment therein for receipt of a fluid to inflate at least a portion of the receptacle. Each receptacle includes a body having an inner surface, outer surface and at least one internal chamber which is inflated by the inflation and deflation apparatus which modifies the outward shape of receptacle. When the fluid is forced by apparatus over the outside surface of each receptacle or chamber from a front of the apparatus or away from the apparatus, and fluid is drawn in predominantly from the sides of the receptacles back to the apparatus in a circuit of flow. A method is also included.
