A boat hull having a two-stage flow chamber. The first stage flow chamber starts about amidships as a V-shape fairing upward at a shallow angle and flattening out about halfway to the stern. The second stage flow chamber starts at the end of the forward flow chamber curving upward at a greater angle than the first stage and curving downward slightly at the stern. The second state flow chamber has an inverted V-shape portion connected to the bottom by a pair of narrow sidewalls spreading slightly outward. The forward flwo chamber delivers water to the aft flow chamber free from turbulence. The propeller is disposed in the aft flow chamber and splayed slighly to port. Water exits from the aft flow chamber with minimum turbulence and cavitation.

A boat hull having at least one two-stage flow chamber comprising: a V-bottom hull having a forward flow chamber stage defined by a first surface beginning with a flow entry portion parallel to adjacent surfaces of the boat hull and gradually increasing in depth as said forward stage extends toward an aft end of the boat hull, said first surface angularly varying from a plane parallel to said surface of the hull to a plane lying substantially parallel to a surface of water when the boat hull is at rest in the water; and an aft flow chamber stage aligned with an aft end of said forward flow chamber stage and defined by a second surface beginning at said aft end of said forward flow chamber stage and curving upward into an inverted V-shape and having a pair of opposed planar sides connecting said second surface to said boat hull.
