Abstract: 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 stage 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 slightly to port. Water exits from the aft flow chamber with minimum turbulence and cavitation.

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.
