Abstract
A boat hull having a ventilated boat keel is disclosed. In one embodiment, the ventilated boat keel may be a longitudinal vent tube from bow to stern, which runs down the center of the hull and branches off into multiple vent openings along the stepped hull. In another embodiment, the ventilated boat keel may be a longitudinal vent tube from bow to stern, which runs down the center of the hull and branches off into multiple vent openings along a traditional hull design. The ventilated boat keel creates a layer of micro-bubbles along the bottom of the boat. The micro-bubbles reduce friction and drag and allow for the boat to travel at a higher rate of speed using less fuel.
