Abstract:
1. A powerboat, comprising: a hull having a stern, said stern having a dynamic water line; a propulsion subassembly on the hull that functions as means for propelling the hull through water with sufficient power to produce a powerboat rooster tail; and means for suppressing the powerboat rooster tail, including a rooster-tail-suppressing subassembly on the boat hull that extends rearwardly of the stern; wherein the rooster-tail-suppressing subassembly includes a canopy having a downwardly facing surface extending rearwardly of the stern, said downwardly facing surface having an upper region that is disposed at least six inches above a horizontal reference plane containing the dynamic water line; wherein the canopy has a port side and a starboard side such that the port side and the starboard side extend downwardly from the downwardly facing surface so that the port side and starboard sides obstruct lateral movement of the powerboat rooster tail; wherein the port side includes first means for venting the powerboat rooster tail to port to produce a net starboard-directed lateral thrust that facilitates turning the hull to port; and wherein the starboard side includes second means for venting the powerboat rooster tail to starboard to produce a net port-directed lateral thrust that facilitates turning the hull to starboard.
