Abstract: In one embodiment, the aerodynamic control system includes a pair of airfoil shaped vertical stabilizing structures rising above the aft deck portion of the motorboat. A vertical stabilizer is disposed on either side of the deck. Each vertical stabilizer includes a movable rudder along its aft region which arcuately moves about an axis longitudinally extending through the rudder. The control system also includes an airfoil shaped elevator structure having end portions fixed to inboard opposing top sections of the vertical stabilizers and an arcuately movable elevator portion extending between the fixed first and second ends. A control mechanism arcuately moves the elevator portion thereby altering the angle of attack attitude of the elevator. Another control mechanism synchronously moves the rudders to assist steerage of the motorboat.
