A wakeboat has a hull, the hull forming a wake when moving forward in the water, with a port disturbance and a starboard disturbance in the wake. Left (port) and right (starboard) trim tabs are installed at the stern of the hull. Each trim tab comprises a primary subtab and a secondary subtab. Actuators may be optionally included to reposition the trim tabs more into, or more out of, the water. Such repositioning causes the disturbance on one side of the wake to be selectively repositioned to the other side of the wake, enlarging a quiet region on the side of the wake on which the repositioned disturbance was originally positioned. Other systems and methods are also provided.
