1. A water-sports boat configured to facilitate water sports for one or more riders as the water-sports boat moves through water, the water-sports boat comprising:

  • a hull having a transom, the hull configured to produce a wake having a port wave and a starboard wave that diverge when the hull moves through water;

    a steering rudder;

    at least one of ballast tanks, bags, or bladders;

    a port flap movable from a retracted position to a deployed position, wherein when the port flap is in the retracted position, the port flap is substantially retracted behind the transom such that no substantial portion of the port flap extends past a port-side edge of the transom and such that no substantial portion of the port flap extends past a bottom edge of the transom, and when the port flap is in the deployed position, portions of the port flap are past the transom deflecting water that has traveled along the hull of the water-sports boat;

    a starboard flap movable from a retracted position to a deployed position, wherein when the starboard flap is in the retracted position, the starboard flap is substantially retracted behind the transom such that no substantial portion of the starboard flap extends past a starboard-side edge of the transom and such that no substantial portion of the starboard flap extends past the bottom edge of the transom, and when the starboard flap is in the deployed position, portions of the starboard flap are past the transom deflecting water that has traveled along the hull of the water-sports boat;

    a port actuator configured to move the port flap between the retracted position and the deployed position; and

    a starboard actuator configured to move the starboard flap between the retracted position and the deployed position;

    wherein when the port flap is in the deployed position and the starboard flap is in the retracted position, the flaps enhance the starboard wave to form a starboard surf wave by making a face of the starboard wave substantially smoother than a face of the port wave;

    wherein when the starboard flap is in the deployed position and the port flap is in the retracted position, the flaps enhance the port wave to form a port surf wave by making the face of the port wave substantially smoother than the face of the starboard wave;

    wherein the water-sports boat changes from enhancing the starboard wave to enhancing the port wave or from enhancing the port wave to enhancing the starboard wave by respectively deploying and retracting the flaps while the water-sports boat is moving through water at a speed suitable for surfing.
