The second plate potion of each wake shaping device is operable to pivot approximately 90° between a first, non-deployed position behind the transom and a second, deployed position extending outside the side of the hull and below the transom. When the second portion of the starboard wake shaping device is in the deployed position, a port wakesurf wake is created. When the second portion of the port of the wake shaping device is in the deployed position, a starboard wakesurf wake is created. When neither wake shaping device is deployed, a symmetrical wakeboard wake is created. ## Claims ### Claim 1 A boat comprising a wake shaping system for wakeboarding and wakesurfing, the boat comprising: a hull comprising a bow and a transom, starboard and port sides, a longitudinal axis extending from the bow to the transom along a centerline, a lateral axis extending from the port side to the starboard side substantially perpendicular to the longitudinal axis, and a transom axis extending from an upper edge of the transom to a lower edge of the transom substantially perpendicular to the longitudinal axis;
