Boat with reconfigurable running surface for wake adjustment

A watersports boat comprising:

• a hull having an underside extending from a forward bow to an aft transom along a longitudinal centerline, the underside defining a running surface that contacts the water when the hull moves therein, an aft running surface section of the hull having:
• an extension member forming a re-positionable aft running surface section;
• and
• a non-repositionable aft running surface section located forward of the re-positionable aft running surface section;
• an actuator connected to the re-positionable aft running surface section;
• and
• a control system in communication with the actuator to reposition the re-positionable aft running surface section;
• a boat engine for driving the watersports boat;
• and
• at least one ballast tank
• wherein the control system includes a controller and an operating setting input unit, the controller configured to reposition the extension member based on inputs received by the operating setting input unit;
• wherein the operating setting input unit includes:
• an extension member auto deploy input, the controller automatically adjusting a position of the extension member as the watersports boat accelerates when in an auto deploy mode;
• and
• an intensity level setting input, the intensity level setting input determining a rate at which the position of the extension member is adjusted while operating in the auto deploy mode;
• wherein the control system further includes a boat operating parameters unit, the boat operating parameters unit receiving inputs of at least boat speed and ballast tank level;
• and
• wherein, in the auto deploy mode, the controller is configured to automatically reposition the extension member based on the boat speed and ballast tank level inputs.
