1. A leveling control system for adjusting an attitude of a boat deck supported by at least a starboard side pontoon, a port side pontoon, and a middle pontoon arranged between the port side pontoon and the starboard side pontoon, the leveling control system comprising:
a starboard side actuator operable to move the starboard side pontoon relative to the boat deck from a retracted position, where the starboard side pontoon is proximate to an underside of the boat deck, to an extended position, where the starboard side pontoon is moved further from the underside;
a port side actuator operable to move the port side pontoon relative to the boat deck from a retracted position, where the port side pontoon is proximate to an underside of the boat deck, to an extended position, where the port side pontoon is moved further from the underside;
a middle actuator operable to move the middle pontoon relative to the boat deck from a retracted position, where the middle pontoon is proximate to an underside of the boat deck, to an extended position, where the middle pontoon is moved further from the underside;
a level sensor providing readings indicative of the attitude of the boat deck;
a controller for activating the starboard side actuator, the middle actuator, and/or the port side actuator to thereby cause extension or retraction of the starboard side pontoon, the middle pontoon, and/or the port side pontoon, respectively, wherein the controller is configured to adjust position of the port side pontoon, the middle pontoon, and/or the starboard side pontoon to thereby orient the boat deck in a desired attitude.
