Water sports boat with foil displacement system

A water sports boat including foils configured to be deployed in water, wherein movement of the boat with respect to water causes the foils in certain positions to exert a down force transmitted to a hull, the water sports boat comprising:

• at least one port aft foil assembly including a port aft foil and a port aft spar, the at least one port aft foil assembly positioned port of a longitudinal axis of the boat and aft of the transverse axis and configured in a deployed position to have a downforce angle of attack to exert a second down force through the port aft spar to the hull of the boat as the hull moves through water, and configured in a stowed position to be at least one of inoperative and not exerting the second down force through the port aft spar;
• at least one starboard aft foil assembly including a starboard aft foil and a starboard aft spar, the at least one starboard aft foil assembly positioned starboard of the longitudinal axis and aft of the transverse axis and configured in a deployed position to have a downforce angle of attack to exert a third down force through the port aft spar to the hull of the boat as the hull moves through water, and configured in a stowed position to be at least one of inoperative and not exerting the third down force through the starboard aft spar;
• and
• one or more surf flaps configured to shape one transom facing side of the wake without regard to the other, thereby forming a surf wave.
