Control system for water sports boat with foil displacement system

A method of controlling one or more foils of a water sports boat including a hull, wherein movement of the water sports boat with respect to water causes the one or more foils in certain positions to exert a downforce that is transmitted to a hull, the method comprising:

• receiving a deploy signal responsive to a driver of the water sports boat deploying one or more foil assemblies, each foil assembly including a foil and a spar, each foil having a stowed position and a deployed position, said deployed position including one or more downforce positions where said foil is positioned at a downforce angle of attack, when said foil is deployed at one of said downforce angles of attack, said foil is configured to exert a downforce through the spar to the hull of the water sports boat as the hull moves through water;
• activating one or more actuators operably connected to said one or more foil assemblies to move said one or more foils away from said stowed position and toward said deployed position;
• monitoring a deploy time as said one or more foils moves away from said stowed position toward said deployed position;
• and
• when said deploy time reaches a threshold, ceasing said movement.

• receiving a deploy signal responsive to a driver of the water sports boat deploying one or more foil assemblies, each foil assembly including a foil and a spar, each foil having a stowed position and a deployed position, said deployed position including one or more downforce positions where said foil is positioned at a downforce angle of attack, when said foil is deployed at one of said downforce angles of attack, said foil is configured to exert a downforce through the spar to the hull of the water sports boat as the hull moves through water;
• and
• activating one or more actuators operably connected to said one or more foil assemblies to move said one or more foils away from said stowed position and toward said deployed position;
• wherein said one or more foil assemblies comprises:
• a forward foil assembly including a forward foil and a forward spar, the forward foil assembly positioning the forward foil, when deployed, forward of a transverse axis at a center of gravity of the water sports boat, the forward foil, when deployed at a downforce angle of attack, also configured to exert a first down force through the forward spar to the hull of the water sports boat as the hull moves through water;
• a port aft foil assembly including a port aft foil and a port aft spar, the port aft foil assembly positioning the port aft foil, when deployed, port of a centerline axis of the water sports boat and aft of the transverse axis, the port aft foil, when deployed at a downforce angle of attack, also configured to exert a second down force through the port aft spar to the hull of the water sports boat as the hull moves through water;
• and
• and a starboard aft foil assembly including a starboard aft foil and a starboard aft spar, the starboard aft foil assembly positioning the starboard aft foil, when deployed, starboard of the centerline axis and aft of the transverse axis, the starboard aft foil, when deployed at a downforce angle of attack, also configured to exert a third down force through the port aft spar to the hull of the water sports boat as the hull moves through water, wherein any individual or combination of the first, second and third down forces draw the hull of the water sports boat down into the water to increase a quantity of water displaced and increase a size of a wake.

• receiving a deploy signal responsive to a driver of the water sports boat deploying one or more foil assemblies, each foil assembly including a foil and a spar, each foil having a stowed position and a deployed position, said deployed position including one or more downforce positions where said foil is positioned at a downforce angle of attack, when said foil is deployed at one of said downforce angles of attack, said foil is configured to exert a downforce through the spar to the hull of the water sports boat as the hull moves through water;
• activating one or more actuators operably connected to said one or more foil assemblies to move said one or more foils away from said stowed position and toward said deployed position;
• and
• activating said one or more actuators operably connected to said one or more foil assemblies to move said one or more foils to adjust a corresponding angle of attack;
• wherein said activating to adjust said angle of attack is responsive to receiving a signal from said driver using a driver input device;
• and
• wherein said water sports boat includes a driver's console having a touchscreen display including display indicia, and wherein said driver touches display indicia indicating current or available positions of said one or more foils.
