An adjustable wake setting device for modifying a wake produced by a watercraft traveling through water. The system has a mounting member dimensioned and configured for attachment to the watercraft, a foil dimensioned and configured for movement between a stowed position adjacent the mounting member, out of the water, and an active area below the mounting member, in the water, such that the foil adjusts a relative position of the watercraft in the water thereby modifying the wake produced by the water craft traveling through the water, a linkage movably securing the foil to the mount, the linkage being dimensioned and configured for adjustably positioning the foil in the stowed position and the active area, an actuator mounted on the mounting member and connected to the linkage for moving the linkage such that the foil moves between the stowed position and the active area, and a controller for selectively actuating the actuator thereby selectively moving the foil between the stowed position and the active area. A method of using the adjustable wake setting device is also disclosed.

What is claimed is: 1. A wake modifying system for modifying a wake produced by a watercraft traveling through water, the system comprising: a mounting member dimensioned and configured for attachment to the watercraft; a foil dimensioned and configured for movement between a stowed position adjacent the mounting member, out of the water, and an active area below the mounting member, in the water, such that the foil lowers a relative position of a stern end of the watercraft in the water thereby modifying the wake produced by the watercraft traveling through the water; a linkage movably securing the foil to the mount, the linkage being dimensioned and configured for adjustably positioning the foil in the stowed position and the active area; an actuator mounted on the mounting member and connected to the linkage for moving the linkage such that the foil moves between the stowed position and the active area; and a controller for selectively actuating the actuator thereby selectively moving the foil between the stowed position and the active area. 2. The wake modifying system of claim 1, wherein the active area includes a plurality of active positions, wherein each active position of the foil modifies the wake in varying degree. 3. The wake modifying system of claim 2, wherein the plurality of active positions of the foil are incrementally spaced within the active area. 4. The wake modifying system of claim 3, wherein the actuator is a step motor configured for moving the foil between the incrementally spaced active positions. 5. The wake modifying system of claim 1 in combination with a watercraft, wherein the mounting member is mounted to a transom of the watercraft. 6. The wake modifying system of claim 1, wherein the actuator includes at least one linear actuator having one end pivotally attached to the mounting member and another end pivotally attached to the linkage, and the controller being configured to output a control signal to the at least one linear actuator such that the actuator moves the linkage to move the foil between the stored position and active area. 7. The wake modifying system of claim 1, wherein the controller is configured for control by a user within the watercraft. 8. The wake modifying system of claim 1, wherein the controller is configured to control the actuator in response to one or more operational parameters of the watercraft. 9. The wake modifying system of claim 8, wherein the controller is configured to prohibit the actuator from moving the linkage and foil between the stored position and active area unless speed of the watercraft is less than a predetermined threshold speed. 10. The wake modifying system of claim 9, wherein the predetermined threshold speed is approximately 10 miles per hour. 11. The wake modifying system of claim 8, wherein the controller is configured to allow the actuator to move the linkage and foil between a plurality of active positions within the active area when the speed of the watercraft is above the predetermined threshold speed but below a predetermined maximum speed. 12. The wake modifying system of claim 11, wherein the predetermined maximum speed is approximately 25 miles per hour. 13. The wake modifying system of claim 8, wherein the controller is configured to prevent the actuator to move the linkage and foil between a plurality of active positions within the active area when the speed of the watercraft is greater than approximately 10 miles per hour. 14. The wake modifying system of claim 8, wherein the controller prohibits the actuator from moving the linkage and the foil when the speed of the watercraft is approximately zero. 15. A wake modifying system for modifying a wake produced by a watercraft moving through water, the system comprising: a mounting body, the mounting body being configured to be secured to the watercraft; a linkage including an arm being pivotably attached at an upper end thereof to the mounting body; a water foil attached to a lower end of the arm, the water foil being dimensioned and configured for movement between a stowed position adjacent the mounting body and out of the water and an active area below the mounting member and in the water, the water foil being configured for enhancing the wake produced by the moving watercraft; and an actuator pivotably attached at one end to the mounting body and pivotably attached at another end to the arm adjacent the upper end; wherein the actuator is configured for positioning the arm and the water foil in response to a control signal. 16. The wake modifying system of claim 15 wherein the mounting body is secured to a transom of the watercraft. 17.
