A wake adjustment system for a boat may include a pair of wake adjustment devices mountable at the stern of the boat to deflect water moving past a stern trailing edge of the boat's running surface. A wake adjustment device includes a water deflector that is rotatable about a first pivot axis for varying a degree of wake adjustment. The pivot axis is non-parallel to the boat's stern trailing edge.

1. A boat comprising: a hull having a bottom side with a running surface extending from a bow to a stern along a longitudinal hull centerline, the running surface having a trailing edge at the stern where water releases from the running surface when the boat moves forward though water;a pair of wake adjustment devices mounted to the boat aft the stern trailing edge in opposed positions about the centerline, each wake adjustment device having a water deflector pivotally attached to the wake adjustment device along a first pivot axis that is non-parallel with the stern trailing edge, each water deflector being rotatable about the first pivot axis so as to modify the boat's wake; anda control system in communication with each wake adjustment device, the control system being operable to impart rotation about each first pivot axis to each water deflector independent of the other water deflector to make a surf wake behind the boat. 2. The boat of claim 1, wherein the stern trailing edge is formed where the running surface meets a transom of the boat and the first pivot axis extends horizontally across the wake adjustment device. 3. The boat of claim 1, wherein the first pivot axis angles inboard toward a vertical plane defined by the centerline so as to deflect water in an outboard direction when the boat moves forward through water. 4. The boat of claim 3, wherein the first pivot axis projected onto the vertical plane forms an acute angle with the vertical plane. 5. The boat of claim 3, wherein the first pivot axis projected onto the vertical plane forms an acute angle of 50 to 85 degrees with the vertical plane. 6. The boat of claim 1, wherein each wake adjustment device is rotatable about a second pivot axis positioned forward the first pivot axis. 7. The boat of claim 1, wherein each wake adjustment device further includes: a mounting member mounting the device to the boat;an extension member connected to the mounting member and extending aft the mounting member, the first pivot axis extending across the extension member; anda second pivot axis forming the connection between the mounting member and extension member. 8. The boat of claim 7, wherein the extension member is a substantially horizontally oriented plate having a bottom surface that can be positioned substantially coplanar with the running surface immediately forward the stern trailing edge by rotation about the second pivot axis. 9. The boat of claim 1, wherein each water deflector is rotatable upwardly and downwardly about the first pivot axis. 10. A wake adjustment system for a boat including a hull having a bottom side with a running surface extending from a bow to a stern along a longitudinal hull centerline, the wake adjustment system comprising: a pair of wake adjustment devices mountable to the stern in opposed positions about the centerline, each wake adjustment device having: (i) a mounting member at a forward end of the device that can mount the device to the boat;(ii) an extension member having a forward edge connected to the mounting member, the extension member extending aft the mounting member to a first pivot axis extending horizontally across the extension member from an outboard side to an inboard side thereof, the first pivot axis being non-parallel to the forward edge of the extension member; and(iii) a water deflector connected to the extension member at the first pivot axis, the water deflector being rotatable about the first pivot axis for varying a degree of wake adjustment. 11. The wake adjustment system of claim 10, wherein the first pivot axis angles in an inboard and forward direction so as to allow the water deflector to deflect water in an outboard direction. 12. The wake adjustment system of claim 10, wherein the first pivot axis angles in an inboard and forward direction to form an acute angle with a vertical plane defined by the centerline when the wake adjustment devices are mounted to the boat. 13. The wake adjustment system of claim 10, wherein the first pivot axis angles in an inboard and forward direction to form an acute angle of 50 to 85 degrees with a vertical plane defined by the centerline when the wake adjustment devices are mounted to the boat. 14. The wake adjustment system of claim 10, wherein each wake adjustment device is rotatable about a second pivot axis positioned forward the first pivot axis. 15. The wake adjustment system of claim 10, wherein each wake adjustment device further includes a second pivot axis forming a connection between the mounting member and extension member. 16. The wake adjustment system of claim 10, wherein the extension member is a substantially horizontally oriented plate having a bottom surface that can be positioned substantially coplanar with the running surface immediately forward the stern trailing edge by rotation about a second pivot axis positioned forward the first pivot axis. 17. A method of generating a surf wake behind a boat including a hull having a bottom side with a running surface extending from a bow to a stern along a longitudinal hull centerline, the running surface having a trailing edge at the stern where water releases from the running surface when the boat moves forward though water, the method comprising: imparting rotation to a water deflector of a wake adjustment device mounted to a stern of a boat on either a port or starboard side of the centerline in such a way that the water deflector deflects water that moved past the stern trailing edge and creates a surf wake behind the boat; the water deflector being rotatably connected to the wake adjustment device at a first pivot axis that extends horizontally across the wake adjustment device and is non-parallel with the stern trailing edge. 18. The method of claim 17, wherein the first pivot axis angles inboard toward a vertical plane defined by the centerline so as to deflect water in an outboard direction when the boat moves forward through water. 19. The method of claim 18, wherein the first pivot axis projected onto the vertical plane forms an acute angle with the vertical plane. 20. The method of claim 19, wherein the first pivot axis projected onto the vertical plane forms an acute angle of 50 to 85 degrees with the vertical plane. 21. The method of claim 17, wherein the wake adjustment device is rotatable about a second pivot axis positioned forward the first pivot axis. 22. The method of claim 17, wherein the wake adjustment device includes: a mounting member mounting the device to the boat;an extension member connected to the mounting member and extending aft the mounting member, the first pivot axis extending across the extension member; anda second pivot axis forming the connection between the mounting member and extension member. 23. The method of claim 22, wherein the extension member is a substantially horizontally oriented plate having a bottom surface that can be positioned substantially coplanar with the running surface immediately forward the stern trailing edge by rotation about the second pivot axis. 24. The method of claim 17, wherein the water deflector is rotatable upwardly and downwardly about the first pivot axis. 25. A boat control system for a boat including a hull having a bottom side with a running surface extending from a bow to a stern along a longitudinal hull centerline, the running surface having a trailing edge at the stern where water releases from the running surface when the boat moves forward though water, the boat including port and starboard side water deflectors mounted at the stern in such a way that the water deflectors can deflect water that moves past the stern trailing edge, the boat control system comprising: a non-transitory processor readable memory medium storing a maximum surfing speed and processor instructions that are executable to cause a processor to (a) receive boat speed data from the boat and (b) select an operational mode for controlling movement of the water deflectors based on the boat speed data, the operational modes including: (i) a surf mode wherein the water deflectors are operational to rotate through a first range of rotation and create a surf wake behind the boat up to the maximum surfing speed; and(ii) a trim tab mode wherein the water deflectors are operational to rotate through a second range of rotation that is restricted relative to the first range of rotation above the maximum surfing speed.
