Wake scaling for watersports boats and related devices and methods

1. A watersports boat offering improved wake scaling comprising:

a hull having a static flow plane and an operating plane separated by an operating angle, rear corners of the hull each defining a distinct transition from a respective side of the hull to a transom of the hull;

wherein a shape of the outer perimeter of the hull along the operating plane includes a pair of outward curves, each outward curve curving away from a hull centerline moving forwardly of a respective one of the rear corners of the hull.

2. The watersports boat of claim 1 , wherein the operating angle is at least 3 degrees.

3. The watersports boat of claim 2 , wherein the operating angle is 6-8 degrees.

4. The watersports boat of claim 1 , wherein each of the outward curves has a length, moving forwardly of the respective one of the rear corners, of at least 8 inches.

5. The watersports boat of claim 4 , wherein the length of each of the outward curves is at least 18 inches.

6. The watersports boat of claim 5 , wherein the length of each of the outward curves is 20 to 21 inches.

7. The watersports boat of claim 1 , further comprising a surf system including:

a pair of plates, each of the plates being extendable and retractable from the transom past the respective one of the rear corners;

a respective driver operable to extend and retract each of the plates; and

a controller operable to control the drivers to extend and retract each of the plates.

8. The watersports boat of claim 7 , wherein the controller receives a speed input and is configured with program instructions to automatically partially deploy both the plates when the speed input indicates a boat speed is in excess of an upper speed threshold.

9. The watersports boat of claim 8 , wherein the controller is configured with program instructions to automatically partially deploy both the plates to a deployment length of less than ½ inch past the respective one of the rear corners.

10. The watersports boat of claim 9 , wherein the controller is configured with program instructions to automatically partially deploy both the plates to a deployment length of less than ¼ inch past the respective one of the rear corners.

11. The watersports boat of claim 8 , wherein the controller is further configured with program instructions to fully retract both of the respective plates when the speed input indicates the boat speed is less than a lower speed threshold.

12. The watersports boat of claim 11 , wherein the upper and lower speed thresholds are separated by a control band.

13. The watersports boat of 11 , wherein the controller is further configured with program instructions to:

if the surf system is on, automatically disable normal surf system operation when the speed input indicates the boat speed is in excess of the upper speed threshold; and

if the surf system is on, automatically resume normal surf system operation when the speed input indicates the boat speed is less than the lower speed threshold.

14. A method of improving wake scaling for watersports boat, the method comprising:

including, in a shape of an outer perimeter of a hull of the watersports boat moving forwardly of each rear corner of the hull marking a distinct transition from the transom to a respective side of the hull, a respective outward curve which curves away from a hull centerline.

15. The method of claim 14 , wherein a length of each respective outward curve is at least 8 inches.

16. The method of claim 15 , wherein the length of each respective outward curve is 8 to 21 inches.

17. The method of claim 16 , wherein the length of each respective outward curve is 18 to 21 inches.

18. The method of claim 17 , wherein the length of each respective outward curve is 20 to 21 inches.

19. The method of claim 15 , wherein the length of each respective curve is greater than 12 inches.

20. The method of claim 19 , wherein the length of each respective curve is greater than 18 inches.
