A system for enhancing a wake profile produced by a pontoon boat is provided. The system includes a pair of ramps attached to the bottom of a platform supported by at least two pontoons. The ramps may be oriented downward with a rear end of the ramp disposed in the water between the pontoons. The water flowing between the pontoons is displaced downward by the ramps, thereby increasing water displacement and directing the water to produce an improved wake profile. Downforce may be applied to the boat by one or more wake plates, with a faceted portion of the wake plate facing forward and upward, such that when water impacts the faceted portion a downforce is provided. The wake plates may be attached to the ramps or may be separate from the ramps.

Wakeboat hull control systems are provided that can include a first accelerometer operatively associated with the hull of the wakeboat to measure the acceleration of the hull along a first axis; a second accelerometer operatively associated with the hull of the wakeboat to measure the acceleration of the hull along a second axis, the first axis being non-parallel to the second axis; and processing circuitry calculating the rotation of the hull of the wakeboat about a third axis based on the acquired measurements. Wakeboat hull control methods are provided that can include using the processing circuitry to calculate the rotation of the hull of the wakeboat about a third axis based on the acquired measurements.

An adjustable surf wake system enhances a wake formed by a watercraft travelling through water. The system may include a flap for deflecting water traveling past the stern of the watercraft, and/or a positioner operably connected to the flap for positioning the flap relative to a longitudinal axis of the watercraft between a neutral position and an outward position. Positioning a port flap in its extended position enhances a starboard surf wake, and positioning the starboard flap in its extended position enhances a port surf wake. A wake modifying system for modifying a wake produced by a watercraft traveling through water may include a rudder pivotally mounted to the watercraft for steering the watercraft, a fin pivotally mounted to the watercraft substantially along a centerline of the watercraft and forward the rudder, wherein the fin pivots about an upright axis to modify the wake produced by the watercraft traveling through the water, an actuator mounted within the watercraft and operably coupled to the fin for pivoting the fin relative to the centerline, and a controller mounted on the watercraft allowing an operator to control the actuator and selectively pivot the fin to a desired angle d relative to the centerline.

A wakeboat has a hull, the hull forming a wake when moving forward in the water, with a left quiet region and a right quiet region in the wake. The hull may exhibit rotation around one or more of its roll, pitch, and yaw axes which affects the quiet regions in the wake. A gyroscope supported in the hull may be used to rotate the hull around one or more axes. Such rotation may be used to create a surf left and/or surf right configuration, and measured via one or more sensors. Other systems and methods are also provided.

Wakeboat ballast pump systems and methods are provided to monitor the operational condition and parameters of wakeboat ballast components. Systems and methods for sensing and measurement are provided to detect parameters associated with wakeboat ballast pumps and compartments, including systems and methods that can economically retrofit into existing wakeboat ballast systems. Systems and methods are also provided to enable automated action based on various operational conditions and parameters to improve the safety, automation, performance, convenience, and marketing advantage of wakeboat ballast pumps.

A recreational sport boat includes a hull having starboard and port sides and a transom, a generally horizontal platform, and a pair of wake-modifying devices positioned aft of the transom. The generally horizontal platform extends aft of the transom and is configured to support a human weighing at least 100 lbs. on an upper surface thereof. The pair of wake-modifying devices are attached to the platform. One of the wake-modifying devices is positioned on a port side of the platform's centerline, and another of the wake-modifying devices is positioned on a starboard side of the platform's centerline. Each wake-modifying device is moveable between a non-deployed position and a deployed position in which the wake-modifying device is angled downwardly at an angle relative to the top surface of the generally horizontal platform.

A boat includes at least three trim devices positioned aft of the boat's transom. To improve the boat's ability to get on place, each trim device is initially positioned to a deployed position. The speed of the boat is then determined as the boat gains speed. When the speed of the boat exceeds a first predetermined threshold, the first trim device is moved from the deployed position to a non-deployed position. When the speed of the boat exceeds a second predetermined threshold, the second trim device is moved from the deployed position to a non-deployed position. When the speed of the boat exceeds a third predetermined threshold, the third trim device is moved from the deployed position to a non-deployed position. At least one of the first, second, and third predetermined thresholds is different from the other two of the first, second, and third predetermined thresholds.

A system for a transom-mount trim tab with a fluid hinge, including a trim tab having a planar surface, a forward section located under a hull of a watercraft, a rear portion extending aft of a transom, a pair of guiding tabs coupled to the trim tab, and a forward mounting means including fluid hinge brackets, each with a mounting plate, and a containment protrusion. The system further includes a pair of aft mounting brackets configurable for variable mounting, wherein each mounting bracket includes a vertical leg having an upper portion configurable to be angulated relative to a transom of a watercraft and a bottom portion configured in a vertical orientation. The upper portion of the vertical leg and the mounting bracket have a configurable angle there-between.

A wakeboat creates a wake, the performance level of the wake varying depending upon the mass of the wakeboat, the wakeboat including a hull; an engine supported by the hull; a controller supported by the hull; a processor coupled to the controller; a memory coupled to the processor; a sensor configured to measure at least one parameter of the wakeboat, the controller being coupled to the sensor and being configured to receive data from the sensor, the controller being configured to derive the present mass of the wakeboat from said sensor data, the controller being configured to determine the present wake performance level of the wakeboat based on the present mass of the wakeboat; and a display coupled to the controller, the controller being configured to use the display to indicate the present wake performance level of the wakeboat.
