A tab body to create shaped waves in a water behind a watercraft for water sports, such as wake surfing. Wherein, the tab body comprise a portion of a wave forming tab assembly. The wave forming tab assembly are attached to the watercraft. The tab body includes a length, a width, a height, a top surface, a bottom surface, a leading end, a trailing end, one or more hydro channels, an interior edge, an exterior edge, a planar portion and an outward angle. The interior edge is proximate to a center line of the watercraft. The exterior edge is distal from the center line of the watercraft. The planar portion located proximate to the exterior edge.

A wakeboat has a hull, the hull forming a wake when moving forward in the water, with a port disturbance and a starboard disturbance in the wake. A trim tab is supported by the hull at the stern of the hull. The trim tab comprises a primary subtab and a secondary subtab. Actuators may be optionally included to reposition the trim tab more into, or more out of, the water. Other systems and methods are also provided.

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.

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.

An adjustable surf wake system can enhance a wake formed by a watercraft travelling through water. A rider control device can enable a rider to control the wake of the watercraft while riding the wake, such as for wake surfing. The rider can adjust the speed of the watercraft, can adjust the height of the wake, and/or can change the watercraft between a surf-left configuration and a surf-right configuration. The rider control device can include a position sensor. A drone can position a camera based on the position sensor of the rider control device for filming the rider.

A recreational sport boat includes a hull, having starboard and port sides and a transom, and a wake-modifying devices positioned aft of the transom. The wake-modifying device includes a plate-like member and at least one downturned surface. The wake-modifying device is pivotable between a non-deployed position and a deployed position about a pivot axis. When a wake-modifying device is in the deployed position, the downturned surface is lower than it is in the non-deployed position so as to be able to modify the boat's wake.

A wakeboat has a hull, the hull forming a wake when moving forward in the water, with a port disturbance and a starboard disturbance in the wake. Left (port) and right (starboard) trim tabs are installed at the stern of the hull. Each trim tab comprises a primary subtab and a secondary subtab. Actuators may be optionally included to reposition the trim tabs more into, or more out of, the water. Such repositioning causes the disturbance on one side of the wake to be selectively repositioned to the other side of the wake, enlarging a quiet region on the side of the wake on which the repositioned disturbance was originally positioned. Other systems and methods are also provided.
