Wakesurf systems for improving and enlarging the wake behind a boat for wakesurfing. A wakesurf system can include a bracket configured to be attached to the hull of a boat. The bracket can be adhered to the hull. The wakesurf system can further include a magnetic connection between the bracket and a base of a wake forming assembly. The wake forming assembly may be collapsible and expandable. The wake forming assembly can including a base structure with a connector for attaching the base structure to the bracket when attached to the hull of the boat. The wake forming assembly can further include a water diverter pivotably attached to a second surface of the base structure and supports disposing the water diverter at an angle to the hull of the boat when the base structure is attached to the bracket and the wake forming assembly is in an expanded position.

A transom mounted fluid hinge bracket having one mounting plate that is connected at a lower distal end to a horizontal bracket portion which extends forward and aft of the transom of a watercraft in a bow to stern axial displacement, the horizontal bracket abutting the underside of the hull of a watercraft sitting flush with the underside of the watercraft, at least one fluid hinge receiver secured to the back side of the horizontal bracket portion on which the back of the substantially planar surface of the trim tab may rest, the at least one fluid hinge receiver containing the substantially planar surface in a position of the planar surface resting about parallel to the hull of the watercraft, and the at least one fluid hinge receiver without any load from the planar surface except at rest keeping the planar surface from descending below a horizon parallel to that of a horizon of the hull.

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 hull control systems and methods are provided to permit the accurate reproduction of a wake behind a wakeboat. The onboard wake control system receives data from a draft measuring system. Incorporation of the data from the draft measuring system permits accurate reproduction of a wake behind the wakeboat after a change in an onboard variable such as the number, weight or position of passengers, the weight or position of cargo and the position of trim tabs or amount/location of ballast.

A watercraft is provided with fin on its transom. The fin extends outwardly from a portion of the transom that extends into the water. The fin includes a first portion and a second portion positioned rearwardly of the first portion. The second portion is inclined downwardly and rearwardly relative to the first portion and positioned so as to provide lift and to channel water toward the propeller. The watercraft may be a pontoon boat having first and second laterally-spaced pontoons located under the deck on opposite sides of the transom. Additional fins may be mounted on the first and second laterally-spaced pontoons.
