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. One or more 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.

Shaping a wave produced by a boat traveling through the water by redirecting water from one side of the boat to the opposite side of the boat. A water inlet port and a water intake scoop on one side of the boat, a water outlet at the center or opposite side/half of the boat, a water conduit between the inlet port and the outlet, and an actuator for selectively positioning the intake scoop in one of an active position in which the intake scoop extends beyond the sides or bottom of the hull and redirects ambient water into and through the inlet port, the water conduit and the outlet, and an inactive position in which the intake scoop does not extends beyond the sides or bottom of the hull and does not redirect ambient water moving past the boat into inlet port.

A water flow deflection device configured to be attached to a side of a watercraft for wake enhancement, the water flow deflection device having a water flow deflector having a stationary portion operably connected to a foldable portion, the foldable portion capable of being configured between a fully extended position and a folded position with intermediate folding positions there between, whereby the foldable portion in the folded position is configured to facilitate storage of the device. The water flow deflection device also includes a frame connected to the stationary portion of the water flow deflector, the frame including a base, at least one extension arm, and two or more suction cups for attaching the water flow deflection device to the side of the boat.

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.

The invention provides an apparatus that attaches to a hull of a boat to disrupt water flow around the hull such that a wake created behind the boat is larger, differently positioned, and/or differently shaped. The apparatus includes a base and a blade. The blade is equipped with a mount structure that attaches the base to the blade. The blade can be reversibly mountable to the base such that either face of the blade faces a desired direction. The apparatus provides tool-free adjustment between a first configuration in which the base is mounted to the blade and a second configuration in which the base and the blade are separated. In some embodiments, the apparatus is removably attached to the hull by one or more suction cups. Additionally, the apparatus can be inflatable. The invention further provides a deployable lanyard assembly and a splash deflector for use with the apparatus.

A watercraft can include a foil configured for movement between an undeployed position and a first deployed position in which the foil raises the relative position of the watercraft relative to the water line as the watercraft moves forward through the water, thereby facilitating planing of the watercraft. The foil can be configured for movement to a second deployed position in which the foil lowers the relative position of the stern end of the watercraft as the watercraft moves forward through the water, thereby modifying the wake produced by the watercraft.

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.
