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.

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 comprising a wake shaping system comprising starboard and port wake shaping devices located aft of the transom. Each wake shaping device is operable to move between a first, non-deployed position behind the transom and a second, deployed position extending outside the side of the hull or below the transom. When the starboard wake shaping device is in the deployed position, a port wakesurf wake is created. When the port of the wake shaping device is in the deployed position, a starboard wakesurf wake is created. When neither wake shaping device is deployed, a symmetrical wakeboard wake is created.

A method of operating a boat to produce a surf wake includes partially filling a transverse ballast tank, moving the boat through a body of water, rolling the boat toward either its port or starboard side to shift the water in the transverse ballast tank such that at least some of the water in the transverse ballast tank moves from one side of a longitudinal centerline of the boat to the other side of the centerline, and creating a surf wake on the side toward which the boat is rolled.

A water flow deflection device to enhance a watercraft's wake. An elongated base with two ends is aligned along the side of the watercraft. The base has a deflector interface with concentrically arranged teeth. A deflector assembly is operably attached to the base between the two ends, with a face that deflects water. The deflector's leading end is closer to the watercraft than the trailing end. The deflector assembly has a base interface with concentrically arranged teeth. Two or more suction cup assemblies attach to the elongated base to provide removable attachment, with one attached between a first end and the deflector interface and another attached between a second end and the deflector interface. The concentrically arranged teeth of the deflector interface and the base interface operably interlock, allowing rotational adjustment of the deflector relative to the base.

A device is temporarily attached to one side of the stern of a boat in order to modify the wake pattern of the boat by effectively making one side of the boat longer than the other side. The delayed wave on the opposite side of the boat from the wake shaping device allows the wave to crest over the natural wave on the side where the device is installed. In one example, the device has a frame with a side surface angled outwardly 12 degrees from the side of the boat, a mounting surface with a platform index notch configured to be positioned over a portion of a boat platform. A wedge shape utilizes water pressure to distribute the load evenly across the fastening side of the device, thereby allowing for a tight fit to the back of the boat.

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. In some embodiments, the apparatus is removably attached to the hull by one or more suction cups. The wake shaping apparatus can include a blade and be configured such that an angular orientation of the blade is adjustable. In certain embodiments, the wake shaping apparatus is inflatable.
