A pontoon boat assembly includes at least two outer pontoon floats and at least one center pontoon float. A deck is supported above the floats. A propulsion system in the preferred form of a V-drive with a rear-facing propeller is provided for moving the pontoon boat across a body of water and causing wakes to trail behind the pontoon float in the path of the pontoon floats. At least one wake panel is supported off a stern end of at least one of the outer pontoon floats and is slideable to a lowered position for selectively engaging the body of water and altering the trailing wake to shape the wake. At least one hydrofoil is engagable with the body of water for drawing the stern end of the boat downwardly during propulsion of the pontoon boat to increase the size of the shaped wake.

A pontoon for providing buoyant force to a floating craft comprises a barrel having front and rear ends and a fin extending outwardly from an outer surface of the barrel. The fin includes a first portion and a second portion positioned rearwardly of the first portion. The first portion extends at least generally parallel with or coincident with a lateral, horizontally extending centerline of the barrel. In order to enhance stability, improve handling, and/or inhibit motor cavitation, the second portion is inclined downwardly and rearwardly relative to the rear end of the first portion. Also disclosed is a pontoon boat fitted with fins on the pontoons and/or on the transom.

A pontoon boat includes a deck supported by two pontoons extending in a fore-aft direction and water diverters mounted to the pontoons, the water diverters being movable between a neutral position that does not substantially divert water and a deployed position extended laterally from the boat to divert water.

A combination trim tab and interceptor comprises a housing and a trim tab pivotably coupled to the housing. An interceptor blade is reciprocatingly received by the housing. A cam is coupled to the trim tab and the interceptor blade. The cam is coupled to the trim tab by a link which applies a rotary force when the trim tab pivots relative to the housing. The cam is coupled to the interceptor blade such that the interceptor blade functions as a cam follower. An actuator actuates the trim tab to pivot relative to the housing. Pivoting of the trim tab results in the cam applying a force to the interceptor blade, causing the interceptor blade to reciprocate relative to the housing. The cam may be configured so a stroke of the interceptor blade and a stroke of the actuator are non-linear. The actuator may be an electromechanical linear actuator.

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 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.

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 system for automatically modifying the lean of a catamaran during a turn includes a pair of fins, each substantially permanently affixed to the inside edge of the left and right hull, plus a pair of vertically displacing plates that extend, one at a time, from the left or right hull, into the body of water. Individually, the fins or plates modify the lean of a catamaran during a turn such that the tilt is neutral or inboard, versus outboard without either. The cumulative effect of using both is substantial and synergistic.

A Method and Apparatus for Planing Boat Ballast System have been disclosed. By using ballast forward of a transverse step forward of the stem and by using a ballast opening in or at a riser of the transverse step, enhanced stability is possible with protection from flooding and with efficiency of ballast admission and release, simplicity of practice, and ease and safety of inspection and cleaning
