A self-propelled waterborne wave riding system includes a vessel having at least one motor and control system for navigating and propelling the vessel along a body of water. A rider section is located along the top of the vessel and includes a lower platform at the front of the vessel, an upper platform at the back of the vessel, and an elongated angled ride surface that extends between the upper and lower platforms. A pump system is provided along the vessel and includes an impeller assembly that is mechanically coupled to an inboard motor and a water pipe. Water received by the impeller is directed through the water pipe to a horizontally oriented nozzle in the lower platform which pushes the water over the ride surface. Openings in the upper platform return the used water into the body of water.

The present disclosure describes recreational watercraft that provide a ballast system and an open platform passenger deck. An example is an aluminum hull including a ballast system to regulate displacement by the recreational watercraft and an open platform passenger deck as an integral upper surface to the aluminum hull. Multiple sides, continuous from the aluminum hull, include a stern side, a bow side, a port side, and a starboard side that surround a perimeter of the open platform passenger deck. An inboard power plant is located within a stern portion of the aluminum hull to propel the recreational watercraft.

A wave generating apparatus mobile application controller and method are provided, in which a mobile controller actuates a plurality of wave generating chambers in sequence using a delay between the actuation of each chamber to produce a rideable wave in a pool. The mobile application controller allows the user to select the exact type of wave to be produced by the wave generator apparatus by selecting the size, shape, and pattern of the wave. The application also allows the user to use a camera to photograph or record herself or someone else, even while riding a wave.

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.

A boat includes at least three trim devices positioned aft of the boat's transom. To improve the boat's ability to get on place, each trim device is initially positioned to a deployed position. The speed of the boat is then determined as the boat gains speed. When the speed of the boat exceeds a first predetermined threshold, the first trim device is moved from the deployed position to a non-deployed position. When the speed of the boat exceeds a second predetermined threshold, the second trim device is moved from the deployed position to a non-deployed position. When the speed of the boat exceeds a third predetermined threshold, the third trim device is moved from the deployed position to a non-deployed position. At least one of the first, second, and third predetermined thresholds is different from the other two of the first, second, and third predetermined thresholds.

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 water or other amusement attraction that includes an inflatable portion or material. A cavity of the attraction is located underneath an upper surface, the upper surface configured to support a flow of water and at least one rider thereon. A volume of water is configured to be disposed within the cavity, the upper surface floating upon the volume of water while connected to at least one side wall, floor, and/or nozzle structure. A pump and nozzle assembly, positioned outside of the cavity, communicates with the water within the cavity for flowing a portion of the water over the upper surface. A drainage portion, adjacent to the upper surface, drains the flowing water back into the cavity for recirculation. Support components, such as a plurality of beams or an inflatable grid structure help maintain stability for the attraction.

A watercraft includes a vessel body, a marine propulsion device and a guide. The marine propulsion device is attached to the vessel body and includes a water stream generator that propels the vessel body. The guide is provided on the vessel body and extends astern of the vessel body and toward a center of the vessel body in a width direction of the vessel body from a position located sideward of the water stream generator. The guide inwardly directs water flowing on one lateral side of the vessel body such that confluent timing of the water flowing on the one lateral side of the vessel body and water flowing on the other lateral side of the vessel body is caused to occur earlier than when the guide is not provided on the vessel body.

An example is an aluminum hull including a ballast system to regulate displacement by the recreational watercraft and an open platform passenger deck as an integral upper surface to the aluminum hull. Multiple sides, continuous from the aluminum hull, include a stern side, a bow side, a port side, and a starboard side that surround a perimeter of the open platform passenger deck. An inboard power plant is located within a stern portion of the aluminum hull to propel the recreational watercraft.

Recreational watercraft and methods of operating recreational watercraft are described. Recreational watercraft can include an aluminum hull, a plurality of ballast tanks, a first surface defining a first opening that extends from an interior of a ballast tank of the plurality of ballast tanks to an exterior of the hull, a valve configured to selectively open or close the first opening, and a second surface defining a second opening that is fixed permanently open and extends from an interior of the ballast tank through a bottom portion of the hull to an exterior of the hull.
