A boat control system includes an imager to image a user towed by a hull, an image processor to determine a predetermined state of the user from an image captured by the imager, and a controller configured or programmed to perform a control to adjust a thruster operable to change a propulsion state of the hull based on the predetermined state of the user determined by the image processor to change the propulsion state of the hull.

Wakeboat fluid housing compartment fluid level sensing assemblies are provided. The assemblies can include: a wakeboat having a hull; a fluid housing compartment associated with the hull; a nonconductive sensor chamber positioned within the fluid housing compartment of the hull; and at least a pair of conductive electrodes associated with the sensor chamber, at least one of the pair of conductive electrodes being positioned within the nonconductive sensor chamber and electrically isolated from fluid within the fluid housing compartment. Methods for sensing a fluid level within a fluid housing compartment aboard a wakeboat are also provided. The methods can include: maintaining fluid communication between the fluid level within the fluid housing compartment and a sensor chamber; and determining the electrical communication between at least a pair of electrodes operatively associated with the sensor chamber.

The present disclosure generally pertains to a lateral displacement surf system and methods of laterally displacing a watercraft to generate wake. The lateral displacement system includes at least one pair of foils configured to be extended from a hull on a first side of the watercraft at a level of approximately the waterline. Upon forward movement of the watercraft with extended foils, the watercraft is rotated about its vertical axis toward the first side and generates waves sufficient for the conduction watersport activities on a second side of the watercraft. In some instances, foils are built into the hull and extended from this position, while in other instances the foils are attached to the hull using attachment structures. Rotation of the foils about an axis of rotation approximately perpendicular to a longitudinal axis of the watercraft alters the angle of attack of the foils relative to the waterline.

A foil displacement system includes one or more foils that can be deployed and stowed. When deployed, each foil can exert downforce or uplift depending on its orientation. For example, each foil may be positioned to have an angle of attack that creates a downward force effectively transmitted to the hull to pull the hull deeper within the water to, for example, create a larger wake. Use of the foil displacement system can enhance or replace the use of a ballast tank system, can be integrated into a new boat or retrofitted to existing boats, can be electronically or manually positioned, can enhance activities such as wake surfing, wake boarding, water skiing or other similar or related water sports.

A Method and Apparatus for Wake Enlargement System have been disclosed. By using water pick-ups that are mounted on a boat, controlled filling of ballast tanks is possible without the use of pumps.

Wakeboats that include an aquatic invasive species control apparatus are provided. These wakeboats can include: a wakeboat with a hull; at least one throughhull fitting in the hull of the wakeboat; an irradiation chamber in fluid communication with the at least one throughhull fitting, the irradiation chamber having a radiation source; and at least one water destination aboard the wakeboat. Methods for irradiating invasive aquatic species aboard a wakeboat are also provided. The methods can include: receiving water from outside the wakeboat hull; and irradiating water aboard the wakeboat prior to discharging the water.

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.

A pump intake adapter for pumping shallow levels of fluid from a surface to be drained, the pump intake adapter including a connection on the pump intake adapter to convey the fluid away from the pump intake adapter; an intake surface on the pump intake adapter; and a portion of the intake surface of the pump intake adapter that in operation does not contact the surface to be drained, and creates an open conduit between the pump intake adapter and the surface to be drained through which fluid may flow, the open conduit being in fluid communication with the connection on the pump intake adapter. Other systems and methods are provided.

A boat including a hull, a drain formed in the hull, and a plug engageable with the drain. The drain fluidly connecting a cavity formed in the hull to an exterior of the hull. The plug including threads engageable with threads of the drain. The plug is (i) moveable in a tightening direction to engage the threads of the plug with the threads of the drain and close the drain and (ii) moveable in a loosening direction to disengage the threads of the plug from the threads of the drain and open the drain. The plug also includes a handle having a receiver. The receiver having at least one disengaging surface configured to disengage a tool when the tool turns in the tightening direction and at least one engaging surface configured to allow the tool to loosen the plug when the tool turns in the loosening direction.
