Abstract: A wakeboat creates a wake, the performance level of the wake varying depending upon the mass of the wakeboat, the wakeboat including a hull; an engine supported by the hull; a controller supported by the hull; a processor coupled to the controller; a memory coupled to the processor; a sensor configured to measure at least one parameter of the wakeboat, the controller being coupled to the sensor and being configured to receive data from the sensor, the controller being configured to derive the present mass of the wakeboat from said sensor data, the controller being configured to determine the present wake performance level of the wakeboat based on the present mass of the wakeboat; and a tablet computer coupled to the controller, the controller being configured to use the tablet computer to indicate the present wake performance level of the wakeboat.

Abstract: 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.

Abstract: A wakeboat has a hull, the hull forming a wake when moving forward in the water, with a left quiet region and a right quiet region in the wake. The hull may exhibit rotation around one or more of its roll, pitch, and yaw axes which affects the quiet regions in the wake. A gyroscope supported in the hull may be used to rotate the hull around one or more axes. Such rotation may be used to create a surf left and/or surf right configuration, and measured via one or more sensors. Other systems and methods are also provided.

Abstract: A wakeboat includes a hull; a thruster associated with the hull of the wakeboat, the thruster configured to selectively impart lateral force to the hull; an operator control in the wakeboat configured to control a parameter of the wakeboat other than the thruster; a thruster control associated with the operator control, the thruster control selectively receiving input from the operator to control the thruster, the thruster control positioned to be operable with at least the same hand and/or fingers already operating the operator control. Other systems and methods for controlling a wakeboat are also provided.

Abstract: A wakeboat has a hull, the hull forming a wake when moving forward in the water, with a left quiet region and a right quiet region in the wake. The hull may exhibit rotation around its yaw axis which affects the quiet regions in the wake. Yaw rotation may be measured via one or more sensors. Yaw measurement may be used to control the hull and quiet regions. 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 to create a surf left and/or surf right configuration. Other systems and methods are also provided.

Abstract: 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. Left (port) and right (starboard) trim tabs are installed at the stern of the hull. Each trim tab comprises a primary subtab and a secondary subtab. Actuators may be optionally included to reposition the trim tabs more into, or more out of, the water. Such repositioning causes the disturbance on one side of the wake to be selectively repositioned to the other side of the wake, enlarging a quiet region on the side of the wake on which the repositioned disturbance was originally positioned. Other systems and methods are also provided.
