Moomba has the Flow surf (2.0 or 3.0)system where-as Supra has the Swell system. In principle they do the same thing through right/center/left plates. They both create yaw in the boat to improve wave dynamics and tuning of the wave through the Autowake system. The Autowake system incorporates sensors and controls to consistently produce your wave based on preset parameters or user selectable parameters. Autowake triggers to side and center plates to preset positions and uses the pump and ballast system to obtain pitch, roll, and displacement for the preset, or user selected options.
Supra has more displacement due to hull shape and ballast, but both require additional ballast to optimize wave.
An upgrade for the Moomba is the G6 pump system, which is standard for Supra.
Supra has the Vision control system, which offers on screen control, and some manual control on the steering wheel. Moomba has two screen options, and toggle controls for ballast, plate controls, and speed controls.
Supra offers more automation and some additional adjustment. You have to compare both to understand.
The following links can help you understand some of the differences between the two different boats.
