Wake shaper: The invention of PerfectPass was a big step forward. Now so is the new Smart Plate. Supra's engineers invested three years in getting their hydraulic wake plate, Perfect Pass, Medallion gauges and Indmar engine to work together for this. The driver simply inputs a rider's name and touches the throttle. Smart Plate takes it from there, minding the acceleration, the plate deployment and the cruising. So easy.
