The stepped hydroplane concept, normally used on motor boats introduces air below a boat's hull so that less of the hull is in contact with the water and more area is planing
Spotted this on a trailer in a local marina recently with what at first sight looks to be some kind of new fangled jet drive, but in fact on closer inspection was revealed to be based on the same principle as the stepped hydroplane, namely to introduce air onto the trailing edge to reduce friction and increase speed.
Clearly this latest design is a much more sophisticated method for controlling and intoroducing differentiated air pressures into the water flow.
At the bow the retractable bowsprit combines what look like water pressure sensors as part of the system.
Can't wait to see it in action.
