Oars and paddles operate by creating a pressure difference between the front and the back surfaces of the blade and so generate thrust. However, high-pressure backflows from the front of the blade into the low-pressure area at the back of the blade reduces this pressure difference and so limits the thrust of the blade and ultimately the velocity of the boat.
Mimicking how elite swimmers now swim with their fingers spaced apart, the Oscar BladesTM consist of multiple PowerSlitsTM which generate focussed water jets to counter the backflows and so increase thrust.
On-water tests carried out by independent rowers have shown winning time advantages over 500m of 1 to 2 seconds at full pressure. Trials were carried out according to the Concept2 protocol of 6 x 500m pieces rowed at full pressure, supervised by an independent coach.
