Here, they will incorporate cupping at the trailing edge of the prop, Power Boaters' found after cupping that the RPM reduces and Speed increases. It is like swimming with your hand cupped you will realise that you can pull better.The pitch of the prop had increased after cupping, but more importantly upon analysing with normal prop design the lift is concentrated at the front 30% of the blade whereas a cupped prop the lift is spread throughout the length of the blade. So it is not just going for higher pitch to get the speed but a more efficient and effective prop design.
