Making the paddlewheel efficent I can understand, as I've seen one in action. The propeller I can't. I can know that it is because people who know said so, but I don't understand it, something hasn't clicked in my head yet.
How can a prop reach that efficancy while it has to travel so far through the water? Since the tips of the blades have to move several feet through the water (and displace that water) for every inch forward the boat moves, how can they be efficent? I don't dispute it, I just don't understand it yet.
