I had an Idea the other day, this is just a theory, it is not tested, I thought it might be neat to try though. Here goes: If dimpling a golf ball makes the air stick to it longer, wouldn't dimpling the backside of a prop help suck more water over the next blade? it might even give enough suction to pull the boat forward more. Any thoughts? I know some racers leave the backs of the props rough, is that generally the same idea?
