    Two types of steps:

    The first (older) type of step simply aerates the hull.

    The second type of step that is becoming more and more common now is the Harry Schoell Duo-Delta Conic hull which has one large pronunced "step" forward.

    Thanks for the info!. That's how I had thought it had worked. Another question if I may on the same subject.

    I used to be a neighber to a small hydroplane racer. On his boats there was a small strip fore of the prop that I was told caused the water to be "denser" just before the prop allowing it to bite better. I don't know how true this is, but he was a world record holder in the 500cc class with this boat.

    If this is true the it seems the stepped design would negate some of the prop effeciency by airating (spelling?) or disturbing the water before it got to the props. Am I way off here?

    Thanks
    Jesse
