    03 GPR handling question

    Why would this hull bounce if water is flat? It only does it when at mid range speed, not over 55-60mph. Have played with trim, riding position, two riders, etc, what am I missing here? Mods in my signature.

    Try a search on "GPR Happy Dance". Might find some info there specific to your concerns.

    yup ^^^

    its called a chine walk... happens when the hull is coming up on plane.

    stepping the sponsons helps a little, but they all do it
