    Sounds like you now your stuff on real boats,
    And nice job on the prop you did.
    You can do some of mine next.

    Yes you can if you want to bend it and raise it,
    But why ?
    These cat hulls like to be run level.
    And just work the CG for ride attitude,
    I am not sure why there CG is so off and why there putting there pack so far forward.
    This is mine it is a modded Mystic and I was taking it easy with it.
    I did not have it taped up or any retrieval stuff with me,
    It ran pretty good with the setup.
    But I will be doing a few more mods to the boat.

    Raise your strut up 3/16. Most guys move their packs forward cause their struts are too low and it causes the bow to lift. Adding weight in the front is just a band aid. Simple strut raise is a much better solution

    So, if I understand correctly, you're saying that the COG setting should be used to keep the bow up a tiny bit to reduce wetted hull area, while keeping less prop in the water, to minimize prop-induced bow lift while maximizing prop-induced stern lift. Sounds like a plan.

    I raised the strut. There's about 3/16" of clearance still remaining between the prop and the strut frame, so it could still go higher if I wanted to.

    Hey,
    What boat do you have, BJ29, Mystic29, Geico29 ?
    And do you have any pictures of your setup or any video's of your boat running ?

    Yup that's what I'm sayin. You actually grasp this concept I see...
    You could Probly go higher, but just go in 1/8 increments at a time. You will notice a large improvement in handling raising it
