    Default Rideplate channel...

    My rideplate is just a flat plate that came with my setup from MPD. I've seen alot of guys add angle to the plate to strengthen it, it was also recommended to me to do the same. I'm curious, you guys who have done this, did you notice any difference in the boat and the way it handled?

    No handling differences, you will hear guys tell you it blocks water from dragging on the cradle and slows you down. We tested this at Ming on the clocks and with data and that is NOT true!

    Its there to keep the plate alive they get tweaked after only a few runs on a fast jetboat.

    i though i remember hearing that the plate can end up having a hook in it with all this force.. this what your talking about on "fast boats"?

    Deflection is what your trying to prevent, the entire boat is riding on the plate. You can imagine the forces in play.....

    is your plate bent?

    one more thing: all the stiffeners in the world wont keep the plate from bending if the cradle isn't machined at the right angle.

    my plate has some bow in it, i pretty much have to sit on the floor, and use my knee's to force the plate up to the cradle. Then stab the bolts and nut them. Once i do that i can tighten them down which brings the plate all the way up to the cradle. It seams like alot of force on that plate and on the shoe...

    why are you doing that? "start" the plate/shoe screws so the plate is kind of up in the notch, then tighten the cradle screws/nuts, then tighten the plate/shoe screws.
    there's no reason to use that much force get the plate attached to the cradle...

    if you want the plate to remain flat for awhile, add stiffeners. otherwise, it's gonna bow...

    I dont have a choice.. If i stab the shoe end and leave them loose it wont reach the cradel and vis verse. I have to stab the shoe side, leave them loose, then force the plate up so the cradel. Even with every shim MPD gave me with my kit installed it wont reach with out me putting some pressure on it.

    With the back cut it wasnt as bad, the tappered shoe made it worse.. Either way though both of shoes required some force to get the plate up high enough to even stab a bolt.

    I had that issue the first mock up day and i ended up taking more away from the hull where the plate comes out. Good thing we added glass on the inside. Maybe look there

    Anyone see the one piece channel rideplate in spam? Any one try it? Seems like a good idea.
