    I think a ride plate would help.

    sounds as if you are fixing to get pitched out of the boat if it ever hooks.
    what speeds are you talking about when it does this?

    the fin seemed to help a little, dont know a whole lot about this type of hull but seems to be solid there is not to many of these boats out there that i have seen

    I second getting rid of the rudder. Pain in the ass will get broke off eventually anyway. They don't really help much either. Take a look at some of the photos here and you'll hardly ever see one. Literally hundreds of boats and very few with rudders.

    Check your grate/loader too. Make sure it's not broken or cracked at the welds. This will definitely cause you problems.

    The rudder depends on the boat. I had a CP that when they broke off you couldn't tell (used 2). My Carrera bow rider on the other hand with out it gets squirelly. I have a ride plate, Droop, and diverter on the Carrera.
    With out the rudder it acts almost the same as to much diverter, without the porposing.
    I am not sure if what you are describing is chine walking, but you might be able to improve it if you can get the bow down.

    Does the intake still have the side dorsel fins?, Is what you are referring to maybe bowsteer? how much play do you have in your steering system?

    Unfortunately, I guess I have more questions than answers

    We had a Spectra 20 that liked to "Walk the walk" at close to 60MPH and a rudder and tighter steering system solved all issues..

    Good luck.
