What do I need to smooth out my ride?

[Brendann99]

On glass like water if I do over 40-45mph my 96 starts hopping. From my searching I guess it's called porpoising? Repositioning my weight helps a little, If I steer slightly left or right it smooths out.

Is it possible for one of these skis to run WOT and have a smooth ride?

If so what would I need? Extended ride plate? sponsons? trim tabs? Which of these do I need or what combo? Or is there something else I can try?

96 XP???

It has a trim system. Trim out the bounce.

1. It is no longer functional. Stuck in the middle position. (I guess I should investigate a fix on it, but i never really used it before)

2. When it was functional it did little or nothing to stop the bounce.

So I guess my question is: What do sponsons do? what will an extended ride plate do? and what will trim tabs do for me?
