Well, the shredmaster rideplate was designed by Bob Morgan for the Ultra 150 for racing when the racers basically complained about the handling of the 150/130 hull in rough waters. Long story short, here you go. I have tested it on 2 PWC's and it does what it says it does also:

they are a bit pricey I will admit bit I promise you, you won't regret it at all if you ride that 130 in any kind of chop!
